class nabu.pipeline.fullfield.chunked_cuda.CudaChunkedPipeline(process_config, chunk_shape, logger=None, extra_options=None, margin=None, use_grouped_mode=False, cuda_options=None)

Bases: ChunkedPipeline

Cuda backend of ChunkedPipeline

Initialize a “Chunked” pipeline.

Parameters:

• processing_config (ProcessConfig) – Process configuration.

• chunk_shape (tuple) – Shape of the chunk of data to process, in the form (n_angles, n_z, n_x). It has to account for possible cropping of the data, eg. [:, start_z:end_z, start_x:end_x] where start_xz and/or end_xz can be other than None.

• margin (tuple, optional) – Margin to use, in the form ((up, down), (left, right)). It is used for example when performing phase retrieval or a convolution-like operation: some extra data is kept to avoid boundaries issues. These boundaries are then discarded: the data volume is eventually cropped as data[U:D, L:R] where ((U, D), (L, R)) = margin If not provided, no margin is applied.

• logger (nabu.app.logger.Logger, optional) – Logger class

• extra_options (dict, optional) – Advanced extra options.

Notes

Using margin results in a lesser number of reconstructed slices. More specifically, if margin = (V, H), then there will be delta_z - 2*V reconstructed slices (if the sub-region is in the middle of the volume) or delta_z - V reconstructed slices (if the sub-region is on top or bottom of the volume).
