Hi,
I am trying to run a custom application in Palabos and carrying out parallel execution using OpenMPI. The program works when I do not use parallel execution, but when I do use it, the program crashes with the following error message:
*** An error occurred in MPI_Bcast
*** reported by process [47464361492481,3]
*** on communicator MPI_COMM_WORLD
*** MPI_ERR_TRUNCATE: message truncated
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort and potentially your MPI job)
Could someone please help me out with a diagnosis and/or a fix for this?
TIA.
