OpenCL.lib and multivendor implementation

 

Hello,

 

I'm, writing an application that gonna use OpenCL.

You've currently available a beta OpenCL SDK that requires to link with OpenCL.lib(which indirectly also requires a OpenCL.dll). The question is... imagine I want to use both ATI, NVIDIA and ClearSpeed OpenCL implementations in the same .EXE. How OpenCL.lib would find the proper OpenCL.dll? I bet there will be a conflict...

I think the solution is to modify a bit how you deploy the OpenCL.lib.

1. Rename the OpenCL.dll to ATI_OpenCL_1_0_0.dll ( include company's name + version to avoid DLL hell ).

 

And other question...

How can I enumerate all the OpenCL devices in a machine? Can I use your SDK to enumerate and use, for example, a NVIDIA graphics card? I need a way to do that... like DX10 does with the IDXGIFactory/IDXGIAdapter/IDXGIOutput. A good separation between the Interface and Implementation is vital.

 

thx
