This new Jive platform finally works under IE10, but I for one cannot edit my messages, because it keeps importing my very first post of the topic, and I fear editing it, because I think it will edit my first post, not the one I clicked "Edit" upon. Also the advanced editor keeps saying "Page not Found", so I cannot attach files either.

 

To say something on topic: Micah said something at least a year ago, that he started implementing GWS and GDS for OpenCL. It seems that his attempts did not mature to a release candidate, but would it be much work to expose these features via proper vendor extensions? I got no clue how much effort it takes to enhance the compiler with these features are, so I'm just asking. Making barrier(CLK_GLOBAL_WAVE_SYNC) and perhaps giving a __share memory namespace that refers to on-die GDS. Can we expect something like this (which I have been since Micah hinted he is working on these features), or there is simply not enough programming capacity to introduce these features? I understand there are a handful of you guys, and there are heaps of features requested and priority must be made in the order in which they are implemented, but I feel this to be a waste that the HW capability has been inside the chips since the HD5000 series, this could be one of those kick@ss features that the competition is not capable of, and it is simply left unimplemented on the SW side and topics like this have to be made in order to get working,
