CUDAを使って“Hello World!!”
Hello World!! を表示するサンプル(main.cu)
__global__ void hello( char *data )
{
char *text = "Hello World!!¥n";
data[ threadIdx.x ] = text[ threadIdx.x ];
}
int main( int argc, char *argv[] )
{
char *dData, hData[ 15 ];
}
cudaMalloc( ( void ** )&dData, sizeof( char ) * 15 );
dim3 nThreads( 15, 1 );
dim3 nBlocks( 1, 1 );
hello>( dData );
cudaMemcpy( hData, dData, sizeof( char ) * 15, cudaMemcpyDeviceToHost );
printf( "%s", hData );
cudaFree( dData );
return( 0 );
