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. thanks very much, -Dustin On Mon, Feb 4, 2013 at 11:54 AM, Jim Dinan <[email protected]> wrote:
Hi Dustin,
AFAICT, we don't provide a way to change the filename, apart from editing src/util/wrappers/mpiu_shm_**wrappers.h:590. Is this something that you need to get MPICH working on your system? Would an environment variable work, or do you need to set this up at compile time?
Cheers, ~Jim.

Hello everyone, I was wondering if it is possible to have the shared memory mmap'ed file be in a different location other than /dev/shm or /tmp. Is there an environment variable I can specify?
I am using MPICH2 and have configured it like this:
./configure --prefix=/opt/mpich2 --with-device=ch3:nemesis --with-shared-memory=mmap --enable-nemesis-shm-**collectives
Is this configuration sufficient for MPICH2 to use the shared memory file?
thanks very much, -Dustin
