Bohrium

"Bohrium provides a runtime environment for efficiently executing vectorized applications using your favourite programming language Python/NumPy, C#, F# on Linux, Windows and MacOS.

Forget handcrafting CUDA/OpenCL, forget threading, mutexes, and locks, use Bohrium!

The features include:

• Lazy Evaluation, Bohrium will lazy evaluate all Python/NumPy operations until it encounters a “Python Read” such a printing an array or having a if-statement testing the value of an array.
• Views Bohrium supports NumPy views fully thus operating on array slices does not involve data copying.
• Loop Fusion, Bohrium uses a fusion algorithm that fuses (or merges) array operations into the same computation kernel that are then JIT-compiled and executed. However, Bohrium can only fuse operations that have some common sized dimension and no horizontal data conflicts.
• Lazy CPU/GPU Communiction, Bohrium only move data between the host and the GPU when the data is accessed directly by Python or a Python C-extension.

Bohrium implements a new python module bohrium that introduces a new array class bohrium.ndarray which inherent from numpy.ndarray. The two array classes a fully compatible thus one only has to replace numpy.ndarray with bohrium.ndarray in order to utilize the Bohrium runtime system.
