Hi! We're having problems with code that uses BLACS and openmpi 1.3.x. When compiled with memory-manager turned on (base only), code using BLACS either start leaking memory or gets into some kind of deadlock. The first code-case can be circumvented by using mpi_leave_pinned_pipeline 0, but the second one could only be solved by compiling openmpi without memory manager.
Building 1.3.1 with ptmalloc2-internal makes the second code break in different ways. Anyone else seen similar problems when using BLACS? -- 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
