Hi,

I have recently joined an engineering consultancy and been tasked with implementing HPC resources in our team for future CFD analysis work. I have listed the specification below and would like your feedback if possible.

We will be using the computer to undertake single and multiphase, steady and transient analysis of pipework and valves this will also include some amount of FEA and FSI but primarily the hardware will be used for CFD, I think the meshes will be typically up to 40M cells worst case.

We will be using Ansys Fluent for the analysis and have 3 HPC packs so up to 132 cores available. We are UK based and have to use Dell as a vendor. I have discussed our requirements with Dell and we have came up with a spec, I would ideally like your feed back on the current configuration. At present we will only purchase 1 node but hopefully aim to expand this in future. This will be situated off-site and we will remote into it to run jobs.


CPU - 2x AMD Epyc 9334 (I have asked to swap this out for 2x 9354)
Memory - 24x 16GB RDIMM, 4800MT/s Single Rank
GPU - NVIDIA Ampere A2, PCIe, 60W, 16GB Passive, Single Wide, Full
Height GPU, V2
Boot Storage - BOSS-N1 controller card + with 2 M.2 480GB (RAID 1)
Storage - 8TB 7.2K RPM SATA 6Gbps 512e 3.5in Hot-plug Hard Drive

Thanks,

Steven

The 9354 is definitely a worthwhile upgrade here.
Other than that, Genoa-X has just been released today. These would be a significant upgrade again. But I doubt that Dell can sell them in the near future. It's worth asking though. 9384X would be the 32-core version.

That spinning hard drive though, not a fan for high-end computing. SSDs are way too cheap these days.

Ill will ask about Genoa-X and see what they say.

Yes it's probably worth swapping that out to an SSD as its only for short term storage.

Thanks
