Need examples for GPGPU

[Erkaman]

Right now, there are not many examples that shows how regl can be used for GPGPU. But since regl greatly simplifies the usage of fbos, easy GPGPU is a great selling point of the framework, so we need good examples for it. Some possible examples are:

• Real-time radiosity.
• Sorting on the GPU.
• Implementations of simple GPGPU primitives, such as reduction, prefix sum, stream compaction, and so on.
• Liquid simulation on the GPU. As can be seen in this article, this is actually not very hard to do.
• Marching Cubes

And anyone who has implemented such an example is very much welcome to submit it, by a pull request!

Also a few to add:

• FFT
• Deep learning
• Particle physics demo

I am currently working on implementing some GPU primitives. Right now I am working on

• Parallel Reduction

Adding some references that may come in handy:

• Brook for GPUs: Stream Computing on Graphics Hardware
• A Survey of General-Purpose Computation on Graphics Hardware
• Building a Million Particle System - Presentation
• Building a Million Particle System - Paper

Adding some references for implementing Deep Learning:

• Short reference implementation in Python
• Deep Learning Tutorial Book
• Deep Learning Mit Book
• Convolutional Neural Networks
• Conv Nets: A Modular Perspective

[Erkaman]

Useful references for GPU sorting:

• GPU gems
• Implementation of Bitonic on GPU can be found here

I shall give implementing deep learning a try. To do that, I will first need to implement these two components on the GPU

• Convolution
• Matrix Multiplication.

Real time radiosity link

So I wrote a demo that does MNIST classification on the GPU: https://github.com/Erkaman/regl-cnn

It shows both how to implement convolution and matrix multiplication on the GPU.

We have some examples. I'm gonna close this since it is too vague.

I know some existing examples that I found useful https://github.com/sugeerth/pycuda
