Writing Parallel Programs: a multi-language tutorial introduction


Introduction

Parallel programming was once the sole concern of extreme programmers worried about huge supercomputing problems. With the emergence of multi-core processors for mainstream applications, however, parallel programming is well poised to become a technique every professional software developer must know and master.

    Abstract

    Intel® SSE4 is a new set of Single Instruction Multiple Data (SIMD) instructions that will be introduced in the 45nm Next Generation Intel® Core™2 processor family (Penryn) and improve the performance and energy efficiency of a broad range of applications.

    Introduction

    This document details the difference between how assists are handled with x87 and Single Instruction Multiple Data (SIMD) instructions, and gives information on how to change their behavior when using (Streaming SIMD Extensions) SSE and SSE2.

    One of the consequences of the introduction of the Hyper-Threading technology into the Intel® Xeon® processor, is that systems with Hyper-Threading technology enabled appear to the Windows* operating system to have more physical processors than are actually installed. That is because with this technology, one physical processor will be seen as two logical processors. The term logical is used here to distinguish, for example, between the two logical processors in a system with one CPU and the two CPUs in a dual physical processor.
