The present study, which is about practical methods of improving productivity in Mashhad ring factory, is presented in five chapters. In the foreword, the need for an attitude to improve productivity at the national level as well as in industry has been mentioned and has laid the groundwork for starting a discussion of productivity and practical solutions to improve it. In the first chapter, by defining productivity, considers the different perceptions of societies about productivity and finally deals with misconceptions about the concept of productivity. In the second chapter, based on committed articles from the American Society of Industrial Engineering, discusses the role of industrial... 

GPUs exploit memory hierarchy and thread-level parallelism (TLP) to hide off-chip memory access delay. However, GPUs can not keep TLP high during the execution of various applications, and hence, they fall short of hiding the access delay to off-chip memory. One effective approach to reducing memory access delay is prefetching. Prior research shows the positive impact of prefetching in improving the performance of GPUs. However, they fail to capture all the potential behind the prefetching in GPUs. In this thesis, we propose Snake, a new data prefetching in GPUs. Snake identifies stride distances among different memory access instructions and prefetches a chain of addresses that will be...
