I'm getting the following error when running an open-mpi job on a LSF
cluster using a new version of R 2.15. I didn't get the error message
when running previously using R 2.13. Could anyone point me to the
possible cause, or how to find the offending code? I'm not a sysop,
just a user.
Thanks
Jim
--------------------------------------------------------------------------
An MPI process has executed an operation involving a call to the
"fork()" system call to create a child process. 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: cn159.private.dns.zone (PID 12792)
MPI_COMM_WORLD rank: 7
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.
