AMD Codexl 1.3 GA Release Notes AMD CodeXL 1.3 GA Release Notes Thank you for using CodeXL. We appreciate any feedback you have! Please use the CodeXL Forum to provide your feedback. You can also check out the Getting Started guide on the CodeXL Web Page and the latest CodeXL blog at AMD Developer Central - Blogs This version contains: For Windows for 32-bit and 64-bit Windows platforms o CodeXL Standalone application o CodeXL Microsoft® Visual Studio® 2010 extension o CodeXL Microsoft® Visual Studio® 2012 extension o CodeXL Remote Agent For 64-bit Linux platforms o CodeXL Standalone application o CodeXL Remote Agent Note about 32-bit Windows CodeXL 1.3 Upgrade Error On 32-bit Windows platforms, upgrading from CodeXL 1.0 using the CodeXL 1.3 installer will remove the previous version and then display an error message without installing CodeXL 1.3. The recommended method is to uninstall previous CodeXL versions before installing CodeXL 1.3. If you ran the 1.3 installer to upgrade a previous installation and encountered the error mentioned above, ignore the error and run the installer again to install CodeXL 1.3. Note about installing CodeAnalyst after installing CodeXL for Windows CodeXL can be safely installed on a Windows station where AMD CodeAnalyst is already installed. However, do not install CodeAnalyst on a Windows station already installed with CodeXL. Uninstall CodeXL first, and then install CodeAnalyst. System Requirements CodeXL contains a host of development features with varying system requirements: GPU Profiling and OpenCL Kernel Debugging o An AMD GPU (Radeon HD 5000 series or newer, desktop or mobile version) or APU is required. o The AMD Catalyst Driver must be installed, release 13.11 Beta or later. Catalyst Beta 13.11 is the recommended version. See "Getting the latest Catalyst release" section below. For GPU API-Level Debugging, a working OpenCL/OpenGL configuration is required (AMD or other). CPU Profiling o Time-Based Profiling can be performed on any x86 or AMD64 (x86-64) CPU/APU. o The Event-Based Profiling (EBP) and Instruction-Based Sampling (IBS) session types require an AMD CPU or APU processor. Supported platforms: Windows platforms o Windows 7, 8 and 8.1, 32-bit and 64-bit o Visual Studio 2010/2012 must be installed on the station before the CodeXL Visual Studio 2010/2012 Package is installed, respectively. o If Visual Studio 2010 is not installed, the VC++ 2010 x86 Redistributable package must be installed for CPU Profiling Source View of .NET applications to work. Linux platforms o Red Hat 6 u3 64-bit o Ubuntu 12.04 64-bit Getting the latest Catalyst release The way to get the latest beta driver is to use the links "Latest Windows Beta Driver" and "Latest Linux Beta Driver" on the Graphics Drivers support page: http://support.amd.com/us/gpudownload/Pages/index.aspx New in this version The following items are new in this version: CodeXL includes a Remote Agent application for Remote GPU Profiling and Remote GPU Debugging. Developers can now run the CodeXL client application on their development station and launch their product application for GPU debugging or profiling on a separate target platform such as a server node. The AMD APP KernelAnalyzer application is now obsolete. Instead, CodeXL delivers a brand new user experience for Static OpenCL Kernel Analysis as part of the CodeXL application, encapsulated under a new work mode named Analyze Mode. This includes activation of the OpenCL offline compiler and detailed emulation of kernel performance resulting in analysis of multiple flow paths. The offline kernel performance analysis has been extended and supports target devices from the Southern Islands (Radeon HD 7000 series) and Sea Islands (Radeon HD 8000 series) families of GPUs. CPU Profiling of Cache Line Utilization. Developers can now use CodeXL to profile the utilization of the CPU's cache. CPU Profiling support for Java inline functions. New design for the CPU Profiling Source Code /Disassembly View. GPU Debugging support for OpenGL 4.3. Support includes coverage of API functions and objects new in OpenGL releases up to and including 4.3. Support for the complete set of OpenCL 1.2 data types and API. Fixed Issues The following fixes were not part of the 1.2 release and are new to this version: Visual Studio crashes on launch after re-naming a GPU Profiling session and deleting it. (405809) While GPU Debugging, CodeXL points to incorrect source line on first step into kernel.

