I am happy that you illustrated how many algorithms could be parallelized by the G4 instruction set. I had thought that Apple was only selling the cocoa frameworks and would never discuss parallel algorithms constructed in near pseudocode, but Apple is also in the business of selling hardware and it's instruction sets. I have hope that I shall learn how to organize myself into making my own frameworks of objects cotaining algorithms to save my "knowledge work" in science, not merely interface, be interface ever so important for science.

Seemed to me the major speedup is in Apple's matrix multiplication algorithm exploiting the G4 arrray processor not in the multiprocessor cluster.
Is that correct?
So far got to page 14 of the Jy 2000 report "Evaluation of Powermac G4 Systems for Fortran-..."
