Non-Uniform Memory Architecture: Dual Processor AMD Opteron tested

Non-Uniform Memory Architecture (NUMA) as a special type of memory organization in multi-processor AMD Opteron platforms has been existing for a long time already — one can say since the announcement of AMD Opteron 200 and 800 that support multi-processor configurations. But we still haven't carried out a low level analysis of its advantages and disadvantages. That will be the subject of this article. Fortunately, our lab has a dual-processor system based on AMD Opteron CPUs. But at first let's revise the key features of this architecture. Read more at Digit Life.
