The use of 2 or more central processing units in a single computer system
Flynn’s taxonomy distinguishes multi-processor computer architecture according to how they can be classified along the 2 independent dimensions of instruction and data.
SISD – single instruction single data
MISD – multiple instruction single data
SIMD – single instruction multiple data
MIMD – multiple instruction multiple data
In the UMA memory architecture, all processors access shared memory through a bus (or another type of interconnect)
Memory access time varies with the location of the data to be accessed. If data resides in local memory, access is fast. If data resides in remote memory, access is slower. The advantage of the NUMA architecture as a hierarchical shared memory scheme is its potential to improve average case access time through the introduction of fast, local memory.NUMA - Non-Uniform Memory Access
