Explain the popular multiprocessor thread-scheduling
strategies.
Answer / guest
Load Sharing: Processes are not assigned to a particular
processor. A global queue of 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 at the same time, on a 1-to-1
basis. Closely related threads or processes may be
scheduled this 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.
Dynamic scheduling: The number of thread in a program can
be altered during the course of execution.
