With both SDK installed (but only ATI GPU) I see both platforms too. Then I can chose ATI's one and use ATI's GPU, not problems with that (until app sees local OpenCL.DLL, not NV's one installed into system32 directory). Problems with both ATI and NV GPUs installed looks much more like Cat 10.4 bug not directly connected with OpenCL. Catalyst doesn't see ATI GPU while both NV and ATI GPUs installed. That's why I hope it will be resolved soon (with new catalyst release).

Would the app even start to run? Would it run and then fail to find the suitable GPU? When having multiple cards from NVIDIA and ATI, The ideal situation would be having different platforms. Look at this output from a program run on my computer to see how both ATI's OpenCL (platform 0 for the CPU) and NVIDIA's OpenCL (platform 1 for the GPU) are present: AQUAPT started on Fri May 14 09:57:03 2010 Executable file: c:\Kamran\AQUAPT_V4\AQUAPT_OCL_NVIDIA.exe Found 2 OCL Platforms Platform number: 0: Platform profile: FULL_PROFILE Platform version: OpenCL 1.0 ATI-Stream-v2.0.1 Platform name: ATI Stream Platform vendor: Advanced Micro Devices, Inc.

Now if only this worked for multiple GPUs from different vendors! -Kamran -----Original Message----- From: Raistmer [mailto:[email protected]] Sent: Monday, May 17, 2010 12:57 PM To: Kamran Karimi; David Anderson Cc: [email protected] Subject: Re: [boinc_dev] BOINC now supports OpenCL > I'd imagine a user would install either an >NVIDIA or an ATI driver.

I would not await that number of such users will decrease, quite reverse can be true. For now we at Lunatics team were not able to make ATI AP work on NV + ATI GPUs host. NV GPU had to be removed to ATI GPU start to work OK. But ultimately app should be able to function when both GPUs installed. I keep in mind such situation while providing OpenCL.DLL along with app binaries itself. But how to manage this when same project would be able to use OpenCL on both types of GPUs?... 2 OpenCL.DLL in single project directory - not good solution :) -----Original Message----- From: Raistmer [mailto:[email protected]] Sent: Saturday, May 15, 2010 1:11 AM To: Kamran Karimi; David Anderson Cc: [email protected] Subject: Re: [boinc_dev] BOINC now supports OpenCL Do you have OpenCL for ATI GPUs already? The problem of shipping OpenCL.dll with app strats when both SDKs (and both DLLs ) present on user PC. NV OpenCL.dll resides in system32 (that is, "system" file, no need to distribute indeed) but it can't handle ATI's OpenCL library calls. ----- Original Message ----- From: "Kamran Karimi" <[email protected]> To: "David Anderson" <[email protected]> Cc: <[email protected]> Sent: Saturday, May 15, 2010 2:19 AM Subject: Re: [boinc_dev] BOINC now supports OpenCL > BTW there was no need to supply any OpenCL.dll files with the app. We > sent the OpenCL kernel source to volunteer computers and compiled it at > execution time with no problem. > > In short, things worked smoothly. > > -Kamran > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Kamran Karimi > Sent: Friday, May 14, 2010 3:15 PM > To: David Anderson > Cc: [email protected] > Subject: [boinc_dev] BOINC now supports OpenCL > > I am happy to report that we successfully tried an NVIDIA OpenCL test > version of our AQUA app on volunteer computers. > > There is no way to know for sure whether people who ran the work units > on their computers had OpenCL SDKs or not, but we didn't see any > failures, which means that every user with the appropriate NVIDIA driver > version (197.13+) who downloaded the OpenCL app ran it successfully to > completion. > > We have an ATI OpenCL test version of the app too.
