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:
“We call ourselves a free nation, and yet we let ourselves be told what cabs we can and can’t take by a man at a hotel door, simply because he has a drum major’s uniform on.”
—Robert Benchley (1889–1945)
“Everybody’s an artist. Everybody’s God. It’s just that they’re inhibited. I believe in people so much that if the whole of civilization is burned so we don’t have any memory of it, even then people will start to build their own art. It is a necessity—a function. We don’t need history.”
—Yoko Ono (b. 1933)
“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)
