Excellent Overview of NUMA

By boristheblade     Nov 7, 2006 in Technology
A good introduction to non uniform memory access pros/cons for developers. It should be interesting to see Intel's solution (if they ever come up with one that works) or if they will end up licensing AMD's Hypertransport.
While AMD certainly isn't the only microprocessor manufacturer to support multiprocessor systems, it offers a unique performance advantage due to its Direct Connect Architecture. Each processor contains its own integrated memory controller, and each processor core has its own L1 and L2 cache. A core is the central processing unit. A single-cored microprocessor has one CPU in the silicon; a multi-core processor has multiple CPUs in the actual chip.
