## Minutes

### Rust_RL Supports Double-DQN

- https://github.com/ZuseZ4/Rust_RL/tree/ddqn
- https://medium.com/@parsa_h_m/deep-reinforcement-learning-dqn-double-dqn-dueling-dqn-noisy-dqn-and-dqn-with-prioritized-551f621a9823
- use two neural networks to predict a state

### rust_rl issue

- first open issue
- https://github.com/ZuseZ4/Rust_RL/issues/6

### from the rust_rl issue

- do we have that `rurel` tracked on arewelearningyet.com?
- https://github.com/milanboers/rurel/
- no, but last activity was August 2019

### New cifar-ten version released

- https://crates.io/crates/cifar-ten
- added an option to download the compress data (from online mirror)
- downloads and decompresses automatically

### tsuga

- chrism working on hardcoding a convolutional layer with backpropigation

### GPU

- any updates on OpenCL or webGPU bindings
- https://github.com/JonathanWoollett-Light/gpu_blas
- extreme WIP
- https://jonathanwoollett-light.github.io/blas/

### Automatic differenation of GPU Kernels
- https://github.com/wsmoses/Enzyme
- some successes!
- differenate matrix multiplies and some financial code and got the right anwsers
- you can `malloc` in a GPU kernel though it is very undocumented
- will give thread-level memory
- amount of memory per thread isn't equal to total GPU memory/number of threads
- Rust GPU code
- lookingo for good examples :P

### MPI handling
- in enzyme
- (MPI == message passing interface) for distributed computing

## Actions

- Get a gpu_blas update for next meeting
