AMD CodeXL is a software development tool suite that includes a GPU debugger, a GPU profiler, a CPU profiler and a static OpenCL kernel analyzer. AMD CodeXL is developed by AMD. == Features == GPU Debugger :AMD CodeXL’s GPU debugger allows engineers to debug OpenCL and OpenGL kernels: set breakpoints, step through source code in real-time, view all variables across different GPU cores during kernel execution, identify logic and memory errors, reduce memory transaction overhead, visualize OpenCL buffers and images and OpenCL textures as pictures or as spreadsheet data, and in this way to improve general software quality and optimize its performance. GPU Profiler :AMD CodeXL’s GPU profiler collects and visualizes hardware performance counters data, application trace, kernel occupancy, and offers hotspot analysis for AMD GPUs and APUs. The profiler gathers data from the OpenCL runtime, and from the GPU/APU itself during the execution of the kernels, and can be used to discover performance bottlenecks and optimize kernel execution. CPU Profiler :AMD CodeXL’s CPU profiling suite can be used to identify, investigate and improve the performance of applications, drivers and system software on AMD CPUs. AMD CodeXL’s CPU profiler uses a statistical sampling based approach with various profiling techniques and measures: Time-Based Profiling (TBP), Event-Based Profiling (EBP), Instruction-Based Sampling (IBS) and CPU hardware performance monitors. The AMD CodeXL CPU profiler replaces AMD CodeAnalyst Static OpenCL Kernel Analyzer :AMD CodeXL’s static kernel analyzer allows engineers to compile, analyze and disassemble OpenCL kernel code. The tool provides performance estimation for each kernel on different kinds of AMD chips, without actually executing the kernel. This way, the tool assists in kernel fine-tuning to achieve best performance on AMD GPUs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AMD CodeXL」の詳細全文を読む スポンサード リンク
