I don't understand why the conformance tests haven't been officially announced if it's possible to have passed them. They're supposed to have been published in June. Not long... I wonder how AMD's going to treat CPU and GPU. Since OpenCL is meant to run across both, but a single "driver" has to encompass all variations, it seems to me AMD could have a bit of a tussle. CPU -only variant + GPU-only variant + CPU/GPU variant? Hmm. Jawed

Not sure what you mean.
But the nVidia drivers are still beta drivers available to developers only. Not sure when they'll be released to the public. Perhaps when the 190 series goes WHQL?

I think AMD actually has the least of the worries. They have both CPU and GPU drivers in-house.
What will happen if you want to have Intel OpenCL support for your quadcore, but you also have an AMD or nVidia GPU which comes with OpenCL drivers?
What if you have both an AMD and an nVidia GPU in your system? Etc. I hope there's going to be a good way to manage these drivers together.

They could get 2 drivers qualified now and merge them later into one.

If the conformance tests are final then why aren't they published? Not sure what would connect OpenCL and WHQL. Beta status for drivers is "normal" for NVidia, I don't think it's a meaningful qualification. Yes, AMD has a good chance to produce a comprehensive environment (and Intel will have CPU+Larrabee in theory at some point). But it's a lot more work than just producing a GPU-only environment. With both Brook+ (though not all of Stream, i.e. excluding apps coded with IL) and CUDA providing some kind of CPU runtime capability, there's a kind of overlap. e.g. NVidia may in fact produce a driver that fully supports CPU execution - not merely for debugging (which seems to be the usual reason) but for full performance. But if NVidia intends to go beyond debugging I'd guess it's a low priority. Maybe OpenCL 1.1 will sort out the interoperability. Maybe it'll take much longer. Jawed

How do you publish a conformance test? I don't understand what you mean here?

Not sure what you're driving at.
The fact that nVidia's drivers passed OpenCL conformance simply means that they conform to OpenCL 1.0 specifications. It doesn't mean that nVidia considers the entire driver stable enough for release yet (as in, downloadable for end-users as officially supported WHQL drivers, from their main website).
I know end-users can get their hands on *some* of the beta drivers through the website aswell, but afaik not the ones that include OpenCL support. The only way for that is through 'leaks' from registered developers.

The inner circle develops the conformance test for any one else to then use, when they pay the appropriate fee. Those third parties can't use the OpenCL logo until the test is available. Clearly the specification is already public, so third parties can get their product underway. http://www.khronos.org/adopters/ All I'm saying is that the tag "beta" means nothing about the quality of NVidia's drivers. e.g. the driver that has OpenCL support may be unleashed, unchanged, when OpenCL goes fully official. WHQL, per se, has nothing to do with Khronos. Does NVidia normally tie Khronos and Windows drivers together? Jawed

Well, I'm not entirely sure how that goes. Perhaps the conformance tests are available, just not through their website or anything, so we can't see them.
All I know is that on nVidia's site there is a statement that nVidia has sent OpenCL conformance candidate drivers to Khronos:
http://news.developer.nvidia.com/2009/05/nvidia-submits-opencl-10-driver-to-khronos-for-conformance-certification-for-windows-and-linux-.html

While they haven't updated the news yet, various other sites have reported that the drivers came back from Khronos a few days ago, and were fully conformant:
http://www.tcmagazine.com/comments.php?id=27287&catid=3

Why do you say that as if I somehow claimed otherwise?
I'm just saying that these particular OpenCL drivers and OpenCL SDK, although fully conformant now, haven't been released to the general public officially yet. Currently, only registered developers have access.

WHQL may not have anything to do with OpenCL/Khronos per se, but you must realize that OpenCL is just one part of their driver package. nVidia only supports WHQL drivers for regular end-users, and generally they do keep version numbers and releases of Windows and other OSes close together. So in that sense, yes, WHQL has something to do with it. But you already knew that, so I don't see why you're being so argumentative?

Read the link then. I don't see any reason for WHQL to get in the way, since NVidia releases beta drivers for public consumption. So with a green light, it could be quite quick. It's not a big deal. I think OpenCL could be in public hands very rapidly, because WHQL is an un-related log-jam (something like 3 weeks' lead-time, supposedly). Jawed

You'll have to excuse me, at work I don't always have time to read every link, nor do I have access to every site.
But yea, that site answers your question: the tests aren't public, you can only get them when you pay the fee and sign the legal agreement.
After that you still need to send your drivers to Khronos to let them test conformance of the implementation.
Well, nVidia apparently has gone through all that now.

Well no, it's just that I never considered any beta drivers to be 'officially released to the public'. Matter of perspective I guess.
If you really want to get your hands on it, there's a torrent of the drivers and SDK on pirate bay. But you didn't get that from me :)

You guys have no idea how ridiculous you sound right now. :razz:
