<pre wrap="">Does this machine have a higher (/different) performance shared file
system such as PVFS or GPFS? We spent some time in november layout out the
filesystem to be sympathetic to GPFS to help avoid bottlenecks like you
are seeing here. It would be kinda sad if either it isn't available or you
aren't using it even though it is available.
