This example was directly taken from fortran-lang. It proposes to benchmark different implementations of a solver for the 2D Poisson equation. The solver uses a simple Jacobi iteration methods. For details, see, "Computational Physics" by Mark Newman, Chap 9.
The benchmark consists in testing two different implementations in Fortran for a given tolerance (10^-6) and a given number of grid point (30).
The results are as follows:
| Method Name | Mean | Standard Deviation |
|---|---|---|
| poisson_naive(1.0d-6,30) | 161.750 ms | +/- 11.252 ms |
| poisson_optimized(1.0d-6,30) | 93.025 ms | +/- 5.981 ms |
