Impossible to adresse a CPU cores uper than 32 with timed loop

Hi !

I come back after my previous post on this subject who has been closed (by my self) too quickly apparently.

I am working on a 4 sockets computer with 4 intel xeon CPU 18 cores, 36 threads each. So 144 threads in total.

I tri to get the most out of this machine but i can't run any programme on more than 32 threads.

I learned about CPU group that Windows creat but in my case it creat group of 36 cores, so i should be eable to acces at least this 36 cores.

In this small exemple I can adress cores from 0 to 31 but if i select core 32 or more it's the core 0 who run.

 

 

Does any one, who have a computer with more than 32 cores, can try to run the same code to see if the result is the same.

Any one have an idea ?

You should provide a link to that other thread.

And technically, you can't "Close" a post.  You may have marked a post in the thread as the solution, but it doesn't close it.  You or anyone else can still post messages in there as necessary.
