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?

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.

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

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

  • Thanks for your reply. I think MX150 is a pascal architecture. I don't understand why my graphic card doesn't support. – pedram64 Dec 14 '18 at 15:54

    Because GeForce GPUs don't support TCC mode. That is by product design. There is nothing you can do about it. – Robert Crovella Dec 14 '18 at 15:55
