OpenFOAM and CUDA
 

Dear All,

We announce that the SpeedIT Toolkit 0.9 has been released. The library has been internally deployed, tested and validated in a real scenario (blood flow in aortic bifurcation, data came from IT’IS Foundation, Switzerland).

http://vratis.com/speedITblog/

The library contains the CG and BiCGSTAB solvers and has been tested with Nvidia GTX 2xx and the newest Tesla.
The plugin for OpenFOAM is free and is licenced with GPL.

Currently we work on AMG and LB solvers which should appear in 2Q of 2010.

Best regards,
Lukasz

Hi, Lukasz,

Any update with the project?

Pei

Yes, the official release is there. See speedit.vratis.com for more details.

Are there any benchmarks for OpenFoam?

Yes. See Programmer's Guide in section "Documentation" for details. We did a test of a simulation of the blood flow in human aortic bifurcation using OpenFOAM.

Hi, Lukasz,

Is AMG included in the 1.0 release?

Is there any tutorials on how to get started? I have no experience with GPU computation. Any steps written describing how to use your software as OpenFOAM plug-in, and then, how to run it on GPU?

I would like to learn.

I downloaded and tried to open the sln file. It could not open it because it is trying to connect to local directory of computer it was developed on.

Other than that i looked at the code and i think i was doing the same as you guys have done except for one thing that you use cublas for dot product and norm etc , i do not use anything from cublas.

Still i hope that bug is fixed as i wish to see how this code compares with mine.

Hello,

I am a bit puzzled by the following notice on your "Download Classic" Web page: http://speedit.vratis.com/index.php/classic

About the not for commercial gain mention: do you mean commercial gain from redistributing your package, or commercial gain from using your package?

About the Binaries can only be used for non-commercial purposes mention: What binaries are you referring to?

What exactly am I going to download when I click either the "SpeedIT Classic 1.0" or "OpenFOAM plugin 1.0" button? Source code or binaries? This is not clear.

If I am indeed going to download source code released under the GPL license, are you restricting the usage I can do with the binaries resulting from compiling your source code?

I would appreciate if you could shed some light on this piece of text, knowing that you are releasing your source code under the GPL license, but by clicking on either those two download buttons, I also automatically acknowledge and accept some rather "confusing" and "unclear" terms and conditions.

Regards,

Martin

I m also interested

I'm also very interested.

Hi,
I want to mention that CUDA was a topic on OpenFOAM workshop OFW6 @ PennState
Implementing Fast Parallel Linear System Solvers In OpenFOAM based on CUDA
and much more at OFW7 in Darmstadt
http://www.openfoamworkshop.org/2012/OFW7_Program.html
see those CUDA presentations in HPC-Section (also SpeedIT presentation there)
