Introduction 1 Introduction 1.1 Overview The Intel ® Itanium ® Processor 9300 Series and Intel ® Itanium ® Processor 9500 Series employ Explicitly Parallel Instruction Computing (EPIC) design concepts for a tighter coupling between hardware and software. In this design style, the interface between hardware and software is designed to enable the software to exploit all available compile-time information, and efficiently deliver this information to the hardware. It addresses several fundamental performance bottlenecks in modern computers, such as memory latency, memory address disambiguation, and control flow dependencies. The EPIC constructs provide powerful architectural semantics, and enable the software to make global optimizations across a large scheduling scope, thereby exposing available Instruction Level Parallelism (ILP) to the hardware. The hardware takes advantage of this enhanced ILP, and provides abundant execution resources. Additionally, it focuses on dynamic run-time optimizations to enable the compiled code schedule to flow at high throughput. This strategy increases the synergy between hardware and software, and leads to greater overall performance. The Intel ® Itanium ® Processor 9300 Series and Intel ® Itanium ® Processor 9500 Series system interface, with its 4 full width and 2 half width Intel ® QuickPath Interconnects, enables each processor to directly connect to other system components, thus can be used as an effective building block for very large systems. The balanced core and memory subsystem provide high performance for a wide range of applications ranging from commercial workloads to high performance technical computing. The Intel ® Itanium ® Processor 9300 Series and Intel ® Itanium ® Processor 9500 Series are pin compatible and support a range of computing needs and configurations from a 2-way to large SMP servers (although OEM field upgrade methodologies vary). This document provides the electrical, mechanical and thermal specifications that must be met when using the Intel ® Itanium ® Processor 9300 Series and Intel ® Itanium ® Processor 9500 Series in your systems.
