I can get MPICH working without it, however I am doing some NFS testing and having that file mounted over NFS would be a very interesting use case for me. I would like to avoid mounting /tmp over NFS so i wanted to see if there was a way to specifying another path for the file.
You probably don't want to be accessing this file directly, and especially not over NFS. The only reason a file exists is as a way for all processes to map the same memory. IIRC the file should actually be unlinked (deleted) as soon as all processes on the node have mmap-ed it. Can you explain more about what you are actually trying to accomplish? -Dave
