Howdy,
I wrote OpenCLV (OpenCL for Labview) about a year ago and have decided to make it an Opensource project availible on GitHub. It contains all my C code to compile DLLs, all the Labview code, some pre-compiled x64 DLL code and a pre-built .vip project if you just want to download and install it.

My email is in the GPL license header in the C code if you find any bugs or have any comments.
