ETH PoW. When ETH switched to PoS, we shut it all down. It sure was fun while it lasted, not many people on the planet have run that much compute.

I did a lot of unique optimizations to autotune each individual GPU for performance by tweaking the software knobs on them. They are all snowflakes. Same model, different batches (heck, even same batch!), can produce wildly different performance results.

Over the years, I did try to find some alternative workloads for it, but nothing could even pay for the power costs. The GPUs were very old models (rx470-rx580) and the rest of the hardware wasn't that advanced, like it is in AI, so none of it was transferred.

I'm in the process of building my own AI supercomputer now. Really looking forward to seeing how it turns out.

Make a vid. Or a blog post, at least. Please :)

Thanks, but not my style, sorry! I've been doing PoW mining since 2014 and have so many stories, I've forgotten half of them. I wouldn't even know where to start on trying to document any of it.

Perhaps reach out to a YouTube channel or podcast that could be interested?

Did you manage to recoup the investment?

Of course I can't say anything about that other than I did the job I was hired to do, and I performed far above anyone's wildest expectations.

Nobody else on the planet was able to automate the tuning like I did, which had a direct influence on ROI. I know this because it required a very specific change to the AMD drivers to enable that functionality to happen.
