Foil 3 Comments on Fundamental Issues

From Remarks on Fox's White Paper and Working Group Report PetaSoft Foolow-On Meeting San Diego -- January 28,29 1997. by Geoffrey C. Fox
1 Seem to be easiest for PIM architectures for classic geometrically data parallel problems -- even if adaptive and irregular (these are "engineering" issues)
2 Must extend MPI HPF .. HPJava to support several layers of memory hierarchy
3 Need to study data movement in key algorithms and how they can be supported in all prototypical architectures
4 Can possibly use "load balancing ideas" (developed for decomposition onto CPU's today) to address fine grain memory hierarchy decomposition in PetaFlop architectures
5 Need layered software model with capability to "escape" to lower levels
