When you use GPU on CST, you must use Quadro graphic card. You cannot use another graphic card. For details, please visit Nividia Tesla page.
When CST use GPU, CST firstly prepare database to GPU. Then GPU solve this database accordingly. So, if your problem is small, the time for CPU to prepare database for GPU will be dominated. Not much gain of GPU will be found. If your problem is very big, the CPU may spend more time to prepare database for GPU. Therefore, you should have a very powerfull CPU if you are going to solve a big problem. |
