From "top" command on linux, I only know the CPU utilization percentage. But, I do not how many cores are used in parallel. Any help is really appreciated.
Thanks Are there linux commands that can show all cores utilization ? thanks

thanks for your reply. [...snip...] So, I want to associate each task with a distinct thread and schedule threads as many as possible. Also, try yo make the workload balance among these cores.
How can I do that from the point of programming ?
Hi, I doubt that you can do this kind of things at application (programming) level. Ensuring that all cores are used at best is the responsibility of the operating system in the person of its scheduler. This is because only the O.S. can be aware of everything running on the system beside your program. Thus I believe the answer to your question is not. AFAIK the kernel scheduler in Linux does a god job, even if I never had the occasion of using it on that many cores :)
