Use Accelerad

[agonzalezesteve]

Accelerad is suite of programs that improves ray tracing algorithms using an engine for GPU (now it's in a beta version).

I propose using this engine to accelerate simulations.

Hello Adria,

I am happy to do that. However, I would argue that this needs to be done properly because not all computers can run Accelerad (only NVidia ones), am I right?

On the other hand, even if I believe Accelerad's license is OK with this use, we should check that.

So, two options:

1. Create an option (i.e. configuration) that allows "enabling Accelerad"
2. Create another version of Radiance that relies on Accelerad

I like option number 1 better. Unfortunately, I cannot help you test it, because I do not have NVidia graphics card.

It should be easy to implement Accelerad here... it is a matter of replacing the corresponding programs with the Accelerad ones. However, in order to make this optional, we need to somehow allow "choosing" a certain program (e.g.rtrace = accelerad_enabled ? "rtrace" : "acc_rtrace").

If you need any help, let's keep this thread going

With this https://rocm.github.io you can hypothetically run CUDA code on AMD GPU as well if the platform is modern enough (CPU: Haswell or Ryzen, GPU: from R9 3XX GCN 2.0). I think they are back porting this to support more somewhat older platform as well.

That looks extremely cool! Unfortunately, right now I do not have time to work on that... but I will definitely check it out

I might work on this in December/January as I'm designing my house and I have an nvidia card, hopefully it won't be too hard. Accelerad uses nvidia OptiX extension so it might not be compatible with ROCm (yet) though.

Please do it within the Emp-core <https://github.com/GroundhogLighting/emp_core/>! The plan is to migrate there....Groundhog 1.0b is using Emp as the calculation engine El mié., 7 nov. 2018 a las 10:16, Minh Ha (<notifications@github.com>) escribió:

And thanks! It would be really cool if you could do it. El mié., 7 nov. 2018 a las 10:27, Germán Molina Larrain (< germolinal@gmail.com>) escribió:
