PPT-Multiprocessing and NUMA

What we sort of assumed so far Northbridge connects CPU and memory to rest of system Memory controller implemented in Northbridge chipset Devices and CPU can access memory via requests to Northbridge. g 03 Canonical example GPUs MIMD Multiple Instruction Multiple Data Ie 2 or more semiindependent CPUS 3 13 SIMD and MIMD Multiple CPUs come in several 64258avors SIMD Single Instruction Multiple Data Also called vector processor Sample instruction a e a circuit Pumps packet bits nonstop to destination No intermediate buffer Requires setup and teardown time Multicomputer Network Interface Interface boards usually contain buffer for packets Needs to control flow onto interconnection network when s Bruce Worthington.
