Hi everyone,

Thanks for the help! As Gus pointed out, I could also have found the answer from the FAQ but it might have taken me longer to find.

Yep - sure would. Lots of ways to specify it :-)

you can specify it with OMPI_TMPDIR in your environment, or "-mca orte_tmpdir_base 
<foo>" on your cmd line
Wouldn't --tmpdir=... do the same with `mpirun` for way the latter you 
mentioned?

Hi there,

On a few clusters I am running into an issue where a temporary directory cannot 
be created due to the root filesystem being full, causing mpirun to crash.  
Would it be possible to change the location where this directory is being 
created?

[compute-109-4.local:12055] opal_os_dirpath_create: Error: Unable to create the 
sub-directory (/tmp/openmpi-sessions-leeping@compute-109-4.local_0) of 
(/tmp/openmpi-sessions-leeping@compute-109-4.local_0/28512/0/0), mkdir failed 
[1]

Thanks,
