[maker-devel] Maker Execution Error

[Atkins, Jacqueline (NIH/NIAID) [C]]

Hello,

I have recently installed Maker on RHEL 7/ Perl-5.16.3.  When I attempt to execute, I get the following error

$ mpiexec -n 4 maker -help


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:          submit (PID 316)

  MPI_COMM_WORLD rank: 2


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.

--------------------------------------------------------------------------

[submit:122878] 3 more processes have sent help message help-mpi-runtime.txt / mpi_init:warn-fork

[submit:122878] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages

[submit bin]$  mpiexec --version

mpiexec (OpenRTE) 1.8.4


I have a previous version of Maker installed that is using OpenMPI 1.3.3 and it is working fine.  I was wondering if you think this might be related to the version of OpenMPI?

Thank you in advance.
Jackie
