Hi Josh, Thank you for your replying. I tried to patch a Ticket #2139 to openmpi-1.4.1 and to install all of the elements from the very beginning. Then I got a correct work. Probably there are some faults on my environment preparation.
# I cannot reproduce the environment when I got failure. # I'm very sorry that I cannot find truly factors of this malfunction # and cannot send any information. # Now I use openmpi-1.4.2, it works well without any patch. (except for ompi_info) >> In addition, when I confirmed open_info output as your demo movie, I got >> "MCA crs: none (MCA v2.0, API v2.0, Component v1.4.1)" (open_info.output) > > This is actually a known bug with ompi_info. I have a fix in the works for > it, and should be available soon. Until then the ticket is linked below: > https://svn.open-mpi.org/trac/ompi/ticket/2097 Thank you, I'll try it.
