The document discusses a proposed Ruby Summer of Code project to port the NArray numerical array library to use OpenCL, allowing it to take advantage of multicore CPUs and GPUs. The original NArray library only works on single threads. The project was successfully completed, receiving $5,000 in funding. Benchmark results showed the OpenCL version was over twice as fast as the original Ruby version for a complex atanh operation on large arrays. Future work includes full GPU support and reducing data transfer overhead between CPU and GPU memory.
