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>
