osc/pt2pt: workaround for issue 2614 for v2.0.2
As a workaround for issue open-mpi#2614 for the v2.0.2 release, do not allow for selection of the OSC PT2PT when creating an MPI RMA window. Print a hopefully helpful message and return an not-supported error. This PR should be reverted once a fix for open-mpi#2614 is in place. Signed-off-by: Howard Pritchard <howardp@lanl.gov> (cherry picked from commit d0ffd66) The original commit message is shown above. Followup: as of this writing (26 Mar 2018), we do not plan to fix this issue for the v2.0.x or v2.x. Hence, the osc/pt2pt component will continue to disable itself in THREAD_MULTIPLE scenarios for the life of all v2.x series. It is possible (likely?) that this will be fixed in a v3.0.x release (where x>1).

The OSC pt2pt component does not support MPI_THREAD_MULTIPLE in this release. | ||
Workarounds are to run on a single node, or to use a system with an RDMA | ||
capable network such as Infiniband. |
