Good Day All, We’re trying to get a build of 3.2 for our centos7 hpc environment using IB. we don’t have mxm installed so I’m trying this: ./configure --prefix=/software/tools/apps/mpich/gnu/3.2 --with-pm=hydra -with-device=ch3:nemesis --with-ibverbs=/usr --with-pbs=/opt/torque But we end up with backtraces of the form: mpi_script_launcher.run:17440 terminated with signal 7 at PC=7f8caca067f4 SP=7fff7c4ffb20. Backtrace: mpi_script_launcher.run:17441 terminated with signal 7 at PC=7fece77297f4 SP=7ffd3b5ff100.

Is there a current recommendation for IB/pbs/torque build flags? — michael _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
