As Grid technologies evolve quickly on Internet, research related to resource scheduling faces new opportunities and challenges. These new technologies, ideas and approaches provide a new environment for researching and developing the economy-based resource scheduling system. Aiming at the hierarchical Grid model, following utility optimization thinking, while an universal flexible utility function...
Cloud computing is a natural evolution for data and compute centers with automated systems management, workload balancing, and virtualization technologies. Cloud-based services integrate globally distributed resources into seamless computing platforms. In an open cloud computing framework, scheduling tasks with guaranteeing QoS constrains presents a challenging technical problem. This paper presents...
Cloud computing focuses on delivery of reliable, fault-tolerant and scalable infrastructure for hosting Internet based application services. This paper presents the implementation of an efficient Quality of Service (QoS) based Meta-Scheduler and Backfill strategy based light weight Virtual Machine Scheduler for dispatching jobs. The user centric meta-scheduler deals with selection of proper resources...
Aggregation of flows into classes is used to avoid the scalability problems of IntServ model and this requires per-class scheduling decisions. There are number of issues associated with such approach e.g. what will be per-flow guarantee, which flows are to be aggregated together, how to determine service order among multiple classes and within a class etc. DiffServ model is a framework wherein class...
