About CAS@home

CAS@home is hosted by the Computing Centre of the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences. CAS@home is a volunteer computing platform for Chinese scientists based on the BOINC volunteer computing software. CAS@home collects the volunteer contributions to computing resources for scientists at the Chinese Academy of Sciences and other Chinese research institutions, to provide massive free computing resources that help the scientists complete major scientific computing tasks. Therefore, CAS@home supports multiple applications. The first application to be launched on CAS@home was developed by scientists at the Institute of Computing Technology (ICT), Chinese Academy of Sciences. It focused on protein structure prediction application (software called SCThread). In addition, Tsinghua University's Centre for Micro and Nano Mechanics (CNMM) an interdisciplinary innovation research center, has prepared an application for simulating flow of fluids and motion of solids on the nanoscale. Beijing Institute of Genomics (BIG), Chinese Academy of Sciences, is preparing an application for gene sequencing for applications in cancer research. And physicists of the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, are preparing an application for simulating particle collisions at the Beijing Electron Positron Collider, based on software called BOSS.

About the CAS@home maintenance and development team

CAS@home was set up by the Computing Centre of the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences. The IHEP team is responsible for maintenance and development, key personnel, currently coordinated by Wu Wenjing, and including Wu Jie and Kan Wenxiao, under the leadership of Chen Gang, and with help from David Anderson (Space Science Laboratory, U.C. Berkeley), Francois Grey (Tsinghua University and Citizen Cyberscience Centre, CERN) and Lei Yang (Tsinghua University). The CAS@home team is committed to the deployment and maintenance of the BOINC software, the development and maintenance of the CAS@home platform for Chinese scientific applications, the operations management and data collection platform development. We wholeheartedly welcome volunteers to assist our maintenance and development team and help us build a better scientific volunteer computing platform. If you have any wishes, please contact us.

About the Institute for High Energy Physics (IHEP)

The Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, specializes in basic particle physics research. It is located in Yuquan Road, Shijingshan District, Beijing. IHEP's main tools are the Beijing Electron Positron Collider (BEPCII) and the Beijing Spectrometer (BES). Research at IHEP includes experimental physics, theoretical physics, astrophysics, synchrotron radiation accelerators, and advanced computing. The Beijing Electron Positron Collider at the IHEP is in an underground area that look like a huge badminton court. It involves a storage ring that is 240 m in circumference and a 202 m long traveling-wave linear accelerator. The Beijing Spectrometer is located on the accelerator track. It can intercept the particles produced by collisions between electrons and positrons in the storage ring, and provides a variety of information about new fundamental particles. Physicists extract this information using advanced computing, including physical reconstruction and physics analysis of the data, as well as simulations of the collisions. Physicists use the results to explore the basic units of composition of matter.

High Energy Physics research projects involvebroad international cooperation, so the Institute of High Energy Physics and the world's major countries have established deep relations of cooperation. The important cooperative research institutions include the European Organization for Nuclear Research (CERN), the Japan Institute of High Energy Physics (KEK), Fermilab near Chicago (the Fermi Lab), the Stanford Linear Accelerator Center (SLAC) in California, the French National Particle Physics Research Center (IN2P3), the Italian National Institute for Nuclear Physics (INFN).

IHEP's Computing Center

High Energy Physics involves huge amounts of data, and relies on compute-intensive international cooperation. These features greatly promote the development of network and computer technology. In order to meet the computing and storage requirements of high-energy physics, IHEP's Computing Center has been at the frontier of high-performance computing, mass storage systems, high-speed networks and network security research and application for many years. In fact, IHEP is a real pioneer, as it was the first institution with an Internet link in China, the first to start using email, and the first to create its own website. In high performance computing, the Computing Center is committed to using all kinds of advanced distributed computing technologies and platforms for high-energy physics computing services: a 5000 CPU-scale high-performance cluster computing environment, which contributes to the international High Energy Physics Grid Computing initiative LCG, a high throughput data-intensive computing platform. The Computing Centre is also promoting the popular trend of volunteer computing in high energy physics applications through CAS@home. Mass storage in the Computing Centre includes 5PB (PB = Petabyte = 1 million Gigabytes) storage capacity of massive hierarchical storage system CASTOR, the Lustre system with 1.5PB storage scale distributed parallel file system, 300TB (TB = Terabyte = 1000 Gigabytes) of storage capacity DPM mass storage system, 300TB of storage capacity the dCache mass storage systems, in addition to many terabytes of NFS, AFS distributed file system. At present, the Computing Center research team is also actively exploring cloud storage technology, designed to provide more convenient storage for high-energy physicists.

Talk about lousy credit! I've got over 500 hours on the CAS Tsinghua Nano Tech Research app and have only 2 WUs complete successfully. One has paid 1829.50, the other is still pending. WUProp hours can be painful. :P
