o Individual GPU program launches are limited to a run time
of less than 5 seconds on a GPU with a display attached.
Exceeding this time limit usually causes a launch failure
reported through the CUDA driver or the CUDA runtime. GPUs
without a display attached are not subject to the 5 second
runtime restriction. For this reason it is recommended that
CUDA be run on a GPU that is NOT attached to a display and
does not have the Windows desktop extended onto it. In this
case, the system must contain at least one NVIDIA GPU that
serves as the primary graphics adapter.
