HELMHOLTZ
  C++ version

  A program which solves the 2D Helmholtz equation.

  This program includes Open MP directives, so that
  it can be run sequentially, or in parallel.

  This program is being run in parallel.

  The number of processors available:
  OMP_GET_NUM_PROCS () = 1

  The number of threads available:
  OMP_GET_NUM_THREADS () = 1

  The region is [-1,1] x [-1,1].
  The number of nodes in the X direction is M = 5
  The number of nodes in the Y direction is N = 5
  Number of variables in linear system M * N  = 25
  The scalar coefficient in the Helmholtz equation is ALPHA = 0.25
  The relaxation value is OMEGA = 1.1
  The error tolerance is TOL = 0.0001
  The maximum number of Jacobi iterations is IT_MAX = 20
