hello Daniele, Could you post the output from ompi_info command? I'm noticing on the RPMS that came with the rhel7.2 distro on one of our systems that it was built to support psm2/hfi-1.
Two things, could you try running applications with mpirun --mca pml ob1 (all the rest of your args) and see if that works? Second, what sort of system are you using? Is this a cluster? If it is, you may want to check whether you have a situation where its an omnipath interconnect and you have the psm2/hfi1 packages installed but for some reason the omnipath HCAs themselves are not active. On one of our omnipath systems the following hfi1 related pms are installed: *hfi*diags-0.8-13.x86_64 *hfi*1-psm-devel-0.7-244.x86_64 lib*hfi*1verbs-0.5-16.el7.x86_64 *hfi*1-psm-0.7-244.x86_64 *hfi*1-firmware-0.9-36.noarch *hfi*1-psm-compat-0.7-244.x86_64 lib*hfi*1verbs-devel-0.5-16.el7.x86_64 *hfi*1-0.11.3.10.0_327.el7.x86_64-245.x86_64 *hfi*1-firmware_debug-0.9-36.noarc *hfi*1-diagtools-sw-0.8-13.x86_64 Howard 2016-12-08 8:45 GMT-07:00 r...@open-mpi.org <r...@open-mpi.org>: > Sounds like something didn’t quite get configured right, or maybe you have > a library installed that isn’t quite setup correctly, or... > > Regardless, we generally advise building from source to avoid such > problems.
