GSoC 2017: Creating the fastest math libraries for Ruby by using the GPU through OpenCL and ArrayFire.

[Prasun Anand]

Hi,

GSoC 2017 is upon us ;)

I have been working on ArrayFire-rb and took a break for a while exploring "D"

( Long time, no C :=)   ).

I would like to continue working on the ArrayFire wrapper, a GPGPU library for GSoC 2017.

I have already created MRI bindings for 2D matrices.

For GSoC period, I feel these would be the major goals:

1. Work on the JRuby bindings and implement other features for MRI(n-dimensional matrices). 

2. I would interface it with NMatrix and thus mixed_models.

3. The project would be centered around how efficiently can ArrayFire handle blog-data (real-life examples).

4. Test how ArrayFire-rb performs on Super Computers ( Max GFLOPS) ;)

5. By the end of GSoC, it would be great if I come up with some supercool examples using ArrayFire

    like an image recognition web app using ArrayFire.

 

Regards,

Prasun

Excellent. Glad to have you. :)

Thanks John and Charles :)

I am working on my application and trying to be as clear as possible with my plan for

the summer.

Hi,

Yesterday I ported ArrayFire to D.

All the features of ArrayFire were wrapped including Linear Algebra,

Computer Vision, Image Processing, etc. .

(OpenCL wrappers for D are available but they require a lot of effort

to work with[0],[1]).

Link: https://github.com/prasunanand/arrayfire-d/tree/devel

I have opened a PR and it is awaiting a review[2]. Meanwhile, I am working on examples and tutorials to release it as a dub package.

I didn't use any tool to generate the bindings because the C APIs and

C++ APIs of ArrayFire were in the same header files. I learnt a lot

about organising the APIs. It was a great experience and would certainly

help with ArrayFire Ruby bindings.

I have also found that ArrayFire Julia is undergoing a rewrite as there

were bugs due to memory leaks[3]. I would therefore take be a lot

careful while handling memory management and I am currently studying

about it.

Prasun
