about cuda support or nvcc support. maybe it can be describe better,I do not how to say in detail

I have a problem! when I use this plugin to execute the code with cuda,it failed!

include

include "cublas_v2.h"

define M 6

define N 5

define IDX2F(i,j,ld) ((((j)-1)*(ld))+((i)-1))

void modify (cublasHandle_t handle, float *m, int ldm, int n, int p, int q, float alpha, float beta){ cublasSscal (handle, n-q+1, &alpha, &m[IDX2F(p,q,ldm)], ldm); cublasSscal (handle, ldm-p+1, &beta, &m[IDX2F(p,q,ldm)], 1); }

int main (void){ cudaError_t cudaStat; cublasStatus_t stat; cublasHandle_t handle; int i, j; float devPtrA; float a = 0; a = (float )malloc (M N sizeof (a)); if (!a) { printf ("host memory allocation failed"); return EXIT_FAILURE; } for (j = 1; j <= N; j++) { for (i = 1; i <= M; i++) { a[IDX2F(i,j,M)] = (float)((i-1) * N + j); } } cudaStat = cudaMalloc ((void*)&devPtrA, MNsizeof(a)); if (cudaStat != cudaSuccess) { printf ("device memory allocation failed"); return EXIT_FAILURE; } stat = cublasCreate(&handle); if (stat != CUBLAS_STATUS_SUCCESS) { printf ("CUBLAS initialization failed\n"); return EXIT_FAILURE; } stat = cublasSetMatrix (M, N, sizeof(a), a, M, devPtrA, M); if (stat != CUBLAS_STATUS_SUCCESS) { printf ("data download failed"); cudaFree (devPtrA); cublasDestroy(handle); return EXIT_FAILURE; } modify (handle, devPtrA, M, N, 2, 3, 16.0f, 12.0f); stat = cublasGetMatrix (M, N, sizeof(a), devPtrA, M, a, M); if (stat != CUBLAS_STATUS_SUCCESS) { printf ("data upload failed"); cudaFree (devPtrA); cublasDestroy(handle); return EXIT_FAILURE; } cudaFree (devPtrA); cublasDestroy(handle); for (j = 1; j <= N; j++) { for (i = 1; i <= M; i++) { printf ("%7.0f", a[IDX2F(i,j,M)]); } printf ("\n"); } free(a); return EXIT_SUCCESS; }

how can I change it？

You need to load the library, see Using third-party libraries

It doesn't work
