Foil 7 Why use Processor Groups?

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
1 We find a good example when we consider typical Matrix Algorithm
2 (matrix multiplication)
3 A i,j = Sk B i,k C k,j
4 summed over k'th column of B and k'th row of C
5 Consider a square decomposition of 16 by 16 matrices B and C as for Laplace's equation. (Good Choice)
6 Each operation involvea a subset(group) of 4 processors
