What kernel does my process work in?

Question

I am currently in the parallel programming class, and our first programming exercise was to create four threads that displayed a hi-world, like a message. I would like to know in which cores the threads work. I tried using the TOP command on Unix to display all processes, and I see 5 different threads, but I don’t know how to find out which kernels start each thread.

Answer 1

The j field above,, Pshows you which kernel the thread / process was working from.
