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

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

• 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
