  2. Does your smartphone’s battery drains faster? Or you want your phone’s power to last longer? Well, I think it’s every person’s wish that their phone’s battery lasts longer so that they don’t need to charge it frequently and they can play games, watch movies, surf internet etc. without any trouble. But what is the main reason behind this quick drainage of battery? If your battery power is good but still it doesn’t last longer then the problem might not be with the battery but with your phone and the apps installed in it. Sometimes a lot of processes keep running in the background which consume a lot of battery. And some of the apps also tend to consume more battery power. Due to this, the phone’s battery drains faster. So, for resolving this problem you need to have an application which can improve the level of your phone’s battery life. There are many such applications and today I’m going to review one of the best such applications which can help you to extend the battery life of your smartphone and that application if Power battery – battery saver. Power Battery – Battery Saver app In-depth Review Power Battery- Battery saver application is an Android app developed by LionMobi. The app is designed such that it helps to prevent quick drainage of the phone’s battery. It lets you know that which apps are consuming excessive power so that you can stop them. The app also provides an estimate of how long your smartphone battery will last. It keeps checking your phone for the points of battery leak and tries to repair them. There are many other features of this app which are explained below. Interface Starting with the interface of Power battery- battery saver application, the app provides you a clean and systematic interface. All the main features are displayed in a perfect manner so that it doesn’t make it difficult to find any button or feature. When you first launch the app, you will see many panels with different information and functions. The color combination is also attractive and due to which its easily highlights all its control button and links. You need to scroll downwards for accessing all its functions. Also, there are controls such as WiFi, brightness, ringtone, data, etc. available in the app itself, so that you can quickly access these whenever required to enable or disable a particular function just to save more battery. Battery life estimation Now you can easily know how long will your battery will last in different scenarios. Power battery- battery saver app provides you a nearly accurate battery life estimation using special statistics algorithm for different situations. It tells you the hours, the battery will last if you use WiFi, Bluetooth, play games, etc. In our test, the app did a great job. The battery estimation was almost accurate. We tested the app in different mobiles and the results were quite good, the battery lasted for the hours which power battery application estimated. Power saving and protection The main cause of excessive battery draining is power-draining apps which cause your phone to use more and more power resulting in high battery drainage. But now, as power battery-battery saver app is all you need to have to stop all those power-draining applications which run in the background continuously. The power protection is one of the best features provided by this application. All you need to do for activating this tool is just tapping the Power protection option available at the home screen and rest of the work will be done by the app automatically, the app will show you a detailed list of the apps which are consuming more battery and then you can disable those apps from the background. This will eventually increase the battery life. Don’t worry the app will not close important apps that you are using. It will give you all the sources of battery drain and you can keep or close the app yourself. Memory management To speed up your phone for a better performance, it is quite necessary to clean the memory of your phone. Well, you don ‘t need any other app for the same as Power battery – battery saver app offers you the same. You can optimize the speed of your device just by tapping the optimize button given at the top os the screen of the app. Custom power safe The app provides a power save mode that you can activate according to your need. Besides you can even customize your own mode for the custom setting. The app offers you 4 modes of power saver viz. prolong, general, sleep and default. Each mode has its own setting such as if you activate prolong mode, the brightness will become 10%, screen timeout 15s, Wifi will be off, auto sync will be off and so on. And whenever you activate any of the modes all the settings for that mode will be applied immediately. Displays battery information Now you don’t have to search over the internet to get the information of your battery or peeling off the back cover to do the same. Power battery- battery saver application displays every detail of your battery such as health status, temperature, current power, full power voltage etc. You can even get the information about current day’s battery usage along with app name and the amount of power used by that app as you can see the below image. Some other features Charge This feature makes the charging process quicker. While charging your phone, the app blocks all the excessive power consumption apps which obviously boosts the charging and makes your phone get fully charged quickly. Also, the app shows you the charging record of 30-days. Battery skin This feature is just for changing the graphics. You can change the battery icon using battery skin option. Just tap on the app icon present at the top left corner of the main screen, it will show up the menu items from where you need to select battery skin. Now you can choose any of the icons of your choice.

