Corlin Palmer's Go solution to the 1BRC coding challenge: https://github.com/gunnarmorling/1brc

- This solution reads the file sequentially as fast as possible (reader)
- It passes off the job of ensuring that each chunk ends with a complete line to another goroutine (lineSupervisor)
- The lineSupervisor sends valid chunks to a pool of worker goroutines (worker) which parse the data and calculate the results
- The results from the workers are collected in a map and then sorted before printing the final results

A fair amount of optimization has been done to reduce memory allocations.

Automating Daily Reports, because fuck it, really...

Each day at our company, developers are required to document their activities, painstakingly jotting down their daily work and future plans. A monotonous chore that I just really dislike.

So now, there's a scribe for that :

Code

This worked on 14/May/23. The instructions will probably require updating in the future.

llama is a text prediction model similar to GPT-2, and the version of GPT-3 that has not been fine tuned yet. It is also possible to run fine tuned versions (like alpaca or vicuna with this. I think. Those versions are more focused on answering questions)

Note: I have been told that this does not support multiple GPUs. It can only use a single GPU.

It is possible to run LLama 13B with a 6GB graphics card now! (e.g. a RTX 2060). Thanks to the amazing work involved in llama.cpp. The latest change is CUDA/cuBLAS which allows you pick an arbitrary number of the transformer layers to be run on the GPU. This is perfect for low VRAM.

• Clone llama.cpp from git, I am on commit 08737ef720f0510c7ec2aa84d7f70c691073c35d.
