BOINC: compute for science

BOINC: compute for science
BOINC is a program that lets you donate your idle computer time to science projects like SETI@home, Climateprediction.net, Rosetta@home, World Community Grid, and many others. After installing BOINC on your computer, you can connect it to as many of these projects as you like. You may run this software on a computer only if you own the computer or have the permission of its owner. Tested on the current Ubuntu distribution; may work on others. If available, we recommend that you install a distribution-specific package instead. After downloading BOINC you must install it: typically this means double-clicking on the file icon when the download is finished.

GPU computing - BOINC Most computers are equipped with a Graphics Processing Unit (GPU) that handles their graphical output, including the 3-D animated graphics used in computer games. The computing power of GPUs has increased rapidly, and they are now often much faster than the computer's main processor, or CPU. Some BOINC-based projects have applications that run on GPUs. Check whether your computer has a capable GPU Note: Some projects may have additional requirements. Get the latest BOINC software Download and install the latest version of the BOINC software. Warning: On Windows do not install BOINC in Protected Access Execution (PAE) mode aka service mode (6.4.5 - 7.0.28) or Service Install mode (7.0.64 and above). Get the latest driver Run BOINC; In BOINC up till 6.10, look at the Messages. You can get the latest video drivers from: Get latest NVIDIA driver (Mac users: you need a special CUDA Driver; Fedora users: refer to this page). Attach to projects with GPU applications You're done!

Twilight of the GPU? If a new offering really works, it may substantially shrink the market for gaming consoles and high-end gamer PCs. Their demo runs Crysis – a game known to melt down extreme PCs – on a Dell Studio 15 with Intel's minimalist integrated graphics. Or on a Mac. Or a TV, with their little box for the controls. This game-changer – pun absolutely intended – is Onlive. What Onlive does seems kind of obvious: Run the game on a farm/cloud that hosts all the hairy graphics hardware, and stream compressed images back to the players' systems. Now, I'm sure some of you are saying "Been there, done that, doesn't work" because I left out something crucial: The client also must send user inputs back to the server, and the server must respond. That's where a huge potential hitch lies: Lag. Of course Onlive claims to have solved that problem. Lag The golden number is 150 msec. There is robust skepticism that this is possible. They also said their servers were "like nothing else." Angry ISPs

ATI Stream Computing: второе пришествие В результате стремительного развития компьютерной отрасли графические процессоры (GPU) последних поколений превратились в мощнейшие вычислительные устройства. Производители игровых ускорителей настойчиво убеждают нас в том, что их современные разработки успешно справляются не только с обработкой графических данных, но и с любыми другими ресурсоёмкими задачами, которые хорошо поддаются распараллеливанию. Утверждается, что по сравнению с центральными процессорами (CPU) графические чипы в некоторых случаях могут демонстрировать в десятки раз большую производительность. К счастью, идея приспособить видеокарты к нестандартным вычислениям существует не только на словах. Около двух лет назад компании NVIDIA и AMD анонсировали технологии CUDA и ATI Stream Computing. Один из первых суперкомпьютеров Cray-1, построенный в 1975 году, позволял добиться суммарной вычислительной мощности около 0,0008 терафлопс. Перейдём к самому интересному.

Cosmology@Home BOINC CUDA Zone— Подробнее о CUDA Что такое CUDA? CUDA – это архитектура параллельных вычислений от NVIDIA, позволяющая существенно увеличить вычислительную производительность благодаря использованию GPU (графических процессоров). На сегодняшний день продажи CUDA процессоров достигли миллионов, а разработчики программного обеспечения, ученые и исследователи широко используют CUDA в различных областях, включая обработку видео и изображений, вычислительную биологию и химию, моделирование динамики жидкостей, восстановление изображений, полученных путем компьютерной томографии, сейсмический анализ, трассировку лучей и многое другое. Параллельные вычисления с CUDA Направление вычислений эволюционирует от «централизованной обработки данных» на центральном процессоре до «совместной обработки» на CPU и GPU. Говоря о потребительском рынке, стоит отметить, что почти все основные приложения для работы с видео уже оборудованы, либо будут оснащены поддержкой CUDA-ускорения, включая продукты от Elemental Technologies, MotionDSP и LoiLo.

Asteroids@home About Asteroids@home Asteroids@home is a research project that uses Internet-connected computers to do research in Asteroids@home. You can participate by downloading and running a free program on your computer. Asteroids are the most numerous objects in the solar system. So far, hundreds of thousands of asteroids are known, with hundres of new discoveries every day. Because asteroids have in general irregular shapes and they rotate, the amount of sunlight they scatter towards the observer varies with time. The project Asteroids@home was started with the aim to significanly enlarge our knowledge of physical properties of asteroids. Because the photometric data from all-sky surveys are typically sparse in time, the rotation period is not directly 'visible' in the data and the huge parameter space has to be scanned to find the best solution.
