Thanks for looking at this Jeff. No, I cannot use mpirun to launch a non-MPI application. The command "mpirun -np 2 hostname" also hangs.
I get the following output if I add the -d command before (I've replaced the server with the hashtags) : [scotts-mbp.3500.dhcp.###:05469] procdir: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469/0/0 [scotts-mbp.3500.dhcp.###:05469] jobdir: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469/0 [scotts-mbp.3500.dhcp.###:05469] top: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469 [scotts-mbp.3500.dhcp.###:05469] top: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501 [scotts-mbp.3500.dhcp.###:05469] tmp: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T/ [scotts-mbp.3500.dhcp.###:05469] sess_dir_cleanup: job session dir does not exist [scotts-mbp.3500.dhcp.###:05469] sess_dir_cleanup: top session dir not empty - leaving [scotts-mbp.3500.dhcp.###:05469] procdir: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469/0/0 [scotts-mbp.3500.dhcp.###:05469] jobdir: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469/0 [scotts-mbp.3500.dhcp.###:05469] top: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501/pid.5469 [scotts-mbp.3500.dhcp.###:05469] top: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T//ompi.scotts-mbp.501 [scotts-mbp.3500.dhcp.###:05469] tmp: /var/folders/l0/94hsdtwj09xd62d90nfh_3h00000gn/T/ [scotts-mbp.3500.dhcp.###:05469] [[48286,0],0] Releasing job data for [INVALID] Can you recommend a way to find where mpirun gets stuck?
