Description: mpi fortran wave equation solver code
!cc MAIN is the main program for WAVE_MPI.

!c
!c WAVE_MPI solves the wave equation in parallel using MPI.
!c
!c Discretize the equation for u(x,t):
!c d^2 u/dt^2 - c^2 * d^2 u/dx^2 = 0 for 0 < x < 1, 0 < t
!c with boundary conditions:
!c u(0,t) = u0(t) = sin ( 2 * pi * ( 0 - c * t ) )
!c u(1,t) = u1(t) = sin ( 2 * pi * ( 1 - c * t ) )
!c and initial conditions:
!c u(x,0) = g(x,t=0) = sin ( 2 * pi * ( x - c * t ) )
!c dudt(x,0) = h(x,t=0) = - 2 * pi * c * cos ( 2 * pi * ( x - c * t ) )

!c alpha = c * dt / dx.
!c
!c U(x,t+dt) = 2 U(x,t) - U(x,t-dt)
!c + alpha^2 ( U(x-dx,t) - 2 U(x,t) + U(x+dx,t) ).
