SMP Sample

Description

This program spawns off 3 threads in a suspended state. It will then, using a round robin technique, assign a processor to run each thread. Each thread will kick off and start stating a unique statement for each iteration and continue until the first thread signals completion. Upon completion, the main thread will shut down all the threads and commence cleanup and shut down the program.
