Hi, Thank you for the guidance. I rebooted my computer but now the program fails to compile.
I then tried changing the tmp directory adding the following line to *openmpi-mca-params.conf*: *orte_tmpdir_base = "/Users/myname/Desktop/shared/tmp"* But now I get the following error: *PMIX ERROR: ERROR in file dstore_base.c at line 1659* *Impossible to open the file /"Users/myname/Desktop/shared/tmp"/ompi.dyn900-158.501/pid.1610/contact.txt in write mode* *ORTE_ERROR_LOG: File open failure in file util/hnp_contact.c at line 91* *CANNOT CREATE FIFO /"Users/myname/Desktop/shared/tmp"/ompi.dyn900-158.501/pid.1610/0/debugger_attach_fifo: errno 2* Is there a way I can fix this? Thanks!
