Dear Open MPI developer, QE is an MPI program, cf. http://qe-forge.org/gf/download/frsrelease/224/1044/qe-6.0.tar.gz
In FFTXlib a questionable source code part is contained which cannot be compiled using version 17 of the Intel compilers and Open MPI; I've condensed it (see attachment).
Note that- using Intel MPI all tested compilers (Intel/GCC/Oracle Studio/PGI) can compile stick_base_TEST.f90 with no errors/warnings issued
- using Open MPI the same is true for GCC/Oracle Studio/PGI;- using Intel compiler up to version 16 and Open MPI, *warnings* like (1) are issued (compilation succeds);
- using Intel compiler /17, *errors* like (2) are issued (compilation fails).- when 'PRIVATE' statement in line #3 removed, also Intel compiler compile the snippet with no error.
Well the questions is - is stick_base_TEST.f90 a correct MPI code? - if YES why does the Intel/17 + OpenMPI combination do not like this? If NO why to hell none of other compiler+MPI combinations complain about this? :o) Have a nice day, Paul Kapinos P.S. Did you noticed also this one? https://www.mail-archive.com/users@lists.open-mpi.org//msg30320.html - 1 --------------------------------------------------------------------------/opt/MPI/openmpi-1.10.4/linux/intel_16.0.2.181/include/mpif-sizeof.h(2254): warning #6738: The type/rank/keyword signature for this specific procedure matches another specific procedure that shares the same generic-name.
