PRAM Model for Parallel Computation

PRAM Model for Parallel Computation

PRAM Model for Parallel Computation. Chapter 1A: Part 2 of Chapter 1. The RAM Model of Computation Revisited. The Random Access Model (or RAM) model for sequential computation was discussed earlier. Assume that the memory has M memory locations, where M is a large (finite) number

PRAM Algorithms

PRAM Algorithms

PRAM Algorithms. Parallel Random Access Machine (PRAM). PRAM instructions execute in 3- phase cycles Read (if any) from a shared memory cell Local computation (if any) Write (if any) to a shared memory cell Processors execute these 3-phase PRAM instructions synchronously.
