class BlockDecomposition(nProcs, gridSizes, algo='Hybrid', gRank=None, order='C')[source]¶

Bases: object

Class decomposing a cartesian space domain (1D to 3D) into a given number of processors.

Parameters:

nProcs (int) – Total number of processors for space block decomposition.
gridSizes (list[int]) – Number of grid points in each dimension
algo (str, optional) –
Algorithm used for the block decomposition :
- Hybrid : approach minimizing interface communication, inspired from the [Hybrid CFD solver].
- ChatGPT : quickly generated using [ChatGPT].
The default is “Hybrid”.
gRank (int, optional) – If provided, the global rank that will determine the local block distribution. Default is None.
order (str, optional) – The order used when computing the rank block distribution. Default is C.
