如何在 windows 中使用 CUDA 的协作组功能 [英] How can using cooperative groups feature of CUDA in windows

问题描述

我的 GPU 是 GeForce MX150，pascal 架构，CC.6.1、CUDA 9.1、Windows 10.虽然我的 GPU 是 pascal 但协作组不起作用.我想用它进行块间同步.
我发现我的 tcc 模式未激活.
我还发现它在 Windows 中的 wddm 中不活跃.
如何使用协作组?
如何在 Windows 中激活 tcc 模式?
感谢您的回复.

My GPU is GeForce MX150, pascal architecture, CC. 6.1, CUDA 9.1, windows 10. Although my GPU is pascal but cooperative groups doesn't work. I want to use it for inter-block synchronization.
I found my tcc mode doesn't active.
I also found that doesn't active in wddm in windows.
How can using cooperative groups?
How can activate tcc mode in windows?
Thanks for your reply.

推荐答案

在那个GPU上不能激活TCC(不支持)，在windows WDDM模式下无法使用协同启动.

You can't activate TCC on that GPU (it is not supported), and there is no way to use a cooperative launch under windows WDDM mode.

您要么需要切换到 linux，要么需要另一个(pascal、volta、turing)GPU，它可以在 Windows 上置于 TCC 模式下.

You'll either need to switch to linux or get another (pascal, volta, turing) GPU that can be placed in TCC mode on windows.

另请参阅您的其他问题，了解如何以编程方式查询支持这个功能.
