Lets add some more data to this... BLACS 1.1p3 Ubuntu Dapper 6.06 dual opteron gcc 4.0 gfortran 4.0 (for both f77 and f90) standard tests with 4 tasks on one node (i.e. 2 tasks per cpu) OpenMPI 1.1.2rc3 The tests comes to a complete standstill at the integer bsbr tests It consumes cpu all the time but nothing happens. Any ideas? configure params: ./configure --prefix=/lap/openmpi/1.1.2rc3/gcc-4.0-dbg --with-tm=/lap/torque --with-pic --enable-mem-debug --enable-debug --enable-picky --enable-cxx-exceptions --with-wrapper-fflags=-ff2c --with-wrapper-fcflags=-ff2c -- Ake Sandgren, HPC2N, Umea University, S-90187 Umea, Sweden Internet: a...@hpc2n.umu.se Phone: +46 90 7866134 Fax: +46 90 7866126 Mobile: +46 70 7716134 WWW: http://www.hpc2n.umu.se
