RE: communication pattern causes corrupted data

CPlant/NM may have seen some corruption, I dont know.  We don't use their
modified glibc, though, so that won't be the issue.  Our distro is stock RH
7.1 at the core.

Do you have any alpha's to test with?

I too did 24 hours of non-stop runs on 16 processors (about half on 16
dedicated nodes of 1 proc each, and half on 8 nodes using both procs)
on:

    x86:  gm-1.5.1 mpich-1.2.4..8a
    ia64: gm-1.6.3 mpich-1.2.4..8a

Compiled with gcc -g.  Both never caused errors using input.final.0.

Didn't the CPlant/NM guys have a similar issue with corruption on alpha
that ended up being a glibc issue?  I could be misremembering, but you
might ask Ron.
