Foil 77 The Current HPCC Program Execution Model (PEM) illustratrated by MPI/HPF

From Variety of Foils Used Starting January 97 General -- 1997. by Geoffrey C. Fox *
MPI represents data movement with the abstraction for a structure of machines with just two levels of memory
  • On Processor and Off Processor
This was a reasonable model in the past but even today fails to represent complex memory structure of typical microprocessor node
Note HPF Distribution Model has similar (to MPI) underlying relatively simple Abstraction for PEM
