I tried this and it still crashes with openmpi-1.4. Is it supposed to work with openmpi-1.4 or do I need to compile openmpi-1.4.1 ?
Terribly sorry, I should checked my own notes thoroughly before giving others advice. One needs to give the dynamic rules file location on the command line:
mpirun -mca coll_tuned_use_dynamic_rules 1 -mca coll_tuned_dynamic_rules_filename /homeXXXX/.openmpi/dynamic_rules_file
That works for me with openmpi 1.4. I have not tried 1.4.1 yet. Daniel
