Check which thread is running on which CPU in linux

I'm interested in finding which thread is running on which core/CPU. My Tomcat6 is using a single CPU core 100% and all other CPUs (my server has 16 other cores idle) are not being utilized... so I'm trying to figure out what went wrong.

Funny that people downvotes but don't tell why. I searched for a while and found that following command gives which thread running on which CPU:

ps -p <PID> -L -o pid,tid,psr

Where < PID > is the pid of the process we are interested in.
