errors when running example scripts for HOOMD-Blue

[sanjibpaul88]

Hi,

I was running the example scripts for HOOMD-Blue umbrella sampling and I am getting the following error.

******ubuntu-20.04.4.sif I have no name!@cs001 HOOMD]$ mpiexec --mca btl self -np 12 /path-to-SSAGES/ssages multiwalker_umbrella_input.json

MPI_ABORT was invoked on rank 6 in communicator MPI_COMM_WORLD
with errorcode -1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.******

Can I please know how I can resolve this? Please let me know if I need to provide anything else regarding this.

Thanking you,

There's a problem specific to HOOMD-blue v2.9.3 that causes this error. The easiest fix is using another HOOMD-blue version. Versions v2.6.0 to v2.9.7 (except for v2.9.3) are compatible with SSAGES 0.9.3.
