  • An Introduction to Analysis and Optimization with AMD Codeanalyst™ Performance Analyzer
    An introduction to analysis and optimization with AMD CodeAnalyst™ Performance Analyzer Paul J. Drongowski AMD CodeAnalyst Team Advanced Micro Devices, Inc. Boston Design Center 8 September 2008 Introduction This technical note demonstrates how to use the AMD CodeAnalyst™ Performance Analyzer to analyze and improve the performance of a compute-bound program. The program that we chose for this demonstration is an old classic: matrix multiplication. We'll start with a "textbook" implementation of matrix multiply that has well-known memory access issues. We will measure and analyze its performance using AMD CodeAnalyst. Then, we will improve the performance of the program by changing its memory access pattern. 1. AMD CodeAnalyst AMD CodeAnalyst is a suite of performance analysis tools for AMD processors. Versions of AMD CodeAnalyst are available for both Microsoft® Windows® and Linux®. AMD CodeAnalyst may be downloaded (free of charge) from AMD Developer Central. (Go to http://developer.amd.com and click on CPU Tools.) Although we will use AMD CodeAnalyst for Windows in this tech note, engineers and developers can use the same techniques to analyze programs on Linux. AMD CodeAnalyst performs system-wide profiling and supports the analysis of both user applications and kernel- mode software. It provides five main types of data collection and analysis: • Time-based profiling (TBP), • Event-based profiling (EBP), • Instruction-based sampling (IBS), • Pipeline simulation (Windows-only feature), and • Thread profiling (Windows-only feature). We will look at the first three kinds of analysis in this note. Performance analysis usually begins with time-based profiling to identify the program hot spots that are candidates for optimization.

  • Instruction-Based Sampling: a New Performance Analysis Technique for AMD Family 10H Processors
    Instruction-Based Sampling: A New Performance Analysis Technique for AMD Family 10h Processors Paul J. Drongowski AMD CodeAnalyst Project Advanced Micro Devices, Inc. Boston Design Center 16 November 2007 1. Introduction Software applications must use computational resources efficiently in order to deliver best results in a timely manner. This is especially true for time-sensitive applications such as transaction processing, real-time control, multi-media and games. A program profile is a histogram that reflects dynamic program behavior. For example, a profile shows where a program is spending its time. Program profiling helps software developers to meet performance goals by identifying performance bottlenecks and issues. Profiling is most effective when a developer can quickly identify the location and cause of a performance issue. Instruction-Based Sampling (IBS) is a new profiling technique that provides rich, precise program performance information. IBS is introduced by AMD Family10h processors (AMD Opteron Quad- Core processor “Barcelona.”) IBS overcomes the limitations of conventional performance counter sampling. Data collected through performance counter sampling is not precise enough to isolate performance issues to individual instructions. IBS, however, precisely identifies instructions which are not making the best use of the processor pipeline and memory hierarchy. IBS collects a wide range of performance information in a single program run, making it easier to conduct performance testing. The AMD CodeAnalyst performance analysis tool suite supports IBS and correlates the instruction-level IBS information with processes, program modules, functions and source code. IBS in combination with CodeAnalyst helps a developer to find, analyze and ameliorate performance problems. This technical note is a brief introduction to Instruction-Based Sampling.

Abstract Graphics processing units (GPUs) of the current generation are highly programmable using interfaces like NVIDIA’s Compute Unified Device Architecture (CUDA) while of- fering a massive computational power for a relatively low price. The solution of systems of linear equations described by stencils representing finite element operators by iterative solvers is a application which can utilize these benefits of GPUs. This thesis describes the implementation of a parallelized Gauss-Seidel solver achieving up to 40 times the perfor- mance of a corresponding solver on standard CPUs. The solver is part of a library named GPUsolve, which offers the infrastructure to integrate this GPU-enabled application into object oriented C++ code. 4 Contents 1 Introduction 7 2 GPU Programming 8 2.1 GPU Hardware .................................... 8 2.2 Shader Programming ................................. 9 2.2.1 BrookGPU .................................. 10 2.2.2 Sh ......................................
