Yes our Beowoulf cluster is already built and in place. It is an Intel/Xenon flavor and we are currently using the Tourque/Maui batch/queuing mechanism. We currently have several modeling codes running on this cluster. I imagine that for now we would have to serve the blastable files from NFS storage via a GigaBit LAN attachement. Items that I am wondering about may include: 1>What is the best version of Blast to run either on one single compute node or many compute nodes at once? 2>Anyone have any direct experience in have a single Beowoulf clusters with both 64 and 32 bit compute nodes? What might be nice to have is several different versions of BLAST locally installed and 32 and 64 bit queues defined for each version. Thanks! Dan PS..Bit offtopic..anyone use the AVAKI datagrid to successfully synchronize the bucketfulls of BLAST datafiles that always seem to accumulate!
