Error in Parallel Execution using OpenMPI


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?


It is very difficult to know what the problem might be without any other information. What kind of code are you trying to run?
