Pelemay (formerly Hastega) - Challenge for GPGPU on Elixir!

Do you want to learn and use machine learning in Elixir / Phoenix / Nerves apps? Of course, you can, but the machine learning is written in Python and invoked from Elixir via ErlPort… Of course, you can implement some machine learning algorithms in Elixir. However, they have no computational power enough to execute real applications. We wish Elixir could have more computational power!

This may change by Hastega! Hastega will make a series of code fragments of pipelined Enum.map to be transformed into optimized native code using GPUs and/or CPUs with SIMD instructions.

I wrote a post of Medium on Hastega:

Really?
I wrote the same URL to the post on SNSs, which works well…

I’ve said it before but will say it again, can’t wait to hear more about Hastega - keep up the good work! :023:

Just discovered Hashtega and it sounds really exciting. Any news?

Pelemay 0.0.6 has been released!

A new feature of this release is to support String.replace.

defmodule M do
require Pelemay
import Pelemay

defpelemay do
def string_replace(subject) do
String.replace(&1, “Fizz”, “Buzz”)
end

def enum_map_string_replace(list) do
  list
  |> Enum.map(& String.replace(&1, "Fizz", "Buzz"))
end

end
end

This code is 4x faster than original Elixir code.

StringReplaceBench

benchmark name iterations average time
Pelemay String.replace 1000000 1.20 µs/op
Enum String.replace 500000 3.92 µs/op
Flow String.replace 5000 678.27 µs/op
