I am able to replicate the issue on a stock Ubuntu 18.04 install with their Open MPI package.
But if I compile my own Open MPI 2.1.1, it works fine. Also, if I compile my own Open MPI 2.1.6, it works fine. I filed a bug at Ubuntu about this: https://bugs.launchpad.net/ubuntu/+source/xubuntu-meta/+bug/1838684 > On Aug 1, 2019, at 2:33 PM, Zhang, Junchao <jczh...@mcs.anl.gov> wrote: > > $ aptitude versions libopenmpi-dev > Package libopenmpi-dev: > i 2.1.1-8 bionic 500 > Package libopenmpi-dev:i386: > p 2.1.1-8 bionic 500 > > $ sudo apt-get install libopenmpi-dev=2.1.6 > Reading package lists...
