Actually on CPU thread that made yiu hate me, i like your comment. I asked about when can CPU be used was not antagonism but you read it that way. But yes, you r right, im not estabkished. For ur info, Im a phD student too at age 38 hahaha. But also a share holder on private property company, and a owner of a small apartment. Im no shy that I am still fighting for signal/image detection phD at this age. haaha
