The STAR experiment, in collaboration with the NERSC Scientific Data Management Group is prototyping / developing an approach to accomplish a high bandwidth data analysis capability using commodity components in a fault tolerant fashion. The prototype hardware consists of two small clusters of linux nodes (about 10 dual-CPU nodes), a few 100 GB local disk on each node. One cluster is at the RCF at Brookhaven and the other at PDSF at LBNL/NERSC. The local disk on each node is not exported on the network so that all processing of data occurs on processors with locally attached disk.
