[mvapich-discuss] Segmentation fault when compiling with Intel 15, mvapich2 2.1, and openmp

[Craig Tierney - NOAA Affiliate]

Hello,

I am having a problem building and running codes with Intel 15.X and
Mvapich2 2.1 that use openmp.  The following code shows the problem:

program test
    use mpi
    integer :: ierr, iprov
    real(8) :: a
    call mpi_init_thread(MPI_THREAD_FUNNELED,iprov,ierr)
    call random_number(a)
    write(*,*)"hello"
    call mpi_finalize(ierr)
end program test

If this is compiled as:

# mpif90 -openmp -O3 test.f90 -o test

And run, the following error message is generated.

# mpiexec.hydra -np 2 ./testmpifort

===================================================================================

===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault
(signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

When you get the stack trace, you see:

(gdb) bt
#0  0x000000000040b0c4 in init_resource ()
#1  0x000000000040b02a in reentrancy_init ()
#2  0x000000000040af48 in for__reentrancy_init ()
#3  0x00002aaaab329115 in for_rtl_init_ () from
/home/admin/software/apps/mvapich2/2.1-intel/lib/libmpi.so.12
#4  0x0000000000403249 in main ()

Intel believes this is a mvapich2 issue, not a compiler issue.
