It is time consuming and very skillful task for researchers or developers on computational mechanics to modify a program for a single processor to the one for parallel computation. This is a serious bottleneck for parallel computation, even though general purpose parallel computational library such as MPI is applied in his modification. We developed a parallel matrix solver platform based on domain de composition scheme for various numerical schemes such as finite element method, finite difference method, and finite volume method to accelerate a smooth shift to parallel computational world. What a user should do is just to call the platform at the stage of stiffness matrix calculation. GMRES, Bi-CGSTAB and banded matrix solvers are used as a basic matrix solver with some options of pre-conditioner. The latest version 1.0 is introduced in this paper.
