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.
The CPU architectures are Non-Uniform Memory Access (NUMA) designs, such as those used in Intel Nehalem-based servers.
