<div dir="ltr">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. <div>

AFAICT, we don't provide a way to change the filename, apart from editing src/util/wrappers/mpiu_shm_<u></u>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?<br>

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