Hi, I was trying to text the non_blocking writing in function clEnqueueWriteBuffer. However the time I got is the same for CL_TRUE and CL_FALSE.
I thought CL_FALSE is for non_block writing, and should return immediately. The mem_init_time I got is about 9 seconds in my test for both CL_TRUE and CL_FALSE. Can someone tell me how to do the non_block writing? Thanks!
t_start = rtclock();
errcode |= clEnqueueWriteBuffer(clCommandQue, cl_k_matrix, CL_TRUE, 0, sizeof(double)*n_node1*n_node1, temp, 0, NULL, NULL);
errcode |= clEnqueueWriteBuffer(clCommandQue, cl_vertex, CL_TRUE, 0, sizeof(double)*n_node1*n_node2, temp1, 0, NULL, NULL);
errcode |= clEnqueueWriteBuffer(clCommandQue, cl_edge, CL_TRUE, 0, sizeof(double)*n_edge1*n_edge2, temp2, 0, NULL, NULL);
if(errcode != CL_SUCCESS){printf("Error in initializing buffers %d\n",errcode); exit(-1);}
t_end = rtclock();
mem_init_time=t_end-t_start;
