Q:

Explain the popular multiprocessor thread-scheduling strategies.

Answer

  1. 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. Note that load balancing refers to a scheme where work is allocated to processors on a more permanent basis.

  2. 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 / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching. Group scheduling predated this strategy.

  3. 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.

  4. Dynamic scheduling: The number of thread in a program can be altered during the course of execution.

A) be traveling at a speed that is faster than perceived B) be traveling at a speed that is slower than perceived
C) Both A & B D) None of the above
 
Answer & Explanation Answer: A) be traveling at a speed that is faster than perceived

Explanation:

Velocitation is a phenomenon caused by driving for long periods at high speeds. A driver may experience velocitation when coming off of the highway; the change in speed makes him or her think that the car is going much slower than it actually is.

 

Velocitation is the tendency to be traveling at a speed that is faster than perceived.
