Sonthun is on a distinguished road
I've been doing some searches to figure out what kind of hardware to buy to support OpenFOAM, but most of what I'm finding is about two years old. I wonder if all of you foamers could provide me with your experience using (if at all) the following items.

First, Is anyone using the Nvidia C2050 or C2070 Tesla GPU Computing Processors? If so how has it worked out for you? Was it worth the price? Can the 2050 and 2070 be combined in the same computer?

Second, what has been your experience with SSD's on OpenFOAM? Is anyone using them as RAM? If so how has that worked out?

Hopefully I'm not the only one asking these questions?

Thanks.

The standard installation of OpenFOAM does not support CUDA. However there are libraries to use linear solvers for GPU's. See for example http://speedit.vratis.com/

It looks like a poor idea to me, since SSD's have a limited number of read/write operation before failing, and the number of memory accesses in simulations is high.

Best,
