c program for cpu threading

need a help to develop a CPU scheduling algorithm that will complete the execution of a group of multi-threaded processes in an OS that understands threads (kernel threads). Since a real implementation of your scheduling algorithm is not feasible, you will implement a simulation of your CPU scheduling algorithm. Each process will have 1-50 threads; each of the threads has its own CPU and I/O requirements. Your simulation program will be invoked as: $ ./simcpu [-d] [-v] [-r quantum] < input_file where • -d stands for detailed information • -v stands for verbose mode • –r indicates Round Robin scheduling with the given quantum (an integer)
