Unable to run with 40x512 networks. #70

Open therealkingoftheuniverse opened 2 years ago

therealkingoftheuniverse commented 2 years ago

Hello, When I try to run the engine using a 40x512 network, nibble will remain on "Awaiting readyok from engine" forever. If I try to use the engine in console mode, if I try a go command, the engine will load the network but then there will be no output the console won't let me type another line. Is there a way to fix this? Thanks in advance.

Lc0 with the same network seems to work fine. Ceres with 30x384 also works just fine. I am using RTX 3060 laptop GPU with 6gb vram.

Below is a screenshot of me trying to run it in console mode, its gets stuck at exactly that screen: image

Me too - I'm able to get some error messages though:

There are two issues here. First, as mentioned in the readme, currently Ceres only supports 40b networks on Ampere cards (e.g. 3080), not on the 20x0 series.

Even with 30x0 cards there can also be problems with 40b networks. We have determined that this depends on the NVIDIA driver; the most recent drivers will fail whereas the older ones (on which Ceres was originally tested) work fine.

Work is underway to understand and hopefully fix this later issue.
