How is Co-dfns not what you want? It is by far the best attempt I know of for bringing the full power of APL to accelerators like GPUs[0]. ...however, it is not easy. Full APL has a lot of features (like nested arrays) that are incredibly difficult to map to GPU execution. And in general, APL is not easier to map to GPUs than your bog standard Numpy-style matrix library (in fact it's harder, since Numpy only has regular arrays and simple operations).
