Description
The Institute of High Energy Physics (IHEP) is the biggest and comprehensive
fundamental research center in China. Particle physics is one of the most
important research fields at IHEP. This presentation will give a brief
introduction to the currently running experiments as well as the experiments
being constructed. With accumulation of experimental data, growing needs of
computing resources put great pressure on the limited local resources. To
meet the challenge, the BESIII Grid computing system was developed based on
the Dirac middleware. After years' successful running, it proved to be an
effective solution for integrating computing resources dispersed in the
collaboration members. Further work has been done to extend its support for
multiple experiments with a single system setup. This presentation will also
cover the development of cloud computing platform for both scientific
computing and information services at IHEP. The feature of dynamic
allocation of computing resources makes it possible to improve the overall
efficiency of resource usage. Recently, a proposal of setting up a dedicated
HPC facility has been raised by a couple of experiments to speed up the
CPU-intensive simulation and analysis work. This presentation will discuss
the possibility of integrating the future HPC facility with the current
system.
