The PESSL_ERROR_SYNC environment variable allows you to enable and disable error synchronization. If error synchronization is disabled, the first process containing input-argument error(s) to finish computing, issues its error message(s) and terminates Parallel ESSL processing on all processes. Therefore, you should only disable error synchronization when your application program is debugged.
PESSL_ERROR_SYNC=no
-or-
PESSL_ERROR_SYNC=NO
export PESSL_ERROR_SYNC
This causes Parallel ESSL to disable error synchronization in all calls to the Parallel ESSL subroutines.
If you do not set the environment variable or you set something other than 'no' or 'NO', Parallel ESSL uses error synchronization in all calls to the Parallel ESSL subroutines.
