Hi,

we are looking for a new rack-mounted workstation in our (small) company to enhance our computing power.
The main tasks will be:
- ~80% CFD calculations with OpenFOAM, mesh size 2-25 millions cells, mostly simpleFoam/pisoFoam, interDyMFoam and chtMultiRegionSimpleFoam.
- 20% FE Analysis, both implicit and explicit, using max 8 cores.

The key features for the workstation will be:
- 2 x Xeon E5 v3 cpus
- 256 GB DDR4 RAM
- SSD + HDD
- basically no graphic power, as the visualization will be done on other workstations


Regarding our area of application, various cpus come into question that are pricely viable:
- 2x Xeon E5-2667 v3: 16 * 3.2 GHz
- 2x Xeon E5-2687W v3: 20 * 3.1 GHz
- 2x Xeon E5-2690 v3: 24 * 2.6 GHz
- 2x Xeon E5-2697 v3: 28 * 2.6 GHz

Which one would be the best choice or are there any other cpus that are even better, considering both the price/performance and the viability to run small jobs (~ 5 mio cells) with a decent performance?


Thanks!
