我有這樣的代碼在CUDA與C++:參數類型的「無符號整型*」是與類型的參數不兼容的「爲size_t *」
// Variables
float *query_dev;
float *ref_dev;
float *dist_dev;
int *ind_dev;
cudaArray *ref_array;
cudaError_t result;
size_t query_pitch;
size_t query_pitch_in_bytes;
size_t ref_pitch;
size_t ref_pitch_in_bytes;
size_t ind_pitch;
size_t ind_pitch_in_bytes;
size_t max_nb_query_traited;
size_t actual_nb_query_width;
unsigned int memory_total;
unsigned int memory_free;
// Check if we can use texture memory for reference points
unsigned int use_texture = (ref_width*size_of_float<=MAX_TEXTURE_WIDTH_IN_BYTES && height*size_of_float<=MAX_TEXTURE_HEIGHT_IN_BYTES);
// CUDA Initialisation
cuInit(0);
// Check free memory using driver API ; only (MAX_PART_OF_FREE_MEMORY_USED*100)% of memory will be used
CUcontext cuContext;
CUdevice cuDevice=0;
cuCtxCreate(&cuContext, 0, cuDevice);
cuMemGetInfo(&memory_free, &memory_total);
我得到一個錯誤爲在該行編譯:cuMemGetInfo(& memory_free,& memory_total);
的錯誤是:
app.cu(311): error: argument of type "unsigned int *" is incompatible with parameter of type "size_t *"
app.cu(311): error: argument of type "unsigned int *" is incompatible with parameter of type "size_t
311線:cuMemGetInfo(&memory_free, &memory_total);
我不知道這是什麼錯誤,你對此有任何想法?
是的,它的工作原理。謝謝! – olidev
當然,很高興幫助:) –
