I don’t really know where the problem is occurring. The first error message I see is during the step to install mpich commands. I’ve attached all files generated. I assume you are doing this as a normal user and face: mkdir: /Downloads: Permission denied Either execute the install step as root user, or choose a directory in your personal home folder (which would be sufficient in case you use it on your own). -- Reuti > > <m.txt><mi.txt><c.txt>_______________________________________________ > discuss mailing list discuss(a)mpich.org > To manage subscription options or unsubscribe: > https://lists.mpich.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss

By the way, because this isn't Fortran specific, you should be able to build MPICH with PGI Fortran and GCC or Clang to avoid the bug. ~5 years ago there was come issue with building MPICH with CC=gcc and FC=pgifortran related to replacing bcopy/bzero with the equivalent memcpy/memset, but I'm optimistic that problem has disappeared.

I reproduced this with PGI 17.4 community edition on Linux with your Fortran test and an equivalent C one. GDB indicates the SEGV happens here: Program received signal SIGSEGV, Segmentation fault.

However, in my experience, it tends to be somewhat unpredictable whether incorrect code causes a segmentation fault or not. So I thought it worth checking here too. Regards, Andy.

"This occurs with PGI versions 17.1 and 17.5, but not with versions 16.1, 16.5 or 16.7, nor with the current Intel or gcc compilers." It's hard not to conclude this is a PGI 17 bug from your description. Have you reported this to PGI? I would hate for the MPICH team to take support work away from the people PGI pays to do this.

Segmentation fault when MPICH is compiled with Portland compiler 17.5
by Andrew Wood 10 Jul '17

10 Jul '17

Hi, I'm getting a segmentation fault in MPI_INIT, when MPICH is compiled with the current version of the Portland compilers: > mpif90 code.f90 && ./a.out Segmentation fault code.f90 is in the attached .tar.gz file, along with the .log files generated by configuring and building MPICH. This occurs with PGI versions 17.1 and 17.5, but not with versions 16.1, 16.5 or 16.7, nor with the current Intel or gcc compilers. It occurs with MPICH versions 3.1.4, 3.2 and the current master branch in the github repository. The problem does not occur if MPICH is configured with the option '--disable-fast'. Is this a bug in MPICH or PGI, or have I done something else wrong? Thanks, Andy. -- Dr Andrew Wood Fluid Gravity Engineering Ltd. 83 Market Street St Andrews Fife KY16 9NX Tel: +44 (0)1334 460805 Fax: +44 (0)1334 460813 Fluid Gravity Engineering Ltd is registered in the UK with registration number 1674369.
