Dear All,

We are about to release a new version of OpenFOAM plugin aimed at acceleration of OF simulations on multi-gpu systems (also with single gpu).

I was wondering if OpenFOAM users have some special feature requests.
FYI, the plugin has the following functionality:

- It is a plugin and does not require to recompile OF. You just change one line in the configuration file and gpu-based solvers are used, if available.
- Currently, we also provide CG in single precision at no cost to demonstrate its usefulness but the plugin works with any gpu-based solver that produces matrices in CSR format.
- Note: We charge for CG/BCGSTAB in double precision and support. Installation of the free OF plugin will be quite simple.
- It will discover how many gpu cards the system has and will submit more intensive jobs to better cards.
- The plugin will be available at speedit.vratis.com
- So far we tested it with our solvers and we observed acceleration from several times on standard setup : GTX285+GTX460 to x38 on 4xTesla machines depending on the problem.

At speedit.vratis.com there is a forum where we have opened the discussion on feature requests. I am looking forward to meeting you there.
