'''Uniform Memory Access''' (UMA) is a [[shared memory]] architecture used in [[parallel computer]]s. All the processors in the UMA model share the physical memory uniformly. In a UMA architecture, access time to a memory ___location is independent of which processor makes the request or which memory chip contains the transferred data. Uniform Memory Access computer architectures are often contrasted with [[Non-Uniform Memory Access]] (NUMA) architectures. In the UMA architecture, each processor may use a private cache. Peripherals are also shared in some fashion,. The UMA model is suitable for general purpose and time sharing applications by multiple users. It can be used to speed up the execution of a single large program in time critical applications.<ref>Advanced Computer Architecture, Kai Hwang, ISBN 0-07-113342-9</ref>
