With the 64000 Passmark cpu score, I'm having problems with 7532 performance in Fluent. With the same 1mil element setup, it has the same performance as Ryzen 5800x. With a 2d transient case, the more cores I use the worse performance gets, as seen on attached picture. It maybe a problem with Ansys 2022 R2, as it is shown here https://forum.ansys.com/forums/topic...ow-bandwitdth/. Unfortunately I cannot downgrade to 2020 R1 version. Have you seen something like this?
This is my setup: 1 SUPERMICRO MBD-H12DSi-N6-O Extended ATX Server Motherboard Socket SP3 2 2xAMD EPYC 7532 2.4 GHz 256MB L3 Cache Socket SP3 200W 100-000000136 Server Processor 3 128GB 16x16GB DDR4-3200 PC4-25600 1Rx4 RDIMM ECC Registered Memory by Nemix Ram 4 Dynatron A26 AMD Socket SP3 Aluminum Heatsink with Heatpipe Embedded 5 SAMSUNG 980 PRO M.2 2280 2TB PCIe Gen 4.0 x4, NVMe 1.3c Samsung V-NAND Internal Solid State Drive (SSD) MZ-V8P2T0B/AM 6 CORSAIR RMx Series (2021) RM1000x CP-9020201-NA 1000 W 7 NVIDIA Quadro M4000 8 GB GDDR5 |
