NUMA-CIC
(pronounced
“numa-kick”)
NUMAScale Cache-coherent Inter-Connect for
exascale clusters
Proposal PRACE WP9 – Emerging Technologies Prototype
Hans Eide, PhD. USIT Research Computing Services Group.
Return of the SMP system, affordable and
scalable this time
•
•
A break-through design allows low latency, scalable, directory based
Cache Coherent Shared Memory interconnect of high volume
manufactured server boards, to be used as building blocks for systems
with features that are only found in the high-end enterprise capability
systems.
The proposal is to build a proof-of-concept prototype resource based
on this emerging technology for PRACE WP9.
Key objectives
•
•
To deploy a prototype cluster comprising both distributed-memory and
system-wide cache-coherent large shared memory (multiple
TeraBytes) based on NumaConnect technology.
The prototype will offer message passing as well as seamless scaling
with the shared memory programming paradigm
It exists, today!
