Use ABORT instead of STOP! #20

ERROR Messaging in WABBIT

Please avoid using the stop command! Using stop instead of MPI_abortcan leave some processes on the computation nodes, without aborting them. If you see it in any of the modules replace it by one of the following routines (use module_globals):

call abort( <some ID>, <your error message>) call abort( <your error message>) call abort( <some ID>)

Example: call abort(10092018, "Error: this is my error message")

This routine is a wrapper for MPI_ABORT, which is awesome because your module does not need to know the MPI Communicator or any other extra variable needed for error messaging.

No stop routine left in code
