The authors discuss the design and implementation of a parallel GUI Service in Tessellation OS and investigate its capability to provide soft service-time guarantees to visual applications. Use of GPU bandwidth reservation permits their GUI service to miss only 0.1% of client deadlines under an overloaded scenario, while a more traditional windowing system misses over 50% of its deadlines. Further, the GUI Service's parallel architecture nicely exploits parallelism to reduce service times for client requests.
