# Overview:
This program solves Dirichlet problem
```math
k(x, y) =
\begin{cases}
-\Delta{u} = f(x,y), & (x,y) \in D \\
u(x, y) = 0, & (x,y) \in \gamma
\end{cases}
```
for a D, that is right trapezoid with next nodes:
$A(0,0)$, $B(3,0)$, $C(2,3)$, $D(0,3)$, - $\gamma$ is its boarder and $f(x, y) = 1 \quad \forall (x,y) \in D$.
The goal is to build accurate and parallel solution, using **OpenMP** and
**MPI** libraries. Moreover launch it on Moscow State University
[Polus](http://hpc.cmc.msu.ru/polus) computing complex.

## Results representation
### Heatmap for solution on grid (M, N) = (160, 180)
# Installation
Clone repository and download python package manager and create venv
```
curl -sSL https://pdm-project.org/install-pdm.py | python3 -
pdm install
```
## For IMP Polus:
To automatically send required code `./Polus/` to your remote Polus space
go to `dodo.py`, change user name in line 15 correspondingly to yours and run
```
doit send
```
After that switch to remote.
Extract `sm24.zip` archive and go to `your_folder_name/Polus/`.
### Launch
You can manfully change grid size in *.cpp files. To change number of processes
or threads open needed *.lsf.
1. `bsub < mpi.lsf` - runs MPI+OpenMP version
2. `bsub < omp.lsf` - runs OpenMP version
## For local testing:
Run CLI command from root directory to create executables:
```
doit build
```
Only `main.cpp`, `mainMPI.cpp` and `mainMPIOpenMP.cpp` are targeted.
### Launch
You can manfully change grid size or number of threads in
1. `./main` - run basic and OpenMP version of program
2. `mpirun -np N ./mpi` - runs MPI version with N processes
3. `mpirun -np N ./ompmpi` - runs MPI+OpenMP version with N processes
All output data would be saved in `build` directory.
To create the heatmaps run from root directory command `doit figures`.
