Foil 53 Fundamental Parallelism Assumption in HPF

From New CPS615HPF and Fortran90 Discussion Sept 17 96 Basic Simulation Track for Computational Science CPS615 -- Fall Semester 96. by Geoffrey C. Fox, Tom Haupt
An operation on two or more data object is likely to be carried out much faster if they all reside in the same processor
  • i.e. minimize communication
it may be possible to carry out many such operations concurrently if they can be performed on different processors
  • data parallelism
