[mpich-discuss] shared memory mmap file

[Dustin Sorge]

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
