[Bug 232036] Re: importing petsc4py.PETSc results in segfault
This is a bug in OpenMPI and I also came across it. Workaround for
python is quite simple :
from ctypes import *
mpi = CDLL('libmpi.so.0', RTLD_GLOBAL)
proposed in OpenMPI FAQ at http://www.open-mpi.org/faq/?category=running
#loading-libmpi-dynamically
If I recoll correctly, I didn't observe this behaviour previously (in
8.10) with OpenMPI 1.2 series.
My guess is that this bug should be attached to libopenmpi

The real cause is bug #260027 (though that's hard to guess, so I did not mark it as a duplicate). -- importing petsc4py.PETSc results in segfault https://bugs.launchpad.net/bugs/232036 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
