Foil 28 Broadcast in the Full Matrix Case

From Full Matrices - December 4, 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox, Nancy J. McCracken
Matrix Multiplication makes extensive use of broadcast operations as its communication primitives
We can use this application to discuss three approaches to broadcast
  • Naive
  • Logarithmic
  • Pipe
Which have different performance depending on message sizes and hardware architecture
