nikolaydubina/llama2.go: LLaMA-2 in native Go

This is a native Go inference of LLaMA-2, as of 2023-08-19 state-of-the-art open source large language model from Meta. It is ported from github.com/karpathy/llama2.c@bd18228 on 2023-08-19. Additional features may be added.

Note

2024-11-30 giving that performance is absolutely critical for LLM workloads, archiving this project until the time when Go CPU has comprable performance to C++ (e.g. vector instructions) and have native CUDA support

good morning said sun to trees: "Let's organize an operation!"
The trees clapped their branches and asked "What will we do?"
Badger smiled and replied "We will build a treehouse together!"
The trees got blocks of wood and started to build. Badger put nails in the tiny pieces of wood, while the trees put the blocks together to make a
 solid base. 
When they finished their treehouse, Goodger and the trees sat inside. Badger said, "Look how fancy we made it!"
The trees smiled and nodded. They said, "It's very fancy! Thank you for helping us organize this operation." 
Then they lived happily in their fancy treehouse together!

Once upon a time, there was a boy named Timmy. Timmy was very hungry and wanted to eat his meal. He asked his mom, "What are we having for dinner
?" His mom said, "We are having chicken and rice." Timmy said, "Yum! I love chicken and rice."
While they were eating, Timmy's dad came in and said, "Hey Timmy, do you want to watch a movie after

All optimizations are Fuzz-tested against basic algorithm, which is itself tested. To disable optimizations update llama2/transformer.go import to package without optimizations and rebuild.
