Foil 12 Abstract Processors in HPF

From HPFtutorial CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox(Tomasz Haupt)
1 Abstract processors always form a rectilinear grid in 1 or more dimensions
2 They are abstract coarse grain collections of data-points
3 The processor arrangement is defined by the PROCESSORS directive that specifies:
  • name of the processor arrangement
  • the rank (i.e., number of dimensions)
  • the extend in each dimension
4 Examples:
  • !HPF$ PROCESSORS P(N)
  • *HPF$ PROCESSORS BIZARRO(1972:1997,-20:17)
  • CHPF$ SCALARPROC
