Question

您好我正在学习openCL并遵循一本书的示例并尝试执行以下操作

//Obtain the GPU data (platform, device and context)
PlatformDevice gpu = retrieveDevice(CL_DEVICE_TYPE_GPU);
assert(gpu.allDat![enter image description here][1]aPresent());
const char * kernalSource = "__kernel void multiplication(__global float* GridA, __global float* GridB,__global float* val ){int igrid = get_global_id(0);float a = GridA[igrid];float b = GridB[igrid];val[igrid] = a * b;}";

//Create Program
cl_program program = clCreateProgramWithSource(gpu.context,1, (const char**) kernalSource,NULL,&err);

当我到达最后一行时，它会产生以下错误

Unhandled exception at 0x53349301 (nvopencl.dll) in OpenCLPracticeSetup.exe: 0xC0000005: Access violation reading location 0x656B5F5F.

我猜它是Visual Studio 2012的设置问题，但无法在线找到任何内容，因为nvopencl.dll没有看到错误这是我更改的属性
