[Ocfs2-test-devel] [PATCH 1/2] Ocfs2-test: Truncate redundant openmpi mca args from mpirun.

[Tristan Ye]

We need to explicitly specify '-mca btl_tcp_if_include eth0' argument before,
to pass a public vif for communcation between mpi hosts due to a openmpi bug
in former versions, now it seems has been solved, we therefore truncate such
redundant and unreadable arguments from openmpi_run.
