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. -22 Restart failed: Invalid argument
This 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.
