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...
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 ...
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...
pointer declaration to specify that data referenced by the pointer resides in global memory. For example, in the OpenCL C code at the end of the chapter,global int* Adenotes that the data pointed to byAresides in global memory (although we will see thatAactually resides in private memory)...