    Privacy is Power

    The desk I’m typing this on is a little wobbly. I adjusted the legs yesterday to be a little shorter after noticing the reason my wrists were hurting was because they were bent upward at an uncomfortable angle. My office at home is now clean and empty, after spending several hours the day before throwing away empty boxes of electronics that I for some reason found value in keeping. I also finally fixed our “broken” bathroom door, which for the last three months wouldn’t shut all the way for some complex reason that I never took the time to investigate. Turns out it was a loose screw. Righty tighty. Being in an existential crisis is surprisingly good for doing things around the house. My latest bout with my brain’s reality was about the project I’m working on: a notes app that focuses on privacy. It encrypts your notes on your device before it sends it to the server. Why? For your privacy. Why? I don’t know. And so it begins. What’s the point?, I cry. What if this whole privacy wave we’re all swimming in ends up being shallow? What if this war we’re waging ends up being a cold war between ourselves and those we aim to hide information from, and it one day ceases to be the looming threat it is today? What if this monster we claim is out to eat our information turns out to be just a shadow? The whispers begin pointing at me. What if I’m putting all this time into this for nothing? I mean, do you even care about privacy? Ouch. But here, after being pushed to the bottom, I found a small strand of reason, and it reasoned with me: Privacy isn’t about you. It’s about all of us. To worry about privacy today, even though you may have no compelling reason to, is one of the largest contributions you can make to the future of humankind and the nature of governance. Privacy is about power. Many of us have taken a middle school course on civics, and the functioning of the U.S government. You know, three branches of government and checks and balances, or you may remember it as, like that’s ever going to come up. Enter February 2017. Oh. We owe this balanced functioning of a government to the strong paranoia of several individuals 240 years ago, enacting what can be described as even ridiculous measures to ensure some abstract functioning of a government that hadn’t even begun yet. None of these individuals reaped any tangible benefits from their actions and contributions in their lifetime. But without them, our lives and reality today would be very different. Many of us are today exhausted worrying after our privacy, not knowing how to keep up with the newest trends in encrypted messaging apps or which new wire-tapping programs can monitor which type of software on what port over what technology. And after the initial burst of adrenaline rush from hide-and-seek wears off, it’s easy to feel worn out, especially because we aren’t seeing any tangible benefits to our efforts. But privacy isn’t just about you or me, and what immediate returns we may see on our investment. It’s about the future of power. Of ensuring a system of checks and balances between ourselves and our governments and other large entities. There is a reason the information we produce is so cherished by these entities, and they will fight till the end to make sure our information is in their control. And because these entities are already so much more powerful than the collective privacy conscious, self-doubt and defeat is a reoccurring event. Battles may be lost, but never doubt the significance of this cause. A paranoia is in the air, like the paranoia of 1776. Don’t ignore it. Don’t believe it isn’t real. Don’t believe it’s not important. You are creating a better future for the people of 2217. And as humans who live comfortably today on the contributions and sacrifices of those before us, we owe it to contribute just as much to ensure a better life for our descendants. The fight for privacy will wage on for the next hundred years, and it starts with the actions, sacrifices, and decisions we make today. As humans in this century, some of the most important byproducts of our existence is the information produced and stored in our emails, notes, and messages. And make no mistake about it: this information belongs to you, and to no one else. You can join the fight for a balanced control of power by using and supporting applications that strive for privacy first and foremost.

