Dealing with big.LITTLE

Post by PaulTV »

For those who bought Alder Lake: there is a new version of Process Lasso that can deal with performance and efficiency cores. I haven't tested it myself (I run an AMD CPU, so don't need that kind of trickery), so to others: share your experience.

Thank you very much for the tip on using Lasso
Out of the box, the Intel 12900K with Windows 10 seemed unwilling to use p cores for folding.
Quickly installed the free version of Lasso and got it folding with all p-cores (no e cores) in 10 minutes.
The Windows 10 result is not surprising because, as you say, the Windows 10 scheduler has not been updated to handle the hybrid processor.
Windows 11 should fix this but Lasso seems very useful anyway.
Thanks again
