Multiple ARM CPU in the same Motherboard

Hi all

2 or 4 Intel XEON processors can be placed on the same motherboard, usually useful for Server applications

Is it possible to do the same with ARM CPU?

If so, which manufacturer supports that?

My purpose to to utilize a larger amount of ram for numerical heavy low power applications. I am lookign at TI DRA829J-Q1 (https://www.ti.com/product/DRA829J-Q1 ) processors. They seem to support only up to 8 GB.

My other need is that they should be able to NUMA aware linuxout of the box.

Also, are there some reference designs available for such motherboards ?

Thank you.
