I have an application that was built and ran with OpenMPI 1.7.5 on Mac OS X 10.11.6 without problems. I just switched to OpenMPI 1.10.6 and built the application. It built without problems. However, when I ran it (I just want to run on my machine) like the following
> ~/OpenMPIPrj/imports/lib/openmpi/1.10.6/bin/mpirun -np 4 ./myapp It gives the following errors 4 times. ------------------------------------------------------------ A process or daemon was unable to complete a TCP connection to another process: Local host: mymacname Remote host: xx.xxx.xxx.xxx This is usually caused by a firewall on the remote host. Please check that any firewall (e.g., iptables) has been disabled and try again. ----------------------------------------------- The xx.xxx.xxx.xxx is the ip address of my Mac. I checked my Mac. The sys prefs->Security->Firewall. It says Firewall::Off. And I can run > ~/OpenMPIPrj/imports/lib/openmpi/1.10.6/bin/mpirun -np 4 uname –n without problems.
