PyCUDA lets you access Nvidia's CUDA parallel computation API from Python.

Key Features:

• Maps all of CUDA into Python.
• Enables run-time code generation (RTCG) for flexible, fast, automatically tuned codes.
• Added robustness: automatic management of object lifetimes, automatic error checking
• Added convenience: comes with ready-made on-GPU linear algebra, reduction, scan. Add-on packages for FFT and LAPACK available.
• Fast. Near-zero wrapping overhead.
•  Complete, helpful documentation.

Performance Benefits:

• See the PyCUDA FAQ for a discussion about libraries, debug support, profiling, and multiple GPUs

Availability:

• Freely downloadable from this location, open source, MIT licensed
