Do you know of any business providing remote access to good performance OpenCL GPUs, in a fashion that you could just deploy there your executable without any recompilation nor source code modification? Thanks!!
Some of the Amazon GPU instances have high-end NVIDIA GPUs which support OpenCL. I am not affiliated, just sharing.
Try Remote GPU biz.
You can upload Jar file there and it will be executed. They have Radeon R7 260X OC GPU. Don’t know if this good for You.
Keep in mind, that project is early development stage.
