Thanks to @hackmod

You may pick up the binary from the build above. Although, an official release would be helpful.

I am also waiting for the official release for CUDA 11. It would be great when the dev team would make a new release.

The cuda10 version of this software can run with cuda11. I myself am running it with cuda11. And, of course, companies as big as Nvidia will make sure their driver is backward compatible.

What is your environment? I tried it with Windows 10 Pro, but unfortunately it gave CUDA not found errors.

WhymustIhaveaname commented 3 years ago

Linux with cuda11. I think it may be cuda installation problem. "Not found" is different from "wrong version."

Sorry, I meant invalid device symbol errors

It seems a common problem for 30xx GPUs. issue 2086 reports the same problem. Unfortunately, I have not got my 30xx GPU. So I hope that issue will help you.

Linux has no problem with cuda 11.2

codegastudio commented 3 years ago

On Jetson Xavier NX Work fine with cuda 10 but don't work anymore with cuda 11.2

ethminer 0.19.0-17+commit.ce52c740.dirty
Build: linux/release/gnu

CUDA Error : unknown error
Error: No usable mining devices found

Cuda 11 support NVIDIA Volta architecture which is the one used on Jetson Xavier NX.

I have already used your patch.

However, the mining speed is super super slow: A1 2.45 Mh - cu0 1.27, cu1 1.18

Any advice for that? Here is my log: https://paste.ubuntu.com/p/Fdb7y62cch

Thanks to @hackmod

Also BIG thx from my side @hackmod working like a charm with my 3080. Wonder if this was just a "one time help" or CUDA 11 will be added as additional Env on AppVeyor soon?
