To run an X10 program on the local machine using the C++ backend and OpenMPI, it is necessary to create a Remote connection (as OpenMPI is not a supported option for a Local connection).
I created an OpenMPI Remote connection for local host using password-based authentication. On selecting Validate Configuration, I received the following error:
Checking afterwards, the directory /tmp/x10-validation-josh-01-09-19 does not exist.
My x10_platform.conf is attached.
