Examples

  int shp [1] = {4} ;
  Procs p(1, shp) ;

Creates a one-dimensional process array representing a linear set of 4 processes. The active process group must contain at least 4 processes when the declaration of p is encountered.

  int shp [4] = {2, 2, 2, 2} ;
  Procs h(4, shp) ;

Creates a process array representing a 4-dimensional binary hypercube. The active process group must contain at least 16 processes when the declaration of h is encountered.

  int shp [2] = {2, 3}, ids [6] = {0, 1, 3, 6, 10, 15} ;
  Procs q(2, shp, ids) ;

Creates a process array representing a 2 by 3 grid with a user-defined mapping to members of the active process group. The active process group must contain at least 16 processes when the declaration of q is encountered (because ids includes values up to 15).

  Procs s(0, 0) ;

Creates scalar process grid containing a single process.
