Hi Raha
Yes, that is correct.
You have to make sure that max-slots is less or equal to the number of cpus
in the node to avoid oversubscribing it.
Have a look at the other entries in the FAQ, they give information on many
other options you can use.

Dear Jody
Thank you for your reply. Based on hostfile examples you show me, I
understand 'slots' is number of cpus of each node I mentioned in the file,
am I true?

Dear John Hearns
Thank you for your prompt reply. Could you send me a hostfile sample,
please? and a sample command that I must use for my program based on my
last post?

Hi
I think you should use the "--host" or "--hostfile" options:

Hope this helps

Khadije - you need to give a list of compute hosts to mpirun.
And probably have to set up passwordless ssh to each host.
