Dear developers, also the following issue is defintely raised by a misconfiguration of Open MPI, SIGSEGV's in 'ompi_info' isn'n a good thing, thus this one mail. Just call: $ export OMPI_MCA_mtl="^tcp,^ib" $ ompi_info --param all all --level 9 ... and take a look at the below core dump of

Hi, The following mpifort command fails with a syntax error. It seems that the code is compatible with old gfortran, but I am not aware of that. Any idea about that? mpifort -ffree-form -ffree-line-length-0 -ff2c -fno-second-underscore -I/opt/fftw-3.3.5/include -O3 -c xml.f90 xml.F:641.46:

Re: [OMPI users] An old code compatibility

Remember that mpifort is just a wrapper over your underlying fortran compiler. If your fortran compiler can't compile your Fortran code, then neither can mpifort. You can use the "--showme" option to mpifort to show you the command line that it is invoking under the coverts. E.g.:

Re: [OMPI users] Valgrind errors related to MPI_Win_allocate_shared
