A system call failed during shared memory initialization that should
not have. It is likely that your MPI job will now either abort or
experience performance degradation.

Randy, try what is recommended here:
https://github.com/SENSEI-insitu/SENSEI/issues/126
Well, I don't have the problem when I compile and run locally. I don't think this is something we should expect users to need to do.
I am not getting the error because for me MacOS automatically defined a TMPDIR environment variable as follows:
echo $TMPDIR
/var/folders/qq/nhw6cyzs2fdf_3bms4st1k9r002c63/T/
