Hi all,
I am not really sure whether this is an intel or ompi bug?
I have now tried with all 1.10.* versions (including 1.10.1rc[23]) to test
whether this could be circumvented.
I use the intel 2016.1.0.423501 compiler.
I can successfully compile OpenMPI and use the C-compiler. But as soon as I
compile the most simple fortran (ping-pong) program with mpif90 (no compile
flags) I get symbol lookup errors.
$> mpirun -np <> <exec>
intel: symbol lookup error:
*/XeonX5550/openmpi/1.10.1/intel-16.0.0/lib/libmpi_mpifh.so.12: undefined
symbol: mpi_fortran_argvs_null__
So I thought that it was really a missing symbol, hence I grepped for the
routine in the libraries:
for m in *.a *.so
do
echo $m
nm $m | grep mpi_fortran_argv
done
And came up with:
libopen-trace-format.a
libotfaux.a
libvt.a
libvt-hyb.a
libvt-mpi.a
libvt-mpi-unify.a
libvt-mt.a
libvt-pomp.a
libmca_common_sm.so
libmca_common_verbs.so
libmpi_cxx.so
libmpi_mpifh.so
U mpi_fortran_argv_null
U mpi_fortran_argv_null_
U mpi_fortran_argv_null__
U mpi_fortran_argvs_null
U mpi_fortran_argvs_null_
U mpi_fortran_argvs_null__
U ompi_fortran_argv_f2c
libmpi.so

00000000002a8500 B mpi_fortran_argv_null_
00000000002a8560 B mpi_fortran_argvs_null_

liboshmem.so
0000000000356e60 B mpi_fortran_argv_null
0000000000356d00 B mpi_fortran_argv_null_

0000000000356f20 B mpi_fortran_argvs_null_
0000000000356ca0 B mpi_fortran_argvs_null__
libotfaux.so
libvt-hyb.so
libvt-mpi.so
libvt-mpi-unify.so
libvt-mt.so
libvt.so
So they are uninitialized in the common section of mpi.so, but undefined in
mpi_mpifh.so.
Note:
I have also tried with intel 15 and ompi 1.8.X and the symbol tables are
identical yet the program executes fine.
Note:
I then tried with gcc (5.2.0) and found the exact same nm listings, i.e.
the mpi_fortran_argvs_null routine are all B/U defined in the libraries.
Yet, the program runs fine.
I have tried manually setting the -l order to
-lmpi_mpifh -lmpi
to no avail.
Should this be reported to intel? Or?
