Package: libopenmpi3 Version: 3.1.2-5 Severity: normal Dear Maintainer,
I updated Open MPI and libpmix2 on my Sid X86_64 system this afternoon: Open MPI 3.1.2-5 libpmix2 3.0.2-2 My simple MPI tests run to completion and give correct results, but there is an abnormal delay in startup and new warning messages. Example: INFO: Executing build/mpi_mm_c mpiexec -np 2 build/mpi_mm_c < mpi_mm_c.in > mpi_mm_c.tmp 2>mpi_mm_c.err ron5sid.10482hfi_wait_for_device: The /dev/hfi1_0 device failed to appear after 15.0 seconds: Connection timed out ron5sid.10483hfi_wait_for_device: The /dev/hfi1_0 device failed to appear after 15.0 seconds: Connection timed out mpi_mm has started with 2 tasks. ... (rest of results are normal) I did some research online. Red Hat Bug 1408316 from a couple years ago was to fix libfabric 1.4.1 in RHEL7 to not wait for /dev/hfi* devices if OPA/HFI hardware is not present. Occurred when system had PSM2 installed but no OPA/HFI hardware. My system does have libfabric1-1.6.1-5, which libopenmpi3 depends on. My system does have libpsm-infinipath1 and libpsm2-2, which libopenmpi3 depends on. I noticed this note in the "Changes" for openmpi 3.1.2-5: "* Drop link-libfabric.patch as obsolete" Relevant? What did the obsolete patch do? I see in my test results that my MPI tests passed 12 Sep 2018, when 3.1.2-2 or 3.1.2-3 was current. I don't see any record of testing 3.1.2-4. I'm filing this as "normal" severity, since my programs do run correctly. It's a slight practical nuisance as my test jobs flag changed output as possible problems.
