i see intel opencl sdk,a plugin for vs 2008 , is free?
i can use it with the microsoft cpp compiler?
thanks.

ps. i use win vista 64 bit and i know visual studio.

It depends on what OpenCL platform you are using.

For AMD/ATI:
http://developer.amd.com/tools/gdebugge … fault.aspx

For NVIDIA:
http://developer.nvidia.com/nvidia-parallel-nsight

Both of those integrate into Visual Studio. The NVIDIA one likely has more features than the AMD one.

Not sure about Intel (I don’t use Intel for OpenCL).