(406284) Debugged application crashes when exiting. (363607) In GPU Debugging, stepping through some OpenCL kernels advances to non-sequential source lines. (396656, 404045, 387422) - fixed in Catalyst driver 13.8 Building an OpenCL kernel in Analyze mode (formerly KernelAnalyzer) - further builds are not allowed after the offline compiler reports "clBuildProgram had an unhandled exception". (399444) - fixed in Catalyst driver 13.11 Beta Building an OpenCL kernel analysis in Analyze mode (formerly KernelAnalyzer) won't show ISA tab/code for Devastator and Scrapper GPUs. (403765) - fixed in Catalyst driver 13.8. Building a kernel in Analyze mode (formerly KernelAnalyzer) doesn't generate ISA code for CPU target device. (398323) - fixed in Catalyst driver 13.11 Beta OpenCL kernel analysis in Analyze mode (formerly KernelAnalyzer) shows all zeros for Oland target devices. (399435) Building a kernel which uses double precision in Analyze mode (formerly KernelAnalyzer) causes "Frontend phase failed compilation" error. (401636) Building the APP SDK AtomicCounters kernel in Analyze mode (formerly KernelAnalyzer), fails to generate IL/ISA. (406669) Building the APP SDK BlackScholesDP kernel in Analyze mode (formerly KernelAnalyzer) fails. (406673) During GPU Debugging, Visual Studio may stop responding when kernel debugging while a window displaying an OpenGL object is open. (385320) During GPU Debugging, adding a large number of Breakpoints makes Visual Studio slow or sometimes unresponsive. (404178) CPU Profiling on Intel i7 Ivy Bridge may cause a system crash (BSoD). (405682) In CPU Profiling mode, importing a thread-based session generated from CodeAnalyst sometimes results in CodeXL crash. (356479) CodeXL crashes when performing CPU: Assess Performance profile of APP SDK sample LUDecomposition. (394149) For CPU Profiling sessions that include Call-Stack Sampling, CodeXL may hang during the post- processing stage. (406095) After performing CPU Profiling of OpenCL applications, post processing takes a very long time. (369505, 387530) On Linux, CPU Profiling Instruction-Based Sampling sessions of Java applications may attribute event samples to libjvm. (403250) When viewing a CPU Profiling session, choosing to display data per core / per node causes columns that were not selected for display to be shown. (403724) When viewing a CPU Profiling session, selecting a module and clicking "Display in Functions View" command, the functions view's Modules Filter should contain only the selected module. (404154) No CodeXL icon in Ubuntu dashboard panel & alt + tab list. (404193) Viewing CPU Profiling session data on Linux, Call Graph view shows Self/Deep samples but the functions and Overview tables are empty. (404458) In GPU Profiling, navigation to Source Code does not work for GL samples. (404851) CodeXL installer should install the Visual C++ redistributables if Visual Studio 2010 or later is not installed. (404870) GPU Profiler reports 0 for all performance counters of APP SDK QuasiRandomSequence on Cape Verde platforms (357699) When navigation to source code is enabled in GPU Profiling Application Trace profiles, navigation to source code would not work for later API calls in the session (404851) GPU Debugging on Linux, if gdb reports an error, CodeXL should realize the application has terminated. (405281) The GPU Debugger shows a type of unnamed struct for variables of the built-in type int4. (362152) On Linux with KDE, while GPU Debugging, the debugger displays static buffers, textures and VBOs in the explorer tree but won't show their content in the Object views. (406260) Building a kernel in Analyze mode (formerly KernelAnalyzer), the ISA window shows ALU packing and ALU clauses as "(0.0)" for all Northern Islands (Radeon HD 6000 series) GPU Cards. (344059) On Linux with KDE, CodeXL becomes unresponsive after opening User Guide/ Quick-Start Guide / Forum, when as the root user. (406604) CPU Profiling on Linux does not always contain call stack information - Call Graph view shows empty parents table and call graph tree. (388188) Known Issues Debugging OpenCL kernels that use read-modify-write atomic operations is not supported. GPU Debugging on OpenCL Static C++ Kernels is not supported. (345852) __read_only and __write_only Image variables are not shown in locals during GPU Debugging. (345852) OpenCL 1.2 keyword printf and barriers are not supported during kernel debugging. Building kernels with OpenCL 1.2 clCreateProgramWithBinaries and clLinkProgram API prevents the display of source code when debugging these kernels. (369171) Performing CPU Profiling with Call-Stack Sampling (CSS) enabled, on systems with discrete graphics card (Radeon HD 5000, 6000 or 7000 series) and Linux kernel version 3.0 or lower, may result in Linux kernel panic. This kernel panic does not occur with Linux kernel version 3.2 onwards. (352399) CPU Profiling on Linux platforms - Limitations of PERF o CPU profiling uses PERF which requires kernel 2.6.32 or later. CPU Profiling with Call Stack Sampling requires Linux kernel 3.0 or later. However, we recommend using kernel 3.2 and above which has shown to be more stable. o Call chain analysis on Linux currently depends on the call chain information provided by Linux PERF.

  • 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.

Bardzo często grafika komputerowa jest kojarzona z urządzeniem wspomagającym jej generowanie - kartą graficzną, odpowiedzialna za renderowanie grafiki oraz jej konwersję na sygnał zrozumiały dla wyświetlacza 1. Historia Historia Historia kart graficznych sięga wczesnych lat 80-tych ubiegłego wieku. Pierwsze karty graficzne potrafiły jedynie wyświetlać znaki alfabetu łacińskiego ze zdefiniowanego w pamięci generatora znaków, tzw. trybu tekstowego. W późniejszym okresie pojawiły się układy, wykonujące tzw. operacje BitBLT, pozwalające na nałożenie na siebie 2 różnych bitmap w postaci rastrowej. Historia Historia #2 ● Wraz z nadejściem systemu operacyjnego Microsoft Windows 3.0 wzrosło zapotrzebowanie na przetwarzanie grafiki rastrowej dużej rozdzielczości. ● Powstaje interfejs GDI odpowiedzialny za programowanie operacji związanych z grafiką. ● Krótko po tym powstały pierwsze akceleratory 2D wyprodukowane przez firmę S3. Wydarzenie to zapoczątkowało erę graficznych akceleratorów grafiki. Historia #3 ● 1996 – wprowadzenie chipsetu Voodoo Graphics przez firmę 3dfx, dodatkowej karty rozszerzeń pełniącej funkcję akceleratora grafiki 3D. ● Powstają biblioteki umożliwiające tworzenie trójwymiarowych wizualizacji: Direct3D oraz OpenGL.
