Nvidia CUDA 的 EULA 禁止跑在模擬層上面

Hacker News 上看到「Nvidia bans using translation layers for CUDA software to run on other chips (tomshardware.com)」這個討論串,原報導「Nvidia bans using translation layers for CUDA software — previously the prohibition was only listed in the online EULA, now included in installed files」。

文章最上面更新的這段把重點講完了,在 11.6 之後的版本就有加入這段文字了:

[Edit 3/4/24 11:30am PT: Clarified article to reflect that this clause is available on the online listing of Nvidia's EULA, but has not been in the EULA text file included in the downloaded software. The warning text was added to 11.6 and newer versions of the installed CUDA documentation.]

主要是這條:

You may not reverse engineer, decompile or disassemble any portion of the output generated using SDK elements for the purpose of translating such output artifacts to target a non-NVIDIA platform.

從「CUDA Toolkit Archive」這邊可以看到 11.6.0 是 2022 年一月的事情:

CUDA Toolkit 11.6.0 (January 2022), Versioned Online Documentation

看起來跟 ZLUDA 有關 (參考「IntelAMD GPU 直接跑 CUDA 程式的 ZLUDA」)。

時間軸看起來有對起來,2021 年的時候被 Intel 找去聊,2022 年的時候改跟 AMD 簽約,然後 AMD 後來也放掉:

In 2021 I was contacted by Intel about the development of ZLUDA. I was an Intel employee at the time. While we were building a case for ZLUDA internally, I was asked for a far-reaching discretion: not to advertise the fact that Intel was evaluating ZLUDA and definitely not to make any commits to the public ZLUDA repo. After some deliberation, Intel decided that there is no business case for running CUDA applications on Intel GPUs.

Shortly thereafter I got in contact with AMD and in early 2022 I have left Intel and signed a ZLUDA development contract with AMD. Once again I was asked for a far-reaching discretion: not to advertise the fact that AMD is evaluating ZLUDA and definitely not to make any commits to the public ZLUDA repo. After two years of development and some deliberation, AMD decided that there is no business case for running CUDA applications on AMD GPUs.
