The code:
float *h_A0;
float *h_Anext;
size=nx*ny*nz;
printf("2\n");
h_A0=(float*)malloc(sizeof(float)*size);
h_Anext=(float*)malloc(sizeof(float)*size);
FILE *fp = fopen(parameters->inpFiles[0], "rb");
read_data(h_A0, nx,ny,nz,fp);
fclose(fp);
printf("3\n");
memcpy (h_Anext,h_A0 ,sizeof(float)*size);
printf("4\n");
Please help
Thank you in advance
