Hi Ralph, I tried to build 1.4.3.a1r23542 (08/02/2010) with
./configure --prefix="/g/software/openmpi-1.4.3a1r23542/gcc-4.1.2 2" --enable-cxx-exceptions CFLAGS="-O2" CXXFLAGS="-O2" FFLAGS="-O2" FCFLAGS="-O2"
with the GCC 4.1.2 miket@login002[pts/26]openmpi-1.4.3a1r23542 $ gcc -v Using built-in specs. Target: x86_64-redhat-linuxConfigured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic --host=x86_64-redhat-linux
Thread model: posix gcc version 4.1.2 20080704 (Red Hat 4.1.2-46) but it failed. I am attaching the configure and make logs. regards Michael On 08/23/10 20:53, Ralph Castain wrote:
Nope - none of them will work with 1.4.2. Sorry - bug not discovered until after releaseOn Aug 23, 2010, at 7:45 PM, Michael E.

We have it fixed in the 1.4.x nightly tarballs; can you give it a whirl and see if that fixes your problem? http://www.open-mpi.org/nightly/v1.4/ On Aug 23, 2010, at 8:20 PM, Michael E.

This option is necessary for when our users launch hybrid MPI-OMP code were they can request M nodes and n ppn in a PBS/Torque setup so they can only get the right amount of MPI taks. Unfortunately, as soon as we use the 'npernode N' option mprun crashes. Is this a known issue? I found related problem (of around May, 2010) when people were using the same option but in a SLURM environment. regards Michael <config.log.gz><ompi_info-a.out.gz>_______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users_______________________________________________ users mailing list us...@open-mpi.org <mailto:us...@open-mpi.org> http://www.open-mpi.org/mailman/listinfo.cgi/users_______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
