Hi all, I am now doing research on a 4x4 machine. I want to know what cores are running in each thread . Beside , I want to find out whether the 4 cores running in the same thread are on the same die , is there anyone who knows how to do this ? Thank you very much!


Oh, and on AMD processors you can use RDTSCP (Read Time-Stamp Counter and Processor ID) instruction.
