This project comes from the author of wyhash, which is now the default hashing algorithm in Go, Zig etc.
What's lacking is more information about the project. I was able to compile it and just started training on GPU, but I have no idea what's going on, when it will end, and what the characteristics are in general. Currently the only output I get is:
./train book-war-and-peace.txt
book-war-and-peace.txt 3.05397 1
para 1679360
32 1.3654 206.1985
I guess I need to dive into the source code in the meantime :)