  4. The material known as magnetoelectric multiferroic is developed by researchers at the University of Michigan. A false-colored electron microscopy image shows alternating lutetium (yellow) and iron (blue) atomic planes Researchers at the University of Michigan have engineered a new material – magnetoelectric multiferroic – which could boost the computing power of the next-gen electronic devices, while consuming less energy. The material wraps electrical and magnetic properties at room temperature and relies on a process called planar rumpling. By combining individual layers of atom the material produces a thin film having magnetic polarity which can be flipped from positive to negative or the other way around with small electricity pulses. Researchers claim that device-makers could use this property in the coming days to store digital 0's and 1's. The demand for the room-temperature multiferroic is huge in the electronics filed as they require a less amount of power to read and write data than what the current semiconductor-based computers need. Besides, when power is shut, the data remains intact. And, because of these properties multiferroic devices require only brief pulses of electricity as against the constant stream that's needed for today's electronics. The new devices would use an estimated 100 times less energy. Ramamoorthy Ramesh, associate laboratory director for energy technologies at Lawrence Berkeley National Laboratory said: "Today, about 5 percent of our total global energy consumption is spent on electronics, and that's projected to grow to 40-50 percent by 2030 if we continue at the current pace and if there are no major advances in the field that lead to lower energy consumption." To create the new material, researchers used thin and film of hexagonal lutetium iron oxide (LuFeO3). "We were essentially spray painting individual atoms of iron, lutetium and oxygen to achieve a new atomic structure that exhibits stronger magnetic properties," said Darrell Schlom, a materials science and engineering professor at Cornell. John Heron, assistant professor in the Department of Materials Science and Engineering at the University of Michigan, said a viable multiferroic device is not likely soon, although the initiative taken in the field puts it closer to its goal of making computer with improved speed.

    Opera Power Saver launches

    Opera Power Saver is a new feature implemented in Opera 39 designed to improve battery life of mobile device when Opera is used as a web browser. A new Power Saver icon appears in Opera's main toolbar when the power cable of the laptop is unplugged from the device, This indicates that power saver mode is ready for use. A click on the icon reveals whether the feature is enabled or not, and a toggle lets you switch its state easily. The browser will suggest to enable the power saver mode automatically when battery of the device is running low so that you can squeeze additional minutes of screen time out of the device before it runs out. Opera Power Saver Mode You find an option in the settings under browser to always show the power icon, but there does not seem to be a preference right now to always enable power saver mode when the device is unplugged. The power savings come from optimizations such as reduced background tab activity, video playback parameter tuning and an adaptive page-redrawing frequency according to Opera. How good is Opera Power Saver? Opera ran tests to compare the power saver mode of the Opera browser to other browsers, and in particular Google Chrome and Opera without power saving mode. According to the company's test, Opera 39 Developer Edition was able to run 3 hours longer than "browsers like Google Chrome" on a laptop running a 64-bit version of Windows 10. While this has to be confirmed by independent tests and especially on more devices, it is quite an impressive feat. Still, mileage may vary depending on the laptop in question, the web activity and other activity on the device. The new feature does not keep track of statistics currently which makes it difficult to judge its effectiveness when it comes to the power saving functionality on individual devices. It would be great if the browser would make some calculations in the background to provide information about the average power consumption when power saver is enabled and when it is not. All in all, it is an interesting new feature that sets Opera apart from competing browsers. I wish it would offer more options and statistics though. The new power saving mode is just one of the new features that Opera Software added to the web browser this year. The company launched a native ad blocker in Opera Stable this month for instance, making it the first major web browser (from a market share point of view) to do so. Another first was the integration of a browser proxy in Opera which improves privacy while Opera is being used. Opera Developer can be downloaded from the official Opera website, and it can be installed alongside the stable version of the web browser. Article source
