本文的异构计算平台的配置如下:硬件平台由AMD Bald Eagle和AMD FirePro W8100[11](或ES8950 MXM)组成,软件开发环境是Win7、AMD Catalyst 13.11以上版本和AMD APP SDK 2.8[12],编程语言及版本号是VC2010和OpenCL 1.2 C。图4是原始RGB图像、模拟数据和插值重建图像。三幅图像的尺寸均为1 920×1 080像素,有3个...
This is an OpenCL + OpenMP example. OpenCL program is running on the host, managing data transfers, and dispatching an OpenCL wrapper kernel to the device. The OpenCL wrapper kernel will use the ccode mode (see ccode example) to call the C function that has been compiled with OpenMP ...
其他程序测试方法跟以上一样,具体程序功能可以查看源码.C 文件的注释,路径在 Linux Processor-SDK安装包根目录“/example-applications/openmpacc-examples-1.4.0.2/”路径下。
This example demonstrates an efficient OpenCL implementation of parallel prefix sum, also known as "scan". Given an array of numbers, scan computes a new array in which each element is the sum of all the elements before it in the input array. Download - Windows (x86) Download - Windows...
搞定以后就可以开始写程序了。找到apple的一个例程:http://developer.apple.com/library/mac/#samplecode/OpenCL_Hello_World_Example/Listings/hello_c.html。 当然,我这非苹果的系统直接用这个是不行的。需要把#include <OpenCL/opencl.h>改为#include <CL/opencl.h>。apple的头文件目录和其他的平台有区别的...
