error in cosmomc

[moslem zarei]

Hi
I am working with the latest version of cosmomc. After running over 4 node, at the end I find the following error:

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1763734121.

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 you tell me what does mean this message?

Thank you very much

Probably that you are trying to estimate the covariance matrix and it didn't work. Turn off that option and just run chains directly (with MPI learning options on).

Thank you for the reply. This option works but it takes more time.
