I mean no slight of SSC users or admins, but to me this sounds like
some sort of mistake. temperatures, bad cables, etc. our largest
myrinet cluster is 287 nodes, versus ~512 for SSC's cluster, but we
do have a greater number of total ports. I guess it's conceivable
that SSC's problem is specific to their very large switch...
