Time slicing

A GPU comprising:

• a microprocessor configured to schedule a plurality of active GPU drivers in a GPU, each of the active GPU drivers having an initial priority level, by:
• for one or more of the plurality of active GPU drivers, allocating a portion of a scheduling interval to the active GPU driver;
• selecting an active GPU driver for execution according to a priority-based scheduling algorithm;
• in response to an active GPU driver executing within its allocated portion, increasing the priority level of the active GPU driver;
• in response to the active GPU driver completing its workload within its allocated portion, resetting the priority level of the active GPU driver;
• in response to the active GPU driver executing for its whole allocated portion, reducing the priority level of the active GPU driver;
• and
• resetting the priority levels of each active GPU driver to their initial priority levels at the start of each scheduling interval.

A non-transitory computer readable storage medium having stored thereon computer readable code configured to cause a method of scheduling a plurality of active GPU drivers in a GPU to be performed when the code is run, each of the active GPU drivers having an initial priority level, the method comprising:

• for one or more of the plurality of active GPU drivers, allocating a portion of a scheduling interval to the active GPU driver;
• selecting an active GPU driver for execution according to a priority-based scheduling algorithm;
• in response to an active GPU driver executing within its allocated portion, increasing the priority level of the active GPU driver;
• in response to the active GPU driver completing its workload within its allocated portion, resetting the priority level of the active GPU driver;
• in response to the active GPU driver executing for its whole allocated portion, reducing the priority level of the active GPU driver;
• and
• resetting the priority levels of each active GPU driver to their initial priority levels at the start of each scheduling interval.
