Explain The Popular Multiprocessor Thread-scheduling Strategies.
threads is maintained. Each processor, when idle, selects a thread from this queue.
Gang Scheduling: A set of related threads is scheduled to run on a set of processors atthe same time, on a 1-to-1 basis. Closely related threads / processes may be scheduledthis way to reduce synchronization blocking, and minimize process switching. Group scheduling predated this strategy.
Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors. For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program.Processors are chosen from the available pool.
