PPT-Warp Scheduling Basics Loose Round Robin (LRR)

Goes around to every warp and issue if ready R If warp is not ready W skip and issue next ready warp Issue Warps all run at the same speed potentially all reaching memory access phase together and stalling. Let Me Count the Reasons…. Despite its widespread use, Round Robin reading has never been widely advocated nor endorsed by scholars of reading. For example, . Eldredge. , . Reutzel. , and Hollingsworth (1996) found that it was inferior to the shared book experience, another form of instructional book reading, in promoting word recognition, accuracy, fluency, vocabulary acquisition, and comprehension..

Given a set of clients with associated weights, a proportional share scheduler should allocate resources to each client in proportion to its respective weight..
