CPU affinity not working.

[J. B.]

After 3 years after when I post my problem Affinity still is not working: Dual Xeon E5-2697 v4  (36/72). Is something change in LassoPro that I can setup to solve problem?

Process Lasso now supports multiple processor groups (except for the graphs), and a novel technology (Group Extender) that allows group unaware apps to use the entire CPU instead of only a single processor group.

However, there are some fundamental limitations in Windows around processor groups.

A system like you describe, with more than 64 logical cores, would have two processor groups. In your case, 36 cores each.

If you play with the group extender, I'd love to hear your experiences. Email me at support@bitsum.com

If that doesn't suffice, please clarify your issue.
