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.
