i can use it with the microsoft cpp compiler?

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

It depends on what OpenCL platform you are using.

For AMD/ATI: … fault.aspx


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).
