[PETSC #16590] PETSc on Dual Opteron Cluster

[amjad ali]

Hello Matt...

1) configure.log attached

2) Yes, I am online.

3) At the moment I want to develop & run PARALLEL codes on my FC6 Desktop
(single machine). Should I use the option --download-mpich=1 or
--download-mpich=0

regards,
Amjad Ali.
