Paul - Any chance you could grab a stack trace from the mpi app? That's probably the fastest next step
Brian Sent with Good (www.good.com) -----Original Message----- From: Paul Hargrove [phhargr...@lbl.gov<mailto:phhargr...@lbl.gov>] Sent: Friday, December 20, 2013 03:33 PM Mountain Standard Time To: Open MPI Developers Subject: [EXTERNAL] [OMPI devel] 1.7.4rc2r30031 - OpenBSD-5 mpirun hangs With plenty of help from Jeff and Ralph's bug fixes in the past 24 hours, I can now build OMPI for NetBSD. However, running even a simple example fails: Having set PATH and LD_LIBARY_PATH: $ mpirun -np 1 examples/ring_c just hangs Output from "top" shows idle procs: PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND 31841 phargrov 10 0 2140K 3960K sleep/1 nanosle 0:00 0.00% ring_c 13490 phargrov 2 0 2540K 4892K sleep/1 poll 0:00 0.00% orterun Distrusting then env vars and relying instead on the auto-prefix behavior: $ /home/phargrov/OMPI/openmpi-1.7-latest-openbsd5-amd64/INST/bin/mpirun -np 1 examples/ring_c also hangs Not sure exactly what to infer from this, but a "bogus" btl doesn't produce any complaint, which may indicate how far startup got: $ mpirun -mca btl bogus -np 1 examples/ring_c Still hangs, and no complaint about the blt selection All three cases above are singleton (-np 1) runs, but the behavior with "-np 2" is the same. This does NOT appear to be an ORTE problem: -bash-4.2$ orterun -np 1 date Fri Dec 20 14:11:42 PST 2013 -bash-4.2$ orterun -np 2 date Fri Dec 20 14:11:45 PST 2013 Fri Dec 20 14:11:45 PST 2013 Let me know what sort of verbose mca parameters to set and I'll collect the info. Compressed output of "ompi_info --all" is attached. -Paul -- Paul H.
