The question is if we should do as MXM wants, or ignore it? Has anyone an experience running recent OpenMPI with MXM enabled, and what kind of ulimits do you have? Any suggestions/comments appreciated, thanks!
It should be sufficient to set the limits to the amount of real memory your cluster nodes have (i.e. if you have 64GiB), just limit both heap and stack to 64GiB.
This way you don't run out of address space for mappings. Regards, Thomas
