Table 1.
Computational time with both explicit and implicit solvers on CPU and GPU.
| Scheme | Number of time steps | Computational time OpenMP (s) | Computational time CUDA (s) |
|---|---|---|---|
| Explicit | 73823 | 6991 | 839 |
| Implicit (non-parallel update) | 1 | 60 | 93 |
| Implicit (parallel update) | 1 | 44 | 77 |
Notes. With the implicit solver, the matrix is updated in a parallel or a non-parallel way. The implicit solver uses the AMG preconditioner.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
