It looks like the issue is because the Ubuntu package is compiled with `--enable-heterogeneous` (this is not a default option). Specifically: if I compile Open MPI 2.1.1 with `--enable-heterogeneous`, I am able to replicate the issue.
It further looks like we elected not to fix this issue upstream in the v2.x series; only the v3.x series has the fix. I would advise the Ubuntu package to: 1. Do not use `--enable-heterogeneous` (it's not common usage, anyway). 2. Upgrade to Open MPI v2.1.6 (for ABI compatibility with the already-shipping openmpi-dev-2.1.1-8). If you don't care about ABI, upgrade to whatever the latest version is on www.open-mpi.org. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838684 Title: Open MPI 2.1.1 sample code failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/1838684/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
