Linux

History:

1. ZLUDA starts as a project to make CUDA work on Intel GPUs, with funding from Intel.
2. Intel pulls funding, author manages to get funding from AMD instead.
3. Development of a new version targetting AMD GPUs happens under closed doors with the informal agreement that the source code will be publicly released if AMD pulls funding.
4. After a couple of years, AMD pulls funding and the source code for the new version is released.
5. Development continues in the open for a few months, albeit at a slowed pace.
6. AMD goes back on their word, claims previous agreement wasn't legally binding and asks that ZLUDA source code be taken down.
7. Author reverts codebase to its pre-AMD state, looks for new source of funding.
8. ZLUDA's Third Life
9. Anything regarding NVIDIA involvement is pure speculation and should be treated as such.
