Uses an application that reads in a huge file of records, each a genome sequence, and compares each sequence against a given sequence. Looks at cache performance, message latency, cost of prefetches and directory reads, and throughput. He tries one-disk, one-proc transfer rates. Because of contention with the directory server on one of the two I/O nodes, it was faster to put all of the file on the other I/O node. Striping is good for multiple readers. Best access pattern was interleaved, not segmented or separate files, because it avoided disk seeks. Perhaps the files are stored contiguously? Can get good speedup by reading the sequences in big integral record sizes, from CFS, using a load-balancing scheduled by the host. Contention for directory blocks -- through single-node directory server.} }
