Now that multi-core processors are becoming mainstream, developers need to thread their code so it will run in parallel. OpenMP1 can provide a useful way to thread an application. But what should you know about your threaded code’s performance, and what does that mean when using OpenMP? In an earlier paper2, we discovered that all threading methods have a consistent startup cost, but that OpenMP has some performance advantages over typical Windows* threading, due to its use of thread pooling. more>

This is the last of three white papers that teach you, an experienced C/C++ programmer, how to get started using OpenMP*, simplifying creation, synchronization, and deletion of threads in your applications. The first paper introduced you to the most common feature of OpenMP: work sharing for loops. The second paper taught you how to exploit non-loop parallelism and the usage of the synchronization directives. This final paper discusses the library functions, the environment variables, how to debug your application when things go wrong, and some tips for maximizing performance. more>

OpenMP provides a powerful, portable, and simple means of threading applications. In some cases, however, developers should choose the flexibility of native threading APIs. The guidelines in this article help to identify whether OpenMP is an appropriate choice for a given situation. more>

Dual-core and Quad-core processors are fast becoming the staple in desktop and mobile computing. In this article, performance data comparing single-threaded and multi-threaded matrix-vector multiplication are presented. In addition to multi-threading the routine, it was also optimized using Single Instruction Multiple Data (SIMD) instructions. The different implementations were tested on an Intel® Core™ 2 Extreme quad-core processor, QX6700. more>

Intel® Extended Memory 64 Technology (Intel® EM64T) is a 64-bit extension to Intel’s IA-32 architecture. Data can be accessed in 64-bit chunks, and large memory is addressable without special OS calls. This white paper introduces the architecture extensions and discusses performance tradeoffs when porting software from 32-bit to 64-bit. more>

Microprocessor performance has scaled over the last three decades from devices that could perform tens of thousands of instructions per second to tens of billions of instructions per second in today’s products. Our processors have evolved from super-scalar architecture to instruction-level parallelism, where each evolution makes more efficient use of fast single instruction pipeline. more>
