GPU Debugger o Support up to OpenGL 4.5 o Mouse hover displays variable value during kernel debugging CPU Profiler o CPU Profiling for the “Carrizo” APU o CPU Profiling on VMWare Support for SUSE 11 SP3 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 or later. Catalyst 14.12 (driver 14.501) is the recommended version. See "Getting the latest Catalyst release" section below. HSA Profiling o Supported on the Linux® HSA stack, on Kaveri and Carrizo APUs. o The May 2015 AMD release of the HSA runtime must be installed, available on GitHub here. o Should a new version of the HSA runtime become available, the version of the profiler included in CodeXL will need to be updated in order to be compatible with that version. 2 If/when a new runtime is published to GitHub, we will also publish new HSA Profiler binaries on the HSA-Profiler-AMD repository on GitHub (https://github.com/HSAFoundation/HSA-Profiler-AMD). In order to continue using the HSA Profiler with CodeXL, you will need to copy the following files from the GitHub repository to overwrite the versions of the files released with CodeXL: . bin/libGPUPerAPIHSA.so -> $(CodeXLDir)/x86_64/libGPUPerfAPIHSA.so . bin/libHSAProfileAgent.so -> $(CodeXLDir)/x86_64/libHSAProfileAgent.so . bin/libHSATraceAgent.so -> $(CodeXLDir)/x86_64/libHSATraceAgent.so . lib/libhsa-runtime-tools64.so.1 -> $(CodeXLDir)/x86_64/libhsa-runtime- tools64.so.1 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. CPU Profiling on VMWare o Time-Based Profiling (TBP) and Event-Based Profiling (EBP) are supported in guest OS running on VMware Workstation 11.0 or later. o If VMWare Workstations’s Virtual Performance Monitoring Counters (VPMC) is not supported on a given CPU, then only time-based profiling will be available. Event-Based Profiling will not capture any data other than CPU cycles. o Event-Based Profiling works on Windows andLinux guest OS in these scenarios: . Host OS: Windows, Guest OS: Window 7, Windows 8.1, Win10, Ubuntu 14.04, RHEL 7 . Host OS: Linux, Guest OS: Window 7, Windows 8.1, Win10, Ubuntu 14.04, RHEL 7 o Basic CPU configuration requirements: . CPU should support SVM or AMD-V feature. Without this VMware will not be able to do hardware virtualization. This CPU feature can be enabled/disabled from BIOS settings. Power Profiling o Supported on: . Carrizo, Kaveri, Mullins and Temash APUs. The majority of the Graphics IP 7 GPUs (code name “Sea Islands”) or more recent, including AMD Radeon™ and AMD FirePro™ models. Supported platforms: Windows platforms o Windows 7 64-bit, 8.1 64-bit and 10 64-bit. 3 o Note: For the CodeXL Visual Studio 2010/2012/2013 Package, the station must be installed with Visual Studio 2010/2012/2013, respectively. However, the CodeXL Standalone Application does not require Visual Studio to be installed. Linux platforms o Red Hat EL 7 64-bit o Ubuntu 14.04 64-bit o SUSE 11 SP3 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 Note about installing CodeAnalyst after installing CodeXL for Windows AMD CodeAnalyst has reached End-of-Life status and has been replaced by AMD CodeXL. CodeXL installer will refuse to install on a Windows station where AMD CodeAnalyst is already installed. Nevertheless, if you would like to install CodeAnalyst, do not install it on a Windows station already installed with CodeXL. Uninstall CodeXL first, and then install CodeAnalyst. Fixed Issues The following are the major fixes that were not part of the 1.7 release and are new to this version: Static Analysis runs out of memory and crashes while building and analyzing a CL file with over a hundred kernels that use OpenCL C++ templates. (287) In Analyze Mode, building a CL file with over 100 kernels succeeds but statistics and analysis are not displayed. (245) On Linux, the GPU Profiler displays empty Kernel Occupancy view if the occupancy percentage link is clicked twice. (249) GPU Debugger will not debug individual kernels included in programs whose total LDS usage exceeds 32KB. (243) On Linux, if CodeXL is launched via SSH and X-forwarding first in usermode and then in root mode, CodeXL aborts. (226) On Red-Hat 7, GPU Profiling Performance Counters of APP SDK samples SoAversusAoS, TransferOverlap and TransferOverlapCPP generates empty sessions. (233) On Red-Hat 7, the Kernel Occupancy column is not shown in GPU Profiling Performance Counters of APP SDK sample AsyncDataTransfer. (233) On Red-Hat 7 with Catalyst Omega 14.12, GPU Profiling Performance Counters of the APP SDK NBody sample may crash and exit. (233) Consecutively building many OpenCL files with the static analyzer leads to increased memory consumption and finally a crash. (275) GPU Debugger causes Visual Studio to hang when clicking the Locals view. (202) Mismatched CR/LF characters in the OpenCL kernel source code cause the debugger to show unrelated source lines when stepping through a kernel. (195) Multiple OpenCL kernels enqueued for debug concurrently may cause the debugger not to step into one of them. (162) 4 GPU Profiler occasionally does not generates kernel occupancy information during Performance Counters sessions. (159) CodeXL Remote Agent fails to connect when running on a headless Linux server. (145) GPU Debugger’s Properties view always shows workgroup size as 256. (139) GPU Debugger fails to build kernels for debug, causing the entire debug session to fail when debugging an application on a station installed with another vendor’s OpenCL runtime. (114) GPU Debugger’s Multi-Watch view displays class methods in its variable name drop-list. (122) 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. (334415) 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

  • 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.
