In a nutshell, Otoy reverse-engineered Nvidia’s general purpose graphics processing unit (GPGPU) software, known as CUDA, to run on non-Nvidia hardware. That means that programs written in the CUDA language are no longer exclusive to Nvidia graphics chips. Now they can run on GPUs from Advanced Micro Devices, ARM, and Intel. That means a CUDA program written for the PC could run on a PlayStation 4 or an Apple iPad.

Otoy has ported the CUDA language to run on AMD, Intel, and ARM GPUs for the first time ever. That means any application written in CUDA can run, without modification, on all major chipsets and platforms. While there is an independent GPGPU standard dubbed OpenCL, it isn’t necessarily as good as CUDA, Otoy believes.
