Question
What is the difference between Symmetric Multiple Processing and Massively Parallel Processing?
Solution
Symmetric Multiprocessing (SMP) and Massively Parallel Processing (MPP) are two types of parallel computing architectures. Here are the differences between them:
-
Number of Processors: In SMP, a small number of processors (usually between 2 and 16) are used. On the other hand, MPP uses a large number of processors (potentially thousands) to perform tasks.
-
Memory Access: In SMP, all processors share the same memory and can access it equally. In MPP, each processor has its own dedicated memory.
-
Communication: In SMP, processors communicate through the shared memory. In MPP, processors communicate by passing messages to each other.
-
Fault Tolerance: MPP systems are more fault-tolerant. If one processor fails,
