Foil 3 Two Major Parallel Programming Paradigms

From Applications and their Relation to Software CRPC/MCNC Workshop -- April 10-13 1995. by Geoffrey C. Fox
1 Data Parallel and Message Parallel
2
These are Message Parallel and Data Parallel Resources
  • Suggest Message Parallel Fortran as description of Fortran plus Message passing (Per Brinch Hansen) to be consistent with HPF or CMFortran as Data Parallel Fortran
3 There are trade-offs in Ease of Programming (not same for each user!), Portability, Maturity of Software, Generality of Problem class
4 Message Parallel is most mature, somewhat less portable in principle but not necessarily in practice, tackles all problems and some consider painful to program
  • Most succesful parallel applications have been Message Parallel
  • Fortran-M and MPI will describe this approach
