NUMA Files are a type of file used in computing that optimize data access in systems with Non-Uniform Memory Access architecture. In these systems, memory access times can vary depending on the location of the data relative to the processor. NUMA files help manage this by organizing data in a way that minimizes latency and improves performance. These files are particularly useful in high-performance computing environments, where efficient data handling is crucial. By strategically placing data closer to the processors that use it most, NUMA files enhance overall system efficiency and speed, making them essential for applications that require rapid data processing.
