What happens when a person is using huge flat database files? Would swap
be good for that? I guessed that Juno was going to use his cluster for
bioinformatics and he might create a "biowulf" cluster. With MPI blast,
even small amounts of memory matter. A computer that only had 1.5 GB of
memory would take 3 times as long as the computers with 2.0. With a
diskless node and a fast ethernet connection, it should be worse.
