MGCG Method

MGCG method is a conjugate gradient with multigrid preconditioner. This library solves a linear system of equations whose coefficient matrix has five or seven diagonals that typically arises from discretization of two-dimensional or three-dimensional problem respectively.

FORTRAN [ SERIAL / OpenMP ]

2002/5/2 [2D] Arguments for MGCG are simplified.
[2D] More optimization for OpenMP.
[2D] MFLOPS is now reported.

2000/6/22 MGCG for three-dimensional problem is released!

1999/11/12 [MGCG_S] Added ITER and EPS as INPUT arguments.
You need to change arguments for MGCG_S.
[RB_GS] Fixed a bug when N is less than 4.
[Restriction] Parallelized by OpenMP.
Added a new 'T-shape' problem.

1999/9/9 OpenMP support

1999/4/15 Initial version
