Adding MCS algorithm-based implementation for shmem_locks to improve performance for large scale SHMEM applications using locks. MCS lock is now the default algorithm, use the following MCA parameter to disable. --mca oshmem_enable_mcs_lock 0 to disable mcs locks and revert to default ticket locking. --mca oshmem_api_verbose 10 for debug information on shmem_locks. Signed-off-by: Vishwanath Venkatesan <vvenkatesan@nvidia.com> (cherry picked from commit 1396585)
