Many of us are responsible for validating and testing Intel®-based designs. The latest Intel® Xeon® and Itanium® processor platforms use Intel’s QuickPath Interconnect (QPI) to tie the processor and the I/O hubs together into single, dual, and multi-processor systems. This book from Intel explains their technology...
