Rohit, Can you try the latest mpich version (3.0.1)? There are some fixes in there that might be related to this. -- Pavan On 11/06/2012 04:34 PM US Central Time, Jain, Rohit wrote:
Thanks John. That does give me list of available binding option.
It seems all binding options don�t work fine.
All l1/l2/l3cache errors out:

Rohit,
Did you try
$ mpirun -bind-to -help
This dumps all of the options for -bind-to.

Hi Pavan,
Where do I find exact names of new binding options arguments?
Like 'sockets' doesn't work, but 'socket' do. This page is not updated with correct options: http://wiki.mcs.anl.gov/mpich2/index.php/Using_the_Hydra_Process_Manager#Pro...

Do you mean '-binding' option is also being deprecated? Is it replaced with '-bind-to'?
It's being replaced with the -bind-to option. We might support -binding as an alias to -bind-to for quite some time, but we'd suggest users move to the new richer -bind-to interface.
