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:
“Thus for each blunt-faced ignorant one
The great grey rigid uniform combined
Safety with virtue of the sun.
Thus concepts linked like chainmail in the mind.”
—Thom Gunn (b. 1929)
“Language was not powerful enough to describe the infant phenomenon. “I’ll tell you what, sir,” he said; “the talent of this child is not to be imagined. She must be seen, sir—seen—to be ever so faintly appreciated.”... The infant phenomenon, though of short stature, had a comparatively aged countenance, and had moreover been precisely the same age—not perhaps to the full extent of the memory of the oldest inhabitant, but certainly for five good years.”
—Charles Dickens (1812–1870)
“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
