OpenFOAM server for many small runs

Hi all,
I'm planning to purchase some hardware to run OpenFOAM simulations. These will be fairly small run-of-the-mill steady state RANS runs with grid sizes mostly below 1 million. However, there will be lots of these runs, i.e. many thousands. So this is less of an on-demand machine and more of a 24/7 number crunching device. Setup-wise, no regard needs to be placed on multi-user access. Considering the small size of these runs, memory bandwidth is probably more important than CPU freq or core count. So, a dual Epyc configuration with 2x32 cores and 8 DDR3200 DIMMs per socket is my baseline, assuming that the sub-million grid point cases are never too large for this. I've read up a lot on benchmarking and general setup, both in this board and elsewhere. With the background taken care of, I'd really appreciate some input regarding the following:
That's a lot of questions. I'm aware that some of these are a matter of personal preference, but I'm looking for general input. Any insight is much appreciated. Regards, awld |

Also, 3rd gen Epyc is already released. I would only buy second gen now if there was a substantial discount. Quote:

From their FAQ, they don't seem to do on-site support though. So if that's what you need, better look elsewhere. Last edited by flotus1; June 4, 2021 at 04:29. |
