NUMA Architecture, or Non-Uniform Memory Access, is a computer memory design used in multiprocessor systems. In this architecture, each processor has its own local memory, but can also access memory from other processors. This setup allows for faster access to local memory, improving performance for applications that require high-speed data processing. In NUMA, the memory access time varies depending on the location of the memory relative to the processor. This means that accessing local memory is quicker than accessing memory from another processor. NUMA is commonly used in high-performance computing environments, where efficient memory management is crucial for performance.
