Hi Oneal, Yes, leveraging multicore and the power of GPUs for general computations is great and very powerful but first, securing such kernels is hard, and authoring these would be pretty brutal to most web developers, I think this is what Benjamin was referring to.
With WebCL, you are basically writing C style kernels that you load and run to drive the computations, initiatives like RiverTrail are more restrictive but way more approachable and closer to the web, exposing higher level primitives on top of WebCL (ParallelArray for example) and integrated at the language level, which makes a lot of sense. You can also rely on Web Workers which are now broadly available, also abstracted through libraries like Parallel.js. You won't get shared memory, but improving data passing performance between workers may be a more interesting problem to solve in the short term, with lots of value to most developers.

In recently, Google has pronounced that they will support the multi-process in their browser egin(Blink) which is forked from the webkit. but Google will not supporting the WebCL in Blink. so I just want to know is there a plan supporting the multi-process and WebCL in webkit. I am very curious about the source of interest in OpenCL on browser. While OpenCL is a great technology, I have the feeling it is not ready for the web. What kind of applications do you foresee being powered by OpenCL on the Web? I can imagine some use of CPU based kernels for the web (for image manipulation for example). But I have a hard time seeing how adding full support of OpenCL would not be shooting ourself in the foot at this point. That may change in the future when GPU hardware converges... Cheers, Benjamin
