You will have to have bindings specified for all your ranks in the case you describe. I would like to, but whenever the list of comma-separated CPU ids contains more values than there are CPUs in the system I get an assertion failure.

For example: My test system has 4 CPUs. If I try to run 'mpiexec -np 9 -bind-to user:0,1,2,0,1,2,0,1,2 /some_path/some_binary' Hydra will crash and show the error I pasted in my original message. Regards, Jan
