GSvit does not support use of all of them at once, but you can still run up to four different instances on different cards.

GSvit does not support use of all of them at once, but you can still run up to four different instances on different cards. The basic settings for using the GPU are therefore whether to use it at all (GPU directive in the parameter file) and eventually which one to use (UGPU directive in the parameter file). GPUs are numbered from 0, exactly the same way as what <tt>gsvit test 0</tt> outputs, so these settings in the parameter file: |