  6. Incredible lightning storm breaks out while lava shoots into the sky as Japanese volcano erupts thirty miles from nuclear power plant A volcano in southern Japan dramatically erupted near a nuclear station Sakurajima is one of the most famous of Japan's volcanoes on Kyushu The volcano's lava and rocks have already began to cause havoc A volcano in southern Japan dramatically erupted today just 50km from the Sendai nuclear station, sparking fears of a potential disaster A volcano in southern Japan has dramatically erupted today just 30 miles (50km) from the Sendai nuclear station, sparking fears of a potential disaster. Sakurajima is one of the most famous of Japan's volcanoes, standing at 1,117-metre (3,665-foot) high and located in a scenic bay on the southern island of Kyushu. Although there have been no reports of any fatalities, fiery hot lava has been flowing down the volcano's slopes and smoke rising skyward. The Japan Meteorological Agency said on its website that Sakurajima in southern Kagoshima prefecture erupted at 6:56 pm (0956 GMT). The closest nuclear reactors, sitting some 50 kilometres from the mountain, remains in operation but concerns remain activists that the volcano could pose a serious safety risk. The weather agency raised the volcano's alert status to Level 3, which bans entry onto the mountain, from Level 2, which limited people from going near the vents. The elevated level, however, stopped short of urging local residents to prepare for possible evacuation, according to the agency. Local police have received no immediate report of damage on the peninsula of Sakurajima, where the volcano is located, which has a population of about 4,000 people. The volcano sits about 12 kilometres across a bay from the main part of the city of Kagoshima, with a population of more than 600,000 people, on the southern main island of Kyushu. The volcano frequently spits out smoke and ash and is a major tourist attraction and one of Japan's most famous sites. Sakurajima last went through a major eruption in 2013, spewing an ash plume up to 5,000 metres into the air, causing damage but no major injuries. There are scores of active volcanoes in Japan, which sits on the so-called 'Ring of Fire', where a large proportion of the world's quakes and eruptions are recorded. In September 2014, Mount Ontake in central Nagano prefecture violently erupted, leaving 58 people dead and five others missing in the nation's deadliest eruption for almost 90 years. Article source
  7. Power consumption has risen to importance in the browser world ever since mobile became the new battle ground. While it is not the only metric that matters and probably not something that most users pick a mobile browser by, it seems to gain some prominence lately due to mobile device power requirements and a lack of breakthroughs in battery technology. A study from 2014 by Anandtech compared the battery life of a Dell XPS 15 laptop when running popular browsers and Firefox did not perform overly well in the test when compared to Internet Explorer specifically. Firefox is not the only browser that could do better though. A recent test by the Verge showed that Chrome tapped out after less than 10 hours on a new MacBook Pro with Retina display while Safari did not until 13 hours had passed. Another recent test concluded that Chrome is doing worst when it comes to battery usage followed by Firefox and then Internet Explorer. There is also the Energia Dashboard highlighting cpu and power consumption of Firefox, Chrome and Internet Explorer on popular websites. Mozilla's Project Candle aims to improve the power consumption of Firefox on all platforms it is offered on (meaning desktop, mobile and Firefox OS). This is done mostly by evaluating power bugs that exist on Bugzilla but also by adding new bugs that introduce power-related improvements to Firefox to Bugzilla. The team is working its way through all power-related bugs currently to sort them by priority. It plans to address high priority bugs first, for instance those that affect many users of the browser or will result in power improvements that are not site-specific. The main list of power related bugs is available on this Bugzilla page. Please note that it mixes desktop, mobile and Firefox OS bugs. Mozilla hopes to reduce power usage in all versions of Firefox by addressing these bugs and implementing new power saving methods in the browser. The organization notes that doing so may also have an effect on performance as fixes may result in lower cpu usage among other things. Developers and Firefox users who are interested in this new project can check out the official discussion mailing list (archive) over on Google Groups. Closing Words All recent benchmarks show that Firefox could do better when it comes to power consumption, and that's exactly what Mozilla aims for in Project Candle. Source
