Research ArticleOpen accessEvery word in the titleMULTI-LEVEL PRIORITY-BASED SCHEDULING MODEL IN HETEROGENEOUS CLOUDSiti Fajar Jalal, Masnida HussinCloud has emerged into another enhancement that manipulates the diversity of resources in order to expand the ability of Cloud facility. Cloud is no longer being seen as one-type service provider. The advantages of the heterogeneous Cloud give great benefits to the users and have business potential in service market. To cope with the dynamic nature of heterogeneous Cloud, the … …Journal of Computer Science, Vol. 10, Issue 12 · 5 Jan 2015 · 7,970 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRESOURCE BROKER MANAGEMENT BY ADOPTING SELF-ADAPTIVE MULTI-INSTANCE BROKER SCHEDULING IN GRID COMPUTINGBakri Yahaya, Rohaya Latip, Azizol Abdullah, Mohamed OthmanA grid resource broker seeks to assign the appropriate jobs to the appropriate resources as part of resource management in the multi-grid environment. Multi instances of the broker system provides multiple instances of brokers to simultaneously process jobs between multiple resources in a hierarchical cluster grid environment. In this study, the multi-instance broker is developed using grid resource broker taxonomy … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 8,879 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRTOS IMPLEMENTATION OF NON-LINEAR SYSTEM USING MULTI TASKING, SCHEDULING AND CRITICAL SECTIONM. Sujitha, V. Kannan, S. RaviRTOS based embedded systems are designed with priority based multiple tasks. Inter task communication and data corruptions are major constraints in multi-tasking RTOS system. This study we describe about the solution for these issues with an example Real-time Liquid level control system. Message queue and Mail box are used to perform inter task communication to improve the task execution time … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,104 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDYNAMIC MODELING AND GAIN SCHEDULING CONTROL OF A CHIILLED WATER COOLING SYSTEMJun Liu, M. ZaheeruddinA dynamic model of a Chilled Water (ChW) cooling system with a stratified ChW tank was developed. A PI-based Gain Scheduling (GS) control strategy was designed to improve thermal performance of the chiller system. Five different operation strategies were simulated and the energy consumption and cost of operating the system under full load and partial load conditions were compared. The … …Energy Research Journal, Vol. 5, Issue 1 · 15 Oct 2014 · 7,015 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCASE STUDY OF THE OPTIMIZING THE AUTOMOTIVE MANUFACTURING SYSTEMS EFFICIENCY VIA APPLYING NEW METHOD OF SCHEDULINGSeyedehfarzaneh Nojabaei, Matthew FranchettiEfficiency is becoming a pivotal aspect in each manufacturing system and scheduling plays a crucial role in sustaining it. The applicability of distributed computing to coordinate and execute jobs has been investigated in the past literature. Moreover, it is significant that even for sensitive industrial systems the only criterion of allocating jobs to appropriate machines is the FIFO policy. On … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 2 · 8 Jul 2014 · 7,426 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA COMBINED LOW LATENCY AND WEIGHTED FAIR QUEUING BASED SCHEDULING OF AN INPUT-QUEUED SWITCHK. Bommanna Raja, D. RaghupathikumarInput queuing has become dominant and popular building blocks for high speed crossbar switches with many ports and fast line rates because they require minimum speed-up of memory bandwidth. Input Queued switches with finite Virtual Output Queues guarantees QoS performance in terms of throughput and average delay. A switch performs two functions Queuing and Scheduling. Queue Management algorithm manages the … …Journal of Computer Science, Vol. 10, Issue 8 · 25 Mar 2014 · 7,232 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NEW-THRESHOLD BASED JOB SCHEDULING FOR GRID SYSTEML. RamaparvathyIn heterogeneous distributed systems, utility grids have emerged as a new model of service. In this service, workflow scheduling is one of the challenging problems for satisfying user’s quality requirements. One of the main issues in work flow scheduling is to minimize the workflow execution cost in terms of time and makespan. In this study, we propose a new workflow … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,792 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQUANTITATIVE EVALUATION OF JOB AND RESOURCES FOR BETTER SELECTION TO IMPROVE MAKESPAN IN GRID SCHEDULINGKrishnamoorthy Natarajan, Asokan Ramasamy, Sangeetha SubramanianThis study presents the Priority based ranking of jobs and resources to improve the Makespan in the grid scheduling problem. Grid environment’s effectiveness largely depends on scheduler’s effectiveness/efficiency as they act as local resource brokers. The scheduler is responsible to select resources/scheduling jobs so that users/application requirements are met regarding overall execution time (throughput) and the resources use cost. The … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,558 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIMPROVING FAULT TOLERANT RESOURCE OPTIMIZED AWARE JOB SCHEDULING FOR GRID COMPUTINGK. Nirmala Devi, A. TamilarasiWorkflow brokers of existing Grid Scheduling Systems are lack of cooperation mechanism which causes inefficient schedules of application distributed resources and it also worsens the utilization of various resources including network bandwidth and computational cycles. Furthermore considering the literature, all of these existing brokering systems primarily evolved around models of centralized hierarchical or client/server. In such models, vital responsibility such … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,904 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAPPLICATION OF A FUZZY-SIMULATION MODEL OF SCHEDULING ROBOTIC FLEXIBLE ASSEMBLY CELLSKhalid Abd, Kazem Abhary, Romeo MarianThis study describes the application of the developed model to the scheduling of the Robotic Flexible Assembly Cells (RFACs). The present study is a continuation of the paper titled “Development of a Fuzzy-Simulation Model of Scheduling Robotic Flexible Assembly Cells”.
