Dear MPI users, I am getting the errors below while submitting/executing following script,

Open MPI is currently operating in a condition that could result in memory corruption or other system errors; your MPI job may hang, crash, or produce silent data corruption. The use of fork() (or system() or other calls that create child processes) is strongly discouraged. The process that invoked fork was: Local host: pe38 (PID 80379) MPI_COMM_WORLD rank: 1 If you are *absolutely sure* that your application will successfully and correctly survive a call to fork(), you may disable this warning by setting the mpi_warn_on_fork MCA parameter to 0. -------------------------------------------------------------------------- Is this error fatal or should it be ignored? Thanks Regards, Rizwan
