GPU in openFoam

30na · February 23, 2014, 06:47

Hi, I'm simulating a 3-D case in parallel using MrfInterFoam . but it's taking so long abd my instructor told me to get familiar with GPU running and run the program usuing this methos.
So could you help me with this matter and explain how to run programs in openFOAm with GPU . any help would be apperciates.

you need to have a cuda enabled gpu (an nvidia) then install cufflink and the latest extend version.

Hi everybody ,
I'm kinda new to OpenFOAM and I'm running a 3D case using MRFInterFoam , but it's taking too long and I've been informed that I can process my case much faster using GPU. I googled it but didn't find anything useful , can anyone give me some advice on how to install GPU for OpenFOAM ( i think it's a plug-in) , if you could give me a link it would be great.
and also if there is a tutorial on how to install and run a program with GPU i would be really grateful ! I'm really stuck ! Thanks in advance !

Greetings to all!

@30na: I've moved your post latest post to this thread, since you're the one who created it.

I've compiled today a page that lists the known available solutions: http://openfoamwiki.net/index.php/GPGPU
But keep in mind that if you don't have a really powerful GPU card (e.g. NVidia Tesla and Kepler), you're better off using multiple CPUs.

The easiest solution at this moment is to install foam-extend 3.0: http://wikki.gridcore.se/foam-extend/download
If you want more than one version of OpenFOAM working in your machine, read this page: http://openfoamwiki.net/index.php/In...with_the_Shell

Best regards,
Bruno

Is there any solution at the moment to use a NVIDIA Tesla K80 with OpenFOAM simulations that is free and uses double precision?

Hi,

You can compile Symscape's GPU solver library (http://www.symscape.com/gpu-1-1-openfoam) with double precision. Though the process is not quite pleasant, and you need to correct CMakeLists.txt files.

There is also RapidCFD - an open source project.
RapidCFD solvers can be used the same way as solvers in OpenFOAM. If you are familiar with the latter, you will find it easy to use.
The only thing that can be treated either as inconvenience or as easily adjustable is that you have to compile it by yourself. The whole process is described on wiki site of the project.
