NUMAUnterstützung

NUMA Unterstützung refers to Non-Uniform Memory Access support in computer systems. NUMA is an architectural design for multiprocessing where memory access time depends on the memory location relative to the processor. In a NUMA system, processors are grouped into "nodes," each with its own local memory. Accessing local memory is faster than accessing memory in a different node, which is called remote memory. NUMA Unterstützung means that the operating system and applications are aware of this memory locality and can optimize performance accordingly.

Operating systems with NUMA Unterstützung attempt to allocate memory for a process on the same node as the processor executing that process. This minimizes the latency associated with accessing remote memory, leading to improved overall system performance. Software development also plays a role, as applications designed to be NUMA-aware can explicitly manage memory placement to take advantage of the architecture. Without NUMA Unterstützung, a system might distribute memory randomly across nodes, potentially leading to suboptimal performance due to frequent remote memory accesses. Modern multi-core and multi-processor systems often employ NUMA architectures, making NUMA Unterstützung crucial for efficient operation.
