Currently I am working on a semester long project to learn various
numerical methods like Gauss Elimination, Gauss Jacobi, Gauss Seidel
methods etc. to learn how to do the computations using MPI(Message Passing
Interface). Later I will be learning how to solve boundary value problem
using finite difference method using the same tool - MPI. The idea is to
develop a library which could make use of parallel programming to achieve
the objective of solving boundary value problems. I would love to hear
suggestions regarding the same.
