写入位置时发生访问冲突。自己写了个函数用来读取device中的数据至OMEGA中 调用时报错

Question

 OMEGA=ReadtoOMEGA(temp_data,OMEGA,width,num_pixels,bands,e1,count_Duanyuan);

 float * ReadtoOMEGA(void const * const device,float * OMEGA,size_t const width,size_t const num_pixels,size_t const bands,int e,int count)
{
    int i=0,posOmega=0,posData=0;
    float *ptr=(float *)device;
    float *ptr_OMEGA=(float *)OMEGA;
#pragma unroll
    for (i=0;i<bands;i++)
    {
        posOmega=i+count*bands;
        posData=e+i*num_pixels;
        ptr_OMEGA[posOmega]=ptr[posData];
    }
    //float *OMEGA_temp=(float *)ptr_OMEGA;
    //OMEGA=OMEGA_temp;
    return ptr_OMEGA;
}

Answer 1

没有错误信息，恐怕不太好看。
