This example just does some basic calculations on data structures and reports the time difference between the CPU and GPU. Getting about a 20x speedup on a Macbook Pro M3 Max.
There is a //go:generate comment directive in main.go that calls gosl on the relevant files, so you can do go generate followed by go build to run it. There is also a Makefile with the same gosl command, so make can be used instead of go generate.
The generated files go into the shaders/ subdirectory.
