During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.

adios_reorganize hangs when launched in MPMD mode

Created by: keichi

adios_reorganize hangs when launched with other applications (heatTransfer, gray-scott, etc.) in MPMD mode. For example, the following hangs:

mpirun -n 4 build/gray-scott simulation/settings-staging.json : \
       -n 1 adios_reorganize gs.bp reorg.bp SST '' BP4 '' 1

This is needed for the JAXA use case and worked fine in the past.
