kferjaoui	ea32b530e8	python: bind PixelHistogramCUDA ... PixelHistogramCUDA_<input>_<storage> for uint16, float32 and float64 frames and the six storage types of PixelHistogram, behind an aare.PixelHistogramCUDA() factory. Frames are never converted: a wrong dtype raises TypeError, so a registered buffer is always the one copied. The GIL is released during GPU work. - C++: fill_histogram() and submit_batch() take const views, so read-only arrays (np.memmap mode="r") work; register_output_buffer() pins the destination of values(out). - Python: register_input_buffer()/register_output_buffer() keep their array alive; values(out=...) writes into a given array. With a pinned out, reading back a 640 MB histogram takes 28 ms instead of 230 ms. - Tests in test_PixelHistogramCUDA.py; PixelHistogramCUDA.ipynb compares CPU and GPU on 100k Moench frames (identical, ~13x faster on the GPU).	2026-10-21 17:35:42 +02:00
kferjaoui	a42d71cf42	Graph-based CUDA ClusterFinder (ClusterFinderCUDAGraph) ... - CUDA Graph variant of ClusterFinderCUDA: one pre-recorded graph per stream (memset + H2D + kernel + D2H), with per-frame src/dst pointers swapped via cudaGraphExecMemcpyNodeSetParams to cut per-frame launch overhead. - Exposed through the _aare_cuda bindings and a ClusterFinderCUDAGraph factory.	2026-08-03 11:53:51 +02:00

kferjaoui	e894bdac9b	Add Python bindings for CUDA cluster finder ... - Add bind_ClusterFinderCUDA.hpp with pybind11 bindings for ClusterFinderCUDA - Build CUDA bindings as separate _aare_cuda.so to avoid segfaults from mixing nvcc and gcc compiled code in the same shared object - Re-export CUDA classes onto _aare in __init__.py so user code uses `from aare import ClusterFinderCUDA` regardless of which .so hosts the class - Factory in ClusterFinder.py selects backend; RuntimeError if GPU requested on CPU-only build - Update python/CMakeLists.txt: _aare_cuda module gated behind AARE_CUDA and AARE_PYTHON_BINDINGS - Add validation notebook: ~20x speedup vs sequential ClusterFinder	2026-04-23 11:43:40 +02:00
