Well, as Jeff said, the only safe way to run NFS servers for ROMIO is
by dis
Bummer. I know there's some kind of issue with the "noac" NFS value
(no attribute caching; when I enabled that on my cluster, my entire
cluster got veeeryyy slowww with regards to NFS).
We unfortunately don't have much ROMIO expertise here on the OMPI
list; we pretty much import it
I wrote a code the other day to MPI IO to write files, and OpenMPI/ROMIO
seems to be having problems with the NFS server. I have read that NFSv4
and ROMIO don't perform very well together, but my problem is probably a
misconfiguration of some kind. Basically when I use MPI IO to write a
file on an
