Hello,

I’m new to CUDA’s Unified Memory and was trying to do some tests on my machine.
I have a GeForce RTX 3060 Laptop GPU with the latest drivers and CUDA computation capability version 8.6.
It seems that I have very low support for Unified Memory, concurrentManagedAccess has a value of 0.
The documentation indicates that Unified Memory is available since 5.0 and 6.0.

What could be the reason for this?

Thanks in advance.

If you are on Windows, then that is the reason. See here and here.

@rs277 Yes, I’m on Windows and I think this is the reason why I don’t have concurrent access to managed memory. Thank you.
