I'm testing out rebuilding packages with openmpi 3.1 in COPR:
https://copr.fedorainfracloud.org/coprs/g/scitech/openmpi3.1/builds/
A number of packages are failing running tests only on Fedora Rawhide
x86_64 with processes killed with signal 4 (Illegal instruction). For
example:
+
PYTHONPATH=/builddir/build/BUILDROOT/mpi4py-3.0.0-6.git39ca78422646.fc30.x86_64/usr/lib64/python2.7/site-packages/openmpi
+ mpiexec -n 1 python2 test/runtests.py -v --no-builddir
--thread-level=serialized -e spawn
BUILDSTDERR:
--------------------------------------------------------------------------
BUILDSTDERR: Primary job terminated normally, but 1 process returned
BUILDSTDERR: a non-zero exit code. Per user-direction, the job has been
aborted.
BUILDSTDERR:
--------------------------------------------------------------------------
BUILDSTDERR:
--------------------------------------------------------------------------
BUILDSTDERR: mpiexec noticed that process rank 0 with PID 0 on node
656ae442c6bf45fe9b45c5481f41bc45 exited on signal 4 (Illegal instruction).
BUILDSTDERR:
--------------------------------------------------------------------------
Unfortunately I have been unable to reproduce this in any local mock
builds. So I'm left wondering if this is some kind of peculiarity with
the COPR builders or if there is a real problem with openmpi. Any
suggestions for how to further debug this would be greatly appreciated.
(PID 0 seems very odd)
