I ready that its going to be used for AI related work if im mistaken?  What situations when it comes to AI does current hardware and GPU’s not manage to keep up in terms of running such networks?

There is the strange part. How to utilize such a vast cpu?
Storage should be the back end, unless the use is an api. In this case a gargantuan cpu sits in back, or so it seems.

There's more information here:


# Neocortex will use the HPE Superdome Flex, an extremely powerful,
# user-friendly front-end high-performance computing (HPC) solution
# for the Cerebras CS-1 servers. This will enable flexible pre- and
# post-processing of data flowing in and out of the attached WSEs,
# preventing bottlenecks and taking full advantage of the WSE
# capability. HPE Superdome Flex will be robustly provisioned with
# 24 terabytes of memory, 205 terabytes of high-performance flash
# storage, 32 powerful Intel Xeon CPUs, and 24 network interface
# cards for 1.2 terabits per second of data bandwidth to each
# Cerebras CS-1.

The way it reads both of these CS-1's will sit behind that single Flex.

All the best,
