Dear All, Some time ago there was a discussion on this list regarding enabling CMA support in OpenMPI. There were 2 positive votes
http://www.open-mpi.org/community/lists/devel/2012/01/10208.php I have checked the latest releases today and haven't seen any trace of CMA support. Since CMA is available from kernel 3.2 and in RHEL 6.3 and above maybe it would be worth to consider adding this feature? Is there any reason for not including the patch yet? Best Regards -- Lukasz Flis
