'''Uniform memory access''' ('''UMA''') is a [[shared memory architecture|shared memory]] architecture used in [[parallel computer]]s. All the processors in the UMA model share the physical memory uniformly. In an 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 UMANUMA 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 [[real-time computing|time-critical]] applications.<ref>Advanced Computer Architecture, Kai Hwang, {{ISBN|0-07-113342-9}}</ref>
