Update solver with step-40 solution(MPI) #21

Open okmechak opened 4 years ago

okmechak commented 4 years ago

[ ] move to implementation to step-40
[ ] test if all 60 processors are used by program
[ ] measure performance acceleration, and make similar plots as in step-40

okmechak commented 4 years ago

This is quite complicated task.. lets divide it on subtasks even more:

[ ] Study parallelization lectures
- [x] Parallelization: Introduction
- [x] Parallelization on a single, shared memory machine
- [ ] Parallelization on a cluster of distributed memory machines — Part 1: Introduction to MPI
- [ ] Parallelization on a cluster of distributed memory machines — Part 3: Distributed computing in deal.II and step-40
- [ ] Parallelization on a cluster of distributed memory machines — Part 4: Parallel solvers and preconditioners
[ ] Setup system for parallelizatio, describe it in ReadMe.md
[ ] Parallelize assemble_system()
[ ] Implement multigrid preconditioner
....
