fit 4 platinum xeon in 1U?

[LukeP]

I am limited to 1U and want to fit as much CPU as possible. Are there any 4 Socket motherboards around? I can only find the SM ones that come with a server.

if i were to find a mb, where would i find a compatible psu? The SM motherboards have 7 x 6 pin plugs. Do retail psus come with so many plugs?

note i would fill it with ES or QS plats to save money so I am not interested buying expensive super-servers!

Thanks!

You mean a quad board ?
There is certainly systems that out 2 x dual boards in 1U. Not sure about a quad process or board that works for 1u...

 

[LukeP]

2 x dual boards is no good for my use. if they can make 2 x dual you would think they could make 4 1U. its even easier.

Quad-socket boards are generally very hard to find on the retail market. For LGA3467, I have not seen any.
I think your only option for now is buying a complete server.

 

[LukeP]

in your opinion, could i pull this apart Supermicro SYS-2049U-TR4 Quad Processor , and throw the mb and psu in to a 1U? its a bit rich just to harvest the mb/cpu. but since companies dont seem to offer what i want, what else can i do?

Supermicro SYS-2049U-TR4 Quad Processor

I think you will find that the heat output of 4x processors will overwhelm a 1U case.

We are working on a review of the SYS-2049U-TR4.

It is a proprietary motherboard where the PSUs attach directly to the motherboard. It may be possible, but very difficult. The SYS-2049U-TR4 is very cool though!

On the ES/QS CPUs, ES (QL) will likely not work. Maybe QS (QM/QN) will.

Just going to add here Supermicro | Products | SuperServers | 1U | 1029TP-DTR Would be what I would do for a 1U 4x CPU if you can get by with 2 systems.

You do not get full 12x DIMM per socket in 1U twin form factors.

I don't really understand why you'd get this over a 2U 4N but maybe, just maybe this is one of those use cases where it'd be better.

I want to know, why only 1U?!?!

 

[LukeP]

its simple, because where i want to stick it 1U costs $1200/month and 2U costs $2400/month

i cant get by with 2 systems. nano/microseconds matter.

gpus are a problem because of the slow kernel launch latency and pcie transfer latency

so.... big cpus with tight NUMA/QPI links are what i need.

 

[LukeP]

4 broadwells is also not as good as 2 xeon scalable. the scalable xeons have incredibly beasty FMAs. dual AVX-512

4 times the Zen+, so a pair of epics is also not as good as two scalables.

thats why i want 4 x skylake-x! .... awesome.

i think intel understands the way the world is headed better than amd.

 

[Evan]

High frequency trading related ?

 

[alex_stief]

i think intel understands the way the world is I am headed better than amd.

There, fixed that for you
Latency-bound applications are definitely not where the world is headed.

no, not latency bound... . vectorised maths. ie for machine learning.

Did you see the intel Xeon d-2100 AVX-512 performance even if single FMA, if you could squash a lot of them in (maybe not 1u but the supermicro blades that are verticalnin 3u I think) then odd as it may seem it may make sense if workload is easily distributed which maybe you case appears not)

If nanoseconds matter then are you sure you want a quad socket box? Qpi bus will jack up your latency. Best to stick to a single numa node for each workset...
