Non-Uniform Memory Access

(architecture)
(NUMA) A memory architecture, used in multiprocessors, where the access time depends on the memory location. A processor can access its own local memory faster than non-local memory (memory which is local to another processor or shared between processors).

Shared-memory multiprocessors cover a wide range of prices and features, from commodity SMPs to large high-performance cc-NUMA machines.
In these designs, accessing main memory has nonuniform access costs to a processor and in this way, architectures of this type are often called cache-coherent, nonuniform memory access or cc-NUMA architectures.
This will be the fourth SPP product based on a hardware-based CC-NUMA architecture called Global Shared Memory, which is far ahead of any competitive platform," Bemis said.
With the SPP architecture, we are far ahead of any competitive platform, and scalable parallel processing based on CC-NUMA is rapidly becoming the industry standard," Wallach said.
Silicon Graphics' Origin2000 utilizes an advanced version of CC-NUMA architecture that provides scalability, availability, high bandwidth/low-latency data handling, cost effectiveness and other advanced features over a wide range of price points.
Origin servers are based on breakthrough CC-NUMA (cache-coherent Non- Uniform Memory Access) technology that, combined with modular, expandable bandwidth and the fastest I/O available, makes Silicon Graphics(R) servers key to the success of data-intensive computing environments.
The converged product lines (scalable vector and highly scalable microprocessor-based systems) will incorporate Silicon Graphics' next-generation CC-NUMA architecture, scalable IRIX with Windows NT interoperability and cost-effective CMOS technology involving the deployment of both custom and Intel processors.
We look forward to a continued collaboration with NRL to extend the capabilities of Origin server's CC-NUMA architecture even further.
Origin200 QC shares the CC-NUMA architecture, I/O system, and memory
The Silicon Graphics Origin200(TM) and Origin2000(TM) servers with their scalable CC-NUMA architecture, fast 64-bit RISC processors, and revolutionary I/O subsystem are uniquely suited to manage large amounts of data reliably and quickly.
The cc-NUMA Origin server line, scaling from one- to 128-processor configurations, leads the industry in performance, scalability, bandwidth, I/O and cost structure.
