The use of fork() (or system() or other calls that create child processes) is strongly discouraged. The process that invoked fork was: Local host: n401 (PID 114242) MPI_COMM_WORLD rank: 0 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. -------------------------------------------------------------------------- R version 3.3.2 (2016-10-...
