I am a
member of the grid and the user support teams at LRZ. We operate a 9728 core
SGI Altix 4700 and a heterogeneous Linux-Cluster with 800 cores. Together
with the MPG a cluster with 800 cores and 350 TB disc space is part of LCG
as a Tier-2 Center. In addition to LCG, LRZ is also a member of the DEISA/eDEISA
grid infrastructure. My work involves porting of applications to different
platforms, optimization, debugging and grid enablement, which is currently
limited to DEISA but should be expanded to LCG as well.
