    In an attempt to rekindle embers long thought extinguished, ATI releases some shockingly useful tools.

    Presumably, this works on any/all OpenCL-compatible hardware, and not just AMD stuff? It seems all-inclusive from the general flavor of the news blurb, but it doesn't explicitly state outright either way so I thought I'd ask. :)

    Theoretically, it should, with the restriction that OCL leaves quite a bit of "undefined behaviour" up to IHV interpretation, so some things may not be portable. In Windows space, Bolt is intended to run atop C++ AMP (as well) with a somewhat less arcane syntax (last time I saw Bolt code, it relied on some macros on the OCL side for hiding a few of the intricacies, f.e. using custom predicates or whatnot), so I'd expect it to homogeneously run across the span of DX11+ capable HW. In Linux, it's likely to work well with AMD and Intel, but NVIDIA's less fond of OCL, and they're also yet to ship CL1.2 support, which Bolt might rely on.

    Disregard the parts in red, it appears that ATI decided to use its Static C++ Kernel Language extensions, which, unsurprisingly, is exposed only by ATI currently. It remains to be seen whether that ever makes it into the standard and how it will play with ATI's current proposal, but what it boils down to is that Bolt OCL will only work with ATI's stack for the time being. Sorry for the mixup.

    On a related note, we're (incredibly slowly) working towards having an article that looks at the GPU compute landscape as it is today, now that APIs have grown a bit and tools are out that make it worthwhile to take a peek.

    I believe, most of you are registered on newsletter from AMD developers central, but Bolt 1.0 have just been released, along of - CodeXL 1.2 and AMD OpenCL APP SDK 2.8.1. ..

    Also some interessant other news on some software update for OpenCL with " Marc ":
    who come join all the other software allready accelerated ( from maya, Adobe products ( premiere, photoshops, elementy
    etc ). ( was not rememeber so much software include openCL now )
