RE: Testing pypastix and no speed up observed on multiple cores

Hello,

Are you on one node or multiple nodes ? If you are using only one node, it is due to the thread binding. they arre bound to the same core. You can change that by using the bindtab array and specify where to bind the threads of each of your processes.

Best
