Shows how to use OpenCL with Go bindings.

Golang OpenCL example

This is a tiny "hello world"-like application that shows how to use the github.com/jgillich/go-opencl OpenCL bindings for Go.

See main.go for some relatively well annotated boilerplate code and kernel.cl for a simplistic kernel that squares each input number by itself.

Example: (OS X)

$ go run main.go
Using: Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz
[0 1 4 9 16 25 36 49 64 81 100 121 144 169 196 225]

OS X

Seems to work out of the box on the two Macs I've tested the program on.

Windows 10

CGO_CFLAGS needs to point at the folder containing the /CL directory that has the opencl.h files. CGO_LDFLAGS needs to point at the folder containing the graphic card provider's .dll files, such as nvopencl.dll.

Linux

Not tested on Linux
