Foil 30 Current HPF can also do the Embarassingly Parallel

From Programming Paradigms B CRPC/MCNC Workshop -- April 10-13 1995. by Geoffrey C. Fox
1 In Embarrassingly Parallel Problems, the basic entities can be very complicated but they can be calculated independently.
  • Use DO INDEPENDENT command in HPF
2 Search databases for given text (can be SIMD)
3 Analyze separately 10**7 events recorded from Synchrotron (SSC) collisions. ( definitely MIMD "farm" )
4 Calculate matrix elements for (chemistry) Hamiltonian (may need MIMD)
5 Programs such as MOPAC, GAUSSIAN
  • "Calculate matrix elements"
  • "Multiply/Solve/Find eigenvalues of matrix"
  • Similar issues in Computational Electromagnetics
6 Quantum Monte Carlo
  • Independent "walkers"
  • Parallel Histogram (database) storage (reduction again)
