Tree-based launch in Open MPI (part 2)
In my prior blog entry, I described the basics of Open MPI’s tree-based launching system over ssh (yes, there are still some valid / good reasons for using ssh over a native job scheduler / resource manager’s parallel launch mechanisms…). That entry got a little long, so I split the rest of the discussion into […]
