I'm trying to debug a crash in openmpi on the armv7hl builders:
Open MPI tried to bind a new process, but something went wrong. The
process was killed without launching the target application. Your job
will now abort.
Local host: arm02-builder01
Application name: ./tst_parallel4
Error message: hwloc_set_cpubind returned "Error" for bitmap
"0-3" Location: odls_default_module.c:551
I can't reproduce it on my local armv7hl qemu VM as it appears to be
coupled to the actual topology of the machine.
Is it possible to install debuginfo packages into the buildroot
somehow?
Not really.
Anyone have any other suggestions for debugging?
Maybe I can test via the openmpi package somehow...
Yes, use
arm03-packager00.cloud.fedoraproject.org (or
arm03-packager01.cloud.fedoraproject.org) and try and duplicate in a
mock chroot there? They are both running f21 (the same as the
builders) on the same hardware make/model as the builders.
