Dr Andreas Gellrich (DESY)


DESY is one of the world-wide leading centers for research with particle accelerators and synchrotron light. In HEP DESY participates in LHC as a Tier-2 center, supports on-going analyzes of HERA data, is a leading partner for ILC, and runs the National Analysis Facility (NAF) for LHC and ILC. For the research with synchrotron light major new facilities are operated and built (FLASH, PETRA III, and XFEL). DESY is facing steadily growing computing demands of various e-science communities with very different requirements and use cases as well as computing strategies and traditions. In HEP, collaborative work in a global context is well established since long whereas the synchrotron light experiments are just entering the transition region from purely local to mostly global computing approaches with huge amounts of data. I order to meet the requirements, a robust and scalable computing infrastructure is needed which is based on well-defined open standards and protocols - the Grid. In the context of EU-project EGEE and the national Grid initiative D-GRID DESY operates one common gLite Grid infrastructure with currently about 1500 CPU cores and a few hundred Terabytes of disk space, and tape. In the contribution to CHEP'09 we will in depth discuss the conceptional and operational aspects of our multi-VO and multi-community Grid infrastructure. This includes in particular the means for authorization, efficient and fair share of resources, and accounting.
