Today, both Intel and AMD use the
non-uniform memory access (NUMA) architecture in the multiple CPU chipset to achieve the best performance at a relatively low price.
The NAG SMP Library, recently updated to Mark 21, which is used by some of the world's most prestigious supercomputing centers was produced to enable developers and programmers to make optimal use of the processing power and shared memory parallelism of Symmetric Multi-Processor (SMP) or cache-coherent
non-uniform memory access (ccNUMA) systems.
These distributed shared memory systems are based on the company's NUMA 3 architecture, a third-generation
non-uniform memory access technology.
Finally, Belluzzo said that SGI will help develop Linux to the point where it supports ccNUMA (
non-uniform memory access).
The new eServer x430, a 64-way server with the new Intel 900 MHz (2) Pentium(R) III Xeon(TM) processor, offers industry leading
Non-Uniform Memory Access (NUMA) architecture and I/O technologies.
Processor performance will continue to evolve at the historical 30%-35% per year rate and make its gains through more appealing SMP (Symmetrical Multi-Processor) and NUMA (
Non-Uniform Memory Access) architectures.
