Re: NFSv4 vs NFSv3 with MPICH2-1.4

[Gregory Magoon <gmagoon@MIT.EDU>]

Unfortunately, I'm not familiar enough with MPICH2 to have an idea about
significant changes between version 1.3 and 1.4, but other evidence suggests
that the version is not the issue and that I would have the same problem with
v1.3.

I'm using the MPICH2 test suite invoked by "make testing" (see below 
for initial
output).

I'm using the nfs-kernel-server and nfs-common Ubuntu packages (natty 
release).

Thanks,
Greg
