Gilles,
Thank you for your fast reply. When I type whereis mpifort I have the following: *mpifort: /usr/bin/mpifort.openmpi /usr/bin/mpifort /usr/share/man/man1/mpifort.1.gz* I made sure I exported the LD_LIBRARY_PATH after I prepended /usr/lib/openmpi/lib. The same error is produced. If I type ldd ./test I get the following: * linux-vdso.so.1 => (0x00007ffde08ef000) libmpi_mpifh.so.12 => /usr/lib/libmpi_mpifh.so.12 (0x00002b5a2132c000) libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00002b5a21585000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00002b5a218b0000) libmpi.so.12 => /opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/intel64/lib/libmpi.so.12 (0x00002b5a21c7a000) libopen-pal.so.13 => /usr/lib/libopen-pal.so.13 (0x00002b5a2243c000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00002b5a226d9000) libquadmath.so.0 => /usr/lib/x86_64-linux-gnu/libquadmath.so.0 (0x00002b5a228f7000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00002b5a22b36000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00002b5a22e3f000) /lib64/ld-linux-x86-64.so.2 (0x000055689175a000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00002b5a23056000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00002b5a2325e000) libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00002b5a23462000) libhwloc.so.5 => /usr/lib/x86_64-linux-gnu/libhwloc.so.5 (0x00002b5a23666000) libnuma.so.1 => /usr/lib/x86_64-linux-gnu/libnuma.so.1 (0x00002b5a238a0000) libltdl.so.7 => /usr/lib/x86_64-linux-gnu/libltdl.so.7 (0x00002b5a23aac000)* Thanks.
