_MAC From: users [mailto:users-boun...@lists.open-mpi.org] On Behalf Of Howard Pritchard Sent: Thursday, December 08, 2016 9:23 AM To: Open MPI Users <users@lists.open-mpi.org> Subject: Re: [OMPI users] device failed to appear .. Connection timed out 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: hfidiags-0.8-13.x86_64 hfi1-psm-devel-0.7-244.x86_64 libhfi1verbs-0.5-16.el7.x86_64 hfi1-psm-0.7-244.x86_64 hfi1-firmware-0.9-36.noarch hfi1-psm-compat-0.7-244.x86_64 libhfi1verbs-devel-0.5-16.el7.x86_64 hfi1-0.11.3.10.0_327.el7.x86_64-245.x86_64 hfi1-firmware_debug-0.9-36.noarc hfi1-diagtools-sw-0.8-13.x86_64 Howard 2016-12-08 8:45 GMT-07:00 r...@open-mpi.org<mailto:r...@open-mpi.org> <r...@open-mpi.org<mailto: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. Is there some reason not to just do so?

Anyway, /dev/hfi1_0 doesn't exist. If I use an OpenMPI version compiled from source I have no issue (gcc 4.8.5). many thanks in advance. cheers Daniele _______________________________________________ users mailing list users@lists.open-mpi.org<mailto:users@lists.open-mpi.org> https://rfd.newmexicoconsortium.org/mailman/listinfo/users _______________________________________________ users mailing list users@lists.open-mpi.org<mailto:users@lists.open-mpi.org> https://rfd.newmexicoconsortium.org/mailman/listinfo/users
