The openib BTL and BLCR support in Open MPI were working about a year ago (when I last checked). The psm BTL is not supported at the moment though.
I'm trying to build openmpi with support for BLCR plus qlogic infiniband (plus grid engine). Everything seems to compile OK and checkpoints are taken but whenever I try to restore a checkpoint I get the following error:- do_mmap(<file>, 00002aaab18c7000, 0000000000001000, ...) failed: ffffffffffffffea- mmap failed: /dev/ipath- thaw_threads returned error, aborting. -22- thaw_threads returned error, aborting. -22Restart failed: Invalid argumentThis occurs whether I specify psm or openib as the btl.This looks like the sort of thing I would expect to be handled by the blcr supporting code in openmpi. So I guess I have a couple ofquestions.1)Are Infiniband and BLCR support in openmpi compatible?2)Are there any special tricks necessary to get them working together.
