Openmpi There Are Not Enough Slots Available In The System
Package: openmpi-bin;Maintainer for openmpi-bin is Alastair McKinstry <mckinstry@debian.org>; Source for openmpi-bin is src:openmpi (PTS, buildd, popcon).
If more processes are requested than cores are available an error will be thrown: There are not enough slots available in the system. On WINDOWS this can be if hyperthreading is active. A system physically having 4 CPUs (cores), would show 8 CPUs in case of hyperthreading. What version of Open MPI are you using? (e.g., v1.10.3, v2.1.0, git branch name and hash, etc.) V4.0.0. Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.) It was installed from source/distribution tarball. Please describe the system on which you.
Hello, This appears to be related to a known issue rep: openmpi and tests attempting to spawn more processes than there are processors available (as you correctly identify). There are not enough slots available in the system to satisfy the 4 slots. Looks like openmpi 3.1.3 hasn't been packaged for Ubuntu 18.04, so I'll have to build.
