I'm not insisting on this concrete proposal, my point is just that it would be more safe and natural to enhance ECMAScript (enable parallel calculations there) rather than make developers to introduce OpenCL snippets to their web apps.

Good alternative could be enabling parallel calculations inside ECMAScript itself. For instance providing ParallelArray interface for map-reduce calculations, there is actually a proposal already at http://wiki.ecmascript.org/doku.php?id=strawman:data_parallelism .

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… There has also been interest in the WebAudio WG about using OpenCL/WebCL for custom audio processing. There are significant performance issues involved with doing custom audio processing in JavaScript, even in a Worker thread, but WebCL may offer performance and memory characteristics which would couple well with the requirements of realtime audio threads. -Jer --------------------------------------------------------------------- Intel Finland Oy Registered Address: PL 281, 00181 Helsinki Business Identity Code: 0357606 - 4 Domiciled in Helsinki This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
