Processor Group Extender

Now Part of Process Lasso

Processor Group Extender

Let group-unaware apps use the whole CPU. On Windows PCs with more than one processor group (more than 64 logical processors), apps that aren’t group aware are confined to a single group. The Processor Group Extender lets them use every group.

See the Processor Group Extender documentation.

How It Works

Threads Assigned Where They’re Needed

This novel algorithm dynamically assigns an app’s active threads to supplemental processor groups as they’re needed, so the app can use the full CPU instead of being constrained to one group.
