But, I have these,

orte-clean orted orte-iof orte-ps orterun

Can they do the same thing ?

If I use them, will they use a lot of memory on each worker node and print out a lot of things on some log files ?

Any help is really appreciated.

Thanks

Jack

What version are you using? If you are using 1.5.x, there is an "orte-top" command that will do what you ask. It queries the daemons to get the info.

Hi , All:

I need to monitor the memory usage of each parallel process on a linux Open MPI cluster.

But, top, ps command cannot help here because they only show the head node information.

I need to follow the behavior of each process on each cluster node.

I cannot use ssh to access each node.

The program takes 8 hours to finish.

Any help is really appreciated.
