Are the following configurations NUMA systems?

Hello,

Are any of the following 3 configurations NUMA systems?

1. Server Dell PowerEdge R530 - Rack 2U - 2x Intel Xeon E5-2620v3 6C/12T 2.4GHz, 8GB (1x8GB) DDR4-2133 RDIMM, DVD-ROM, 2x 300GB 10K SAS (max. 8 x 3.5" hot-plug HDD), RAID PERC H730 Ctrl 12GBps 1GB Cache, iDRAC8 Enterprise, Hot-plug PS (1+0) 750W, ReadyRails
2. Lenovo x3500 M5, 2x Xeon 6C E5-2609v3 6C/6T  85W 1.9GHz/1600MHz/15MB, 1x8GB, HDD 1TB 7.2K 6Gbps NL SAS 2.5in, SR M1215, Multi-Burner, 550W p/s, Tower
3. Lenovo x3650 M5, Form Factor 2U, 2x Xeon 6C E5-2620v3 85W 2.4GHz/1866MHz/15MB, 8GB 2133MHz LP RDIMM, SerrverRAID , M5210(no flash/cache), 2x300GB, HS 2.5in SAS(8), Multiburner, Power 2x550W HS PSU

If you have 2 sockets, you have non-uniform memory access.  Data transfer to/from the other socket's memory is higher latency and lower bandwidth than a local memory access.

Each of those systems has two Intel Xeon E5-2600 processors, one in each socket on the motherboard.

Any system that supports the E5-2620v3 processor should have two sockets, although it is not required to fill both sockets. And any Intel Xeon system with two processors will be a NUMA system, as the memory banks are connected directly to each CPU. Thus, part of the main system memory will always be assigned to different CPUs, which defines this as a NUMA system.

 Or how can you tell the number of sockets from the configurations provided?

Your configurations look like this

1. Server Dell PowerEdge R530 - Rack 2U - 2x Intel Xeon E5-2620v3 6C/12T 2.4GHz, 8GB (1x8GB) DDR4-2133 RDIMM, DVD-ROM, 2x 300GB 10K SAS (max. 8 x 3.5" hot-plug HDD), RAID PERC H730 Ctrl 12GBps 1GB Cache, iDRAC8 Enterprise, Hot-plug PS (1+0) 750W, ReadyRails

2. Lenovo x3500 M5, 2x Xeon 6C E5-2609v3 6C/6T  85W 1.9GHz/1600MHz/15MB, 1x8GB, HDD 1TB 7.2K 6Gbps NL SAS 2.5in, SR M1215, Multi-Burner, 550W p/s, Tower

3. Lenovo x3650 M5, Form Factor 2U, 2x Xeon 6C E5-2620v3 85W 2.4GHz/1866MHz/15MB, 8GB 2133MHz LP RDIMM, SerrverRAID , M5210(no flash/cache), 2x300GB, HS 2.5in SAS(8), Multiburner, Power 2x550W HS PSU

The emboldened 2x are what tell you that each of these configurations has two chips, and hence two sockets for them to sit in.

What I would like to know as well is:

1. What other processors besides Intel Xeon Phi are part of MIC Architecture?

2. Do all Intel Xeon processors support OpenMP or only Intel Xeon Phi?

Maybe I should open another topic for this, please advise to do so.

Thanks.
