Welcome
This is my dev wiki for the DSI OpenCL… Right know i am more focused on the OpenCL library and the openCL language that is used to create the kernel.
I will make sure that i explain how it works and what is happining so that if anyone wants to compile it on their computer they will be confident that it will work correctly
== THIS CODE DOES NOT RUN BUT DOES COMPILE USE AT OWN RISK ==
