Question

I was reading through galvin chapters on process and thread Looking at processes , multiple processes are scheduled by the cpu scheduler or short term scheduler , after this comes the concept that a thread is a path of execution and a process can contain multiple threads . Now i thought of a scenario , Suppose the cpu scheduler schedules a process for execution using round robin algo , now suppose the scheduled process has 50 threads , now in this scenario how are the threads withing the same process scheduled and how does the context switch b/w threads , process happen Can plz sm one explain me the entire scenario in detals , i will be very thankfullll

Answer 1

Process is a program in execution and its the job of the programmer to decide the number of threads in that process and how they would be scheduled.. it depends on which sequence he would like the program to run.. so as soon as the process is in running state it would run the thread that was scheduled to run by the programmer.. Even in case of threads running concurrently its the programmer who decides which threads can run concurrently and which cannot.. i hope this clears your doubt.
