Hi! We have a code that trips on this fairly often. I've seen cases where it works but mostly it gets stuck here.
The actual mpi call is call mpi_file_open(...) I'm currently just wondering if there has been other reports on/anyone have seen deadlock in mpi-io parts of the code or if this most likely caused by our setup. openmpi version is 1.4.2 (fails with 1.3.3 too) Filesystem used is GPFS openmpi built with mpi-threads but without progress-threads -- 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
