Foil 11 The Current HPCC Program Execution Model (PEM) illustratrated by MPI/HPF

From The Use of Web Technologies (at NPAC) in HPCC Collaboration and Education Trip to Digital Corporation in New Hampshire -- May 8 97. 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
