I am using Open MPI 4.0.1
Once fully setup, I intend to run my application in conjunction with grid, so
the resources will be allocated by grid. This makes it very difficult to
specify IP address for btl_tcp_if_include.
For the named exclude interfaces, it st
You might want to make sure that the run time is working properly before going

If that works, then try mpirun'ing the "hello world" example program that comes
in the ex