  8. It's no secret that Chrome for Mac (OS X) is a mess. It eats a ridiculously high amount of memory, energy and shortens the battery life. Google announced earlier this year that it was working on a fix. And now it is delivering on that promise. The latest Chrome build -- available via Canary channel -- is significantly less resource hogging, and surprisingly faster at the same time. The company has been hard at work improving the memory consumption in its Web browser while also making the tabs snappier. You can read about the development process and feedback at Chromium's developer website. The build dubbed 45.0.2454.46 is also significantly lighter on the battery and is no longer making the laptop crazy hot. In a recent build, the company was testing interesting internal processes like tab discarding in the background. The idea behind it is simple: make the tabs you haven't used in awhile idle automatically. This would, under the typical condition, free up a significant amount of memory. The company also made some changes in the stable version of Chrome earlier this month to increase the responsiveness of Web applications. “Starting in Chrome 41, V8 takes advantage of a new technique to increase the responsiveness of web applications by hiding expensive memory management operations inside of small, otherwise unused chunks of idle time. As a result, web developers should expect smoother scrolling and buttery animations with much reduced jank due to garbage collection”, it noted in a blog post. The stable version of Chrome, however, doesn't offer these features just yet. But since it is already on version 44, we expect the version 45 to release on Windows and Mac soon. Till then, you can try out the beta build, though do note that due to its nature, it might have many rough edges, and could crash and trigger unanticipated actions. Source

  11. By Rahul Bali February 13, 2014 Supercomputers were introduced in the 1960s, made initially and, for decades, primarily by Seymour Cray at Control Data Corporation. While the supercomputers of the 1970s used only a few processors, in the 1990s machines with thousands of processors began to appear and, by the end of the 20th century, massively parallel supercomputers with tens of thousands of “off-the-shelf” processors were the norm. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling like computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals, physical simulations such as simulations of the early moments of the universe, airplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion. Throughout their history, they have been essential in the field of cryptanalysis. Supercomputer operating systems have undergone major transformations, as sea changes have taken place in supercomputer architecture. While early operating systems were custom tailored to each supercomputer to gain speed, the trend has been to move away from in-house operating systems to the adaptation of generic software such as Linux. 476 of the top 500 fastest supercomputers, 95.2 percent, in the world run Linux. Linux has ruled supercomputing for years. But, it wasn’t always that way. In 1993, the first successful Linux distributions, Slackware and Debian were only just getting off the ground. Before Linux made its move, Unix was supercomputing’s dominant operating system. Since 2003, the top operating system by performance share on the Supercomputer List underwent a complete flip from 96 percent Unix to 96 percent Linux. By 2004, Linux had taken over the lead for good. According to The Linux Foundation, “Linux [became] the driving force behind the breakthroughs in computing power that have fueled research and technological innovation. In other words, Linux is dominant in supercomputing, at least in part, because it is what is helping researchers push the limits on computing power.” 