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. 尽管我的GPU是Pascal，但是合作小组无法正常工作.我想将其用于块间同步.
我发现我的tcc模式没有激活.
我还发现在Windows的wddm中它不起作用.
如何使用合作组?
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

您无法在该GPU上激活TCC(不支持)，并且无法在Windows WDDM模式下使用协作启动.

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，要么要获得另一个(可在pascal，volta，turing上使用)的GPU，这些GPU可以在Windows上以TCC模式放置.

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，以获取有关如何以编程方式查询对以下内容的支持的说明:此功能.

Also refer to your other question for instructions how to programmatically query for support of this feature.
