Bulldozer Copy 1.2' title='Bulldozer Copy 1.2' />This document provides useful performance tips and optimization guidelines for programmers who want to use AMD Accelerated Parallel Processing to accelerate their applications. Audience. This document is intended for programmers. It assumes prior experience in writing code for CPUs and an understanding of work items. Prince Of Persia 3D Pc Game Download Full Version there. A basic understanding of GPU architectures is useful. It further assumes an understanding of chapters 1, 2, and 3 of the Open. The AMD Accelerated Processing Unit APU, formerly known as Fusion, is the marketing term for a series of 64bit microprocessors from Advanced Micro Devices AMD. Ive made my mind up to buy a small dozer over the winter. We just have to much dirt and stump work to do for us to try to use my TLB Kubota. Well, my Massey Ferguson 135 is getting pretty tired and blew the power steering pump last weekend. You never realize how important they are until they are down.

XL GPU Profiler hereafter Profiler is a performance analysis tool that gathers data from the Open. CL run time and AMD Radeon GPUs during the execution of an Open. CL application. This information is used to discover bottlenecks in the application and find ways to optimize the applications performance for AMD platforms. The following subsections describe the modes of operation supported by the Profiler. Collecting Open. CL Application Traces. This mode requires running an application trace GPU profile sesstion. To do this Sample Application Trace API Summary. Timeline View. The Timeline View See Sample Timeline View provides a visual representation of the execution of the application. Sample Timeline View. At the top of the timeline is the time grid it shows, in milliseconds, the total elapsed time of the application when fully zoomed out. Timing begins when the first Open. CL call is made by the application it ends when the final Open. CL call is made. Below the time grid is a list of each host OS thread that made at least one Open. CL call. For each host thread, the Open. CL API calls are plotted along the time grid, showing the start time and duration of each call. Below the host threads, the Open. CL tree shows all contexts and queues created by the application, along with data transfer operations and kernel execution operations for each queue. You can navigate in the Timeline View by zooming, panning, collapsingexpanding, or selecting a region of interest. From the Timeline View, you also can navigate to the corresponding API call in the API Trace View, and vice versa. The Timeline View can be useful for debugging your Open. CL application. Examples are given below. The Timeline View lets you easily confirm that the high level structure of your application is correct by verifying that the number of queues and contexts created match your expectations for the application. You can confirm that synchronization has been performed properly in the application. For example, if kernel A execution is dependent on a buffer operation and outputs from kernel B execution, then kernel A execution must appear after the completion of the buffer execution and kernel B execution in the time grid. It can be hard to find this type of synchronization error using traditional debugging techniques. You can confirm that the application has been using the hardware efficiently.
