I don't know what happens when a user has both an NVIDIA and an ATI GPU. To answer your question, I don't have an ATI card, but I have installed ATI's SDK. As a result, now I have two OpenCL "platforms" available to me. The ATI platform supports the CPU, while the NVIDIA platform supports my CUDA card.
As you said, an app compiled with NVIDIA's OpenCL.lib file can't run with an ATI OpenCL.dll. I'd imagine a user would install either an NVIDIA or an ATI driver. Either way the project doesn't have to include a suitable OpenCL.dll file with the application. -Kamran -----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.
