Uniform Memory Access (UMA) is a shared memory architecture used in parallel computers.
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.

Famous quotes containing the words uniform, memory and/or access:
“The maples
Stood uniform in buckets, and the steam
Of sap and snow rolled off the sugarhouse.”
—Robert Frost (1874–1963)
“Ah! you can die, the world can collapse, I have lost the one I love. I must now live in this terrible solitude where memory is torture.”
—Albert Camus (1913–1960)
“The professional celebrity, male and female, is the crowning result of the star system of a society that makes a fetish of competition. In America, this system is carried to the point where a man who can knock a small white ball into a series of holes in the ground with more efficiency than anyone else thereby gains social access to the President of the United States.”
—C. Wright Mills (1916–1962)
