Intel 12th Gen and Matlab
Show older comments
As Intel move to a big-little, hydrid core design CPU. I wonder how Matlab flair with it.
Some more specfic question,
Does Matlab work well with Windows 11 + Intel scheduler in assigning multiple threaded task?
Can I specfic Matlab to use the power-core first before the E-Core?
If I am building a new desktop with a Intel 12th gen CPU, is it better to stay with Win10 to maximize Matlab's performace at the moment?

I have seen hints that MATLAB is not completely stable on WIndows 11 yet. I gather that this is at least partly the fault of Windows 11; MATLAB and Windows 11 are both likely to improve. I just would not recommend relying on the combination yet.
I do not happen to have any information about task scheduling on MATLAB on Windows.
On MacOS, the usual procedure would be just to ask for threads, and let the operating system schedule them; the operating system would migrate them to the power core as it detected harder work to be done (MacOS already does this for Apple's M1 systems)
On Linux, migration to faster cores should generally happen automatically, but I do not know the extent to which it is implemented. A paper I was reading a few days ago did talk about the benefits of pinning processes to cores on Linux -- but the paper was written long enough ago that automatic migration might plausibly be more common now.
