Dear Members,


I want to build a 128 cores hardware to use with ANSYS solvers (mainly FLuent, and a bit Mechanical) with 3 HPC packs licenses (go up to 128 cores on a single calculation).
In my understand, nowadays AMD Epyc Milan processors are much more interesting than the Intel Xeon Ice Lake ones (better performance/price ratios).

My company IT supplier is DELL. Dell propose a 2 sockets rack servers where one can have for example 2x 7763 processors, with 16x32GB of DDR4 RAM (use the 2x8 memory channels of the CPUs). And with 2x 6.4 Tb NVME mixed use SSDs.

In the CFD-online forum, I never saw an Epyc 7763 hardware configuration. I don't know if it is a price matter or a performance one.

One can also think to build a 2 compute nodes with 2 CPU each and then have for example 2x2xEpyc 7543 CPUs (128 cores to use the 3 ANSYS HPC pack licenses simultaneously). But the inconvenient point is that we will have to interconnect the 2 compute nodes and we don't have any experience to manage cluster architecture (with the single compute node with 2x7763, we have nothing to manage).


Can you give an advice if a 2x 7763 configuration is a good choice ?


Ps: My plan is to invest on the next year Epyc Genoa generation (DDR5, 12 memory channels, ...), still the Milan one is a good parallel.

Thank you in advance for you help !
