Foil 6 Performance of HPF

From DoD HPF Training -- 1. Introduction to HPF DoD Training and Others -- 1995-98. by Chuck Koelbel -- Rice University
Performance is highly dependent on the compiler and on the nature of the code
  • Best performance is for data-parallel computations
  • Tie ³natural² parallelism in the problem to distributed array dimensions
Commercial compilers are now competitive with MPI for regular problems
  • Subscripts like A(L+1,K-1)
Research continues on irregular problems and task parallelism
  • Subscripts like A(INDX(I1,2))
  • Tree searches with branch-and-bound cutoffs
