It does sound good.
I would guess you are looking are looking at using OpenFOAM for the CFD
One thing to look at though - how much RAM does each of these board
You might be better using the recipe for the cheap cluster on Doug
Eadlines Clustermonkey site.
By doing away with the cases they made a much cheaper cluster.
If you use standard-sized motherboards you might get cheaper parts to
And also have spare PCI clots for (say) a second gigabit network.
Pps. I hate to say this, but pragmatically with 6 of these boards you
get 12 times 1.6Ghz cores.
You can buy single workstations with eight cores of Nehalem at 2.6 Ghz
for not a lot of money.
You can still program these using MPI, and run Openfoam on them if your
aim really is to get runs done
For your MSc.
If on the other hand, you want to learn about clusters buy the boards
and let us know how it works!
