Wow, just found this bug. I am one of the upstream Open MPI developers; we just had this exact issue reported to us, and I reported it in https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/1838684. I guess I'll go mark that one as a duplicate of this one.
The fix for this issue is very, very simple -- someone just needs to fix Ubuntu's recipe for building Open MPI to *not* include --enable- heterogeneous. We'd also strongly suggest that Ubuntu at least upgrade to the latest Open MPI 2.1.x (which is 2.1.6, at the time of this writing). There are later series available (we're up to Open MPI v4.0.x these days), but Open MPI v2.1.6 is ABI compatible with the already-shipping-in-Ubuntu Open MPI v2.1.1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731938 Title: Invalid results with OpenMPI because of --enable-heterogeneous To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/1731938/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
