Hi Michael,

Do you recommend installing MPICH2 and then install PVFS2 over it ?
But then the PVFS2 guide says I need to add the option --with-pvfs2 while
configuring MPICH2.
Is my understanding on this point correct ? I install PVFS2, then while
installing MPICH2, I add the option
./configure --with-prefix=<path of the PVFS2>
