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

mkdir failed [1]

Thanks,
