家做cluster的，他们报的配置如下（基于相同的预算）：
Cluster 1:
8 compute nodes @ 128 cores
Processor: Intel XEON e5-2667 v4 CPU (3.2GHz/3.6GHz HT) (16 X 8c)
Chassis: 4 x 1U x 2 Node chassis (1000 Watt power supply)
Memory: 8 x 128 GB DDR4-2400MHz LRDIMM (8 X 16 GB)
OS Data: 8 x 2 x 1TB SATA 7200 RPM 6Gbp/s
Interconnect: 8 x 56 Gbps Infiniband
Interconnect Switch: 12 port Mellanox FDR switch
Operating System: CENTOS 7
Cluster 2:
8 compute nodes @ 192 cores
Processor: Intel Scalable Xeon SKL-SP GOLD 5118 12C/24T 2.3G 16.5M 10.4GT
UPI
Head Node: 8 cores (2 x SILVER 4112), 96GB Memory (6 x 16GB) DDR4 ECC RDIMM,
32TB Storage (8 x 4TB) RAW-RAID 10/5/6 all available 9SAS3 Discrete RAID)
Each Compute Node: 24 cores ( 2x GOLD 5118), 192 GB Memory (12x 16GB) DDR4
ECC RDIMM 2666MHz
Interconnect: 36 port EDR InfiniBand Switch from Mellanox
24 Port Management Switch
Operating System: Read Hat Enterprise Linux
请问大家哪个对CFD计算更给力？ 对第2个cluster, 目前由于软件的原因，只能利用其
中的128个核。本人不懂硬件，谢谢大家发表意见。 | f*****r

你们公司还招CFD计算的吗？能内推一下吗？ |
