RapidCFD - OpenFOAM running on GPU

newoscar · April 9, 2015, 08:27

After weeks of hard work simFlow team made impossible become possible - OpenFOAM solvers are now able to run on CUDA! And that’s just for starters.

All the computation is done entirely on GPU. No need to copy data during calculations between CPU and GPU. All of this for getting the job done faster.

Features:

most incompressible and compressible solvers on static mesh are available
all the calculations are done on the GPU
no overhead for GPU-CPU memory copy
can run in parallel on multiple GPUs

I'm looking forward to the future with more codes running on the GPU. Good work and I'm staying tuned for future releases.

Greetings to all!

@Oskar: I noticed a news entry about this the other day and added RapidCFD to this wiki page: http://openfoamwiki.net/index.php/Forks_and_Variants

Can please also add RapidCFD to this wiki page: http://openfoamwiki.net/index.php/GPGPU - I ask this because I couldn't figure out the details of your implementation.

In addition, knowing which OpenFOAM version you've forked from, would come in handy.

Best regards,
Bruno

Great to see you guys interested in RapidCFD.
@wyldckat: sure, I'll add the details. As you said, it may come in handy. (it's OF 2.3.1 BTW)

Greetings to all!

Just to let you know that I've moved the discussions on how to install and use RapidCFD onto a new thread: Discussion thread on how to install and use RapidCFD

edit: A new prefix [RapidCFD] was open for RapidCFD at the OpenFOAM Community Sub-forum near the end of August 2018.

This way this current thread can be used mainly for announcements about RapidCFD.

Best regards,
Bruno

How mature is Rapid CFD, is there some progress done since the release 2015?

I do not understand why Open Source developers use CUDA?! I opened a new issue in your repository hoping one day it might be ported to OpenCL or any other vendor neutral API.

Is there any guidance to port new version of OpenFOAM (say OpenFOAM 4.x) to rapidCFD?