10. SuperMUC (IBM) SuperMUC, the successor of the Höchstleistungsrechner Bayern II, is a new supercomputer of the Leibniz Supercomputing Centre in Garching near Munich, available for European researchers to use to probe the frontiers of medicine, astrophysics and quantum chromodynamics and other scientific disciplines such as computational fluid dynamics, computational chemistry, life sciences, genome analysis and earth quake simulations. SuperMUC was named the second fastest supercomputer in Europe in November 12, 2012 at International Supercomputing Conferencein Hamburg, Germany. It is also the fastest Intel-compatible system in the world. The SuperMUC will have 18,432 Intel Xeon Sandy Bridge-EP processors running in IBM System x iDataPlex servers with a total of 147,456 cores and a peak performance of about 3 petaFLOPS. The main memory will be 288 terabytes together with 12 petabytes of hard disk space based on the IBM General Parallel File System. It will also use a new form of cooling that IBM developed, called Aquasar, that uses hot water to cool the processors, a design that should cut cooling electricity usage by 40 percent, IBM claims. SuperMUC runs SUSE Linux Enterprise Server. 9.Vulcan (IBM) Located at the Lawrence Livermore National Laboratory in California, the Vulcan supercomputer is devoted to both government use and collaborative endeavours of industry and research universities. Its 393,216 cores run at 4.3 petaflops, which are based on IBM’s Blue Gene/Q supercomputing technology. It also consists of 24 racks and 24,576 compute nodes, placing it within LLNL’s high performance facility, together with the Sequoia. Vulcan runs Red Hat Enterprise Linux. 8. JUQUEEN (IBM) JUQUEEN at the Forschungzentrum Jülich is a 28-rack Blue Gene/Q system, and per June 2013 the highest ranked machine in Europe. The JUQUEEN will be rocking 458,752 cores with a peak performance of about 5,872 Tflops. JUQUEEN runs Red Hat Enterprise Linux. 7.Stampede (DELL) On January 7, 2013, TACC’s new cluster, “Stampede”, went into production. Stampede comprised 6400 nodes, 102400 cpu cores, 205 TB total memory, 14 PB total and 1.6 PB local storage. The bulk of the cluster consisted of 160 racks of primary compute nodes, each with dual Xeon E5-2680 8-core processors, Xeon Phi coprocessor, and 32 GB ram.The cluster also contained 16 nodes with 32 cores and 1 TB ram each, 128 “standard” compute nodes with Nvidia Kepler K20 GPUs, and other nodes for I/O (to a Lustre filesystem), login, and cluster management. A pre-production configuration of Stampede was listed as the 7th fastest supercomputer in November 2012 with a delivered performance of 2660 TFlops. Because the system was still being assembled, the submitted benchmark was run using 1875 nodes with Xeon Phi coprocessors and 3900 nodes without Xeon Phi coprocessors. In June 2013 , the benchmark was re-run using 6006 nodes (all with Xeon Phi coprocessors), delivering 5168 TFlops and moving the system up to 6th place. Stampede runs Cent OS Linux. 6. Piz Daint (Cray) The Piz Daint supercomputer is not only the sixth most powerful machine in the world but also the fourth most energy-efficient. It’s also one of only two supercomputers in the top 10 of the efficiency ranking that’s capable of maintaining petaflops performance. Located at the Swiss National Supercomputing Centre, in Lugano, Piz Daint is being used to parse huge data sets and simulate processes for projects in geophysics, materials science, chemistry, and other areas, but especially in climate modeling. To power that research, the computer uses a hybrid system that combines the advanced network architecture of the Cray XC30 with two cutting-edge processors, the Intel Xeon E5 CPU and the Nvidia Tesla K20X GPU. The computer’s 5272 compute nodes are bound together in a special low-latency network to form an unusually compact machine. Piz Daint, in operation at CSCS since April 2013, has gone through a major upgrade in October 2013. During this phase the supercomputer based on Intel® Xeon® E5 processors has more than doubled in size from 12 to 28 cabinets and has been upgraded to a hybrid architecture featuring NVIDIA® Tesla® K20X graphical processing units (GPUs). With a total of 5’272 hybrid compute nodes as well as a powerful high-bandwidth, low-latency network, it will now be possible for real simulations to with a peak performance of 7.787 petaflops. Piz Diant runs Cray Linux Environment. 5. Mira (IBM) Mira, a petascale Blue Gene/Q supercomputer, was constructed by IBM for Argonne National Laboratory’s Argonne Leadership Computing Facility with the support of the United States Department of Energy, and partially funded by the National Science Foundation.Mira will be used for scientific research, including studies in the fields of material science, climatology, seismology, and computational chemistry.The supercomputer is being utilized initially for sixteen projects, selected by the Department of Energy.

Sequoia (IBM) IBM Sequoia, a petascale Blue Gene/Q supercomputer, constructed by IBM for the National Nuclear Security Administration as part of the Advanced Simulation and Computing Program (ASC). Record-breaking science applications have been run on Sequoia, the first to cross 10 petaflops of sustained performance. The cosmology simulation framework HACC achieved almost 14 petaflops with a 3.6 trillion particle benchmark run,while the Cardioid code, which models the electrophysiology of the human heart, achieved nearly 12 petaflops with a near real-time simulation. Sequoia will be used primarily for nuclear weapons simulation, replacing the current Blue Gene/L and ASC Purple supercomputers at Lawrence Livermore National Laboratory. Sequoia will also be available for scientific purposes such as astronomy, energy, lattice QCD, study of the human genome, and climate change. Sequoia is a Blue Gene/Q design, building off previous Blue Gene designs. It consists of 96 racks containing 98,304 compute nodes. The compute nodes are 16-core PowerPC A2 processor chips with 16 GB of DDR3 memory each. Thus the system contains in total 1,572,864 processor cores with 1.5 PiB memory. It covers an area of about 3,000 square feet. The computer nodes are interconnected in a 5-dimensional torus topology. In January 2013, the Sequoia sets the record for the first supercomputer using more than one million computing cores at a time for a single application. The Stanford Engineering’s Center for Turbulence Research used it to solve a complex fluid dynamics problem — the prediction of noise generated by a supersonic jet engine. 2. Titan (Cray) Titan is a supercomputer built by Cray at Oak Ridge National Laboratory for use in a variety of science projects, dealt mostly with molecular scale physics or climate models. Titan is an upgrade of Jaguar, a previous supercomputer at Oak Ridge, that uses graphics processing units in addition to conventional central processing units. It is the first such hybrid to perform over 10 petaflops. The upgrade began in October 2011, commenced stability testing in October 2012 and it became available to researchers in early 2013. The initial cost of the upgrade was US$60 million, funded primarily by the United States Department of Energy. Titan will itself be replaced by an approximately 200 petaflops system in 2016 as part of ORNL’s plan to operate an exascale (1000 petaflopsto 1 exaflops) machine by 2020. Titan employs AMD Opteron CPUs in conjunction with Nvidia Tesla GPUs to improve energy efficiency while providing an order of magnitude increase in computational power over Jaguar. It uses 18,688 CPUs paired with an equal number of GPUs to perform at a theoretical peak of 27 petaflops. This was enough to take first place in the November 2012. Titan runs the Cray Linux Environment. 1. Tianhe-2 (NUDT) Tianhe-2 is a 33.86 petaflops supercomputer located in Sun Yat-sen University, Guangzhou, China. It was developed by a team of 1300 scientists and engineers. It is the world’s fastest supercomputer as of November 2013. According to NUDT, Tianhe-2 will be used for simulation, analysis, and government security applications.

  12. This is something most are familiar with.. But incase there are noobs on here, w/an older PC or laptop, looking to get the most out of their machines.. I disable all non-essential services, and create .CMD shortcuts to turn them on when i need them. this reduces CPU and Memory load.. thereby improving overall responsiveness.. Included are .CMD shortcuts for: Power Scheme: i set my laptop to Power Saver every night, and have it hooked up to my stereo while foobar plays the audio of documentaries i've downloaded & converted :)VMware: i have all VMware related services disabled. . and when i need it.. i simply enable the services.. takes a second.VPN: since i have ESET installed.. Windows Firewall can be disabled.. but VPNs require Firewall service among a few others.. so i've created .CMD shortcuts to enable/disable all related services. (if you need a free/reliable VPN service, i use VPN Gate.)Windows Backup: same thing.. it's only required to run right before backing up.Windows Update: same thing.. why waste badwidth when you only need to check once a week.File: CMD.zip CRC: 5AE965BC Size: 4.50 KB (4,613 bytes) How to use: Create a CMD folder under %USERPROFILE%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs.Copy content into created CMD folder.and it should show up on the Start Menu. UPDATE December 9, 2013Found an extremely useful script, which uses wevtutil, for clearing Windows 7 Event Logs for a more responsive OS Do this once a week.. (i do it once a day.. i have no need for the logs.. and disabling Event Log will cause problems.. so DON'T disable)Download: http://paste2.org/Nt00nMIJ Copy & save with Notepad as *Name*.cmdNOTE: noobs would like to argue, clearing the Event Log is dangerous or useless.. that's because they haven't tried or is confusing w/disabling the service. :)
