Hastega: Challenge for GPGPU on Elixir

Talk Description

We've succeeded in implementing a demonstration program in which an Elixir code invokes directly a GPGPU benchmark by Rustler. We propose a Hastega (Hyper Accelerator of Spreading Tasks for Elixir with GPU Activation) method that converts an Elixir code using Enum/Flow to an executable code for GPU or multi-core CPU with SIMD.

We've conducted a performance evaluation using the Logistic Maps of the experimental implementation of GPGPU using the Hastega method. We've got the following results:

  1. our Hastega is 4-8 times faster than pure Elixir executed by only CPU
  2. our Hastega is up to 3 times faster than CuPy/Python executed with GPU
  3. our Hastega is only 1.5 times slower than native code executed with GPU

Now, we implement Linear Regression and Neural Network in Elixir, and will accelerate it with Hastega. Our main future work is to implement a compiler from Elixir code with Enum/Flow to native code for GPU and/or multi-core CPU with SIMD.
