trl0007 is on a distinguished road
At my work we are trying to find hardware in the ballpark of 10-15K that can effectively run a parallelized simulation that will at some point be asked to run refined 3-D cases with a chemistry model to model the mixing and combustion of fast moving gasses (near sonic velocities some of the times).

I understand that there is diminishing returns on the number of processor cores available to run in parallel, and I know there is a lot more to it than just that, so I figured I'd post some specs of a HPC we were quoted and see what you guys think:

Model: ACTserv x2110
Base system: Dual socket Xeon SP 2U system with 8x 2.5" drive bays
Omni-Path fabric integrated into processor: No
Processor: 2x Intel 12-Core Xeon Gold 6126 2.6GHz - 125W
Memory: 96GB - 12x 8GB DDR4 2666MHz
Storage configuration: 8x 2.5" SATA drives (software RAID only)
Storage 2.5" SATA: 2TB SATA 6Gb/s Enterprise 2.5" Hard Drive 7200RPM w/ 128MB Cache
Boot / OS drives: 2x 240GB Data Center SATA 2.5" Solid State Drive - RAID 1
Boot / OS drive location: Installed inside the system, not externally accessible
Networking: 2x RJ45 10Gb ethernet ports
OCP networking expansion: None
GPU configuration: 1x GPU
Management: Remote iKVM with in-band management
Power supply: Dual 1300W PSU (redundant)
Power cables: 2x 6ft NEMA 5-15P
Warranty: 3 year standard warranty
