Harnessing Virtual Machine Resource Control for Job Management

چکیده
Virtual machine technology promises important benefits for grid computing and cluster batch job systems, including improved isolation, customizable workspaces, and support for checkpointing and migration. One way to gain these benefits is to “drill holes” in existing batch computing systems; however, we believe these new capabilities warrant a rethinking of the architectures of existing systems. We propose separating resource control for VMs into a new foundational layer that focuses narrowly on resource management. We present JAWS, a new batch computing service that is built as a thin-layer above a resource control plane that enables it to share a common pool of networked cluster resources with other cluster services. JAWS executes jobs within isolated virtual machine workspaces. We discuss how exposing resource control allows JAWS to leverage VM-based resource isolation as a means to learn models of application behavior, and use those models to guide scheduling policies for efficient resource

Comparative Study of Job Migration Algorithms for Autonomic Grid Management
Resources form the basis of a Grid. Resource management and load balancing are the main areas of concern in a distributed, heterogeneous and dynamic environment like Grid. Load balancing may further cause Job migration or in some cases re-submission of Job. In this paper a number of job migration algorithms have been surveyed and studied which have resulted because of the Load balancing problem...

متن کاملVirtual manufacturing cells scheduling considering lotstreaming and sequence dependent setup times
In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufacturing cells, each job has a different processing path and there is a set of machines for processing each operation. The...
متن کاملO'Camelot: adding objects to a resource-aware functional language
We outline an object-oriented extension to Camelot, a functional language in the ML family designed for resource aware computation. Camelot is compiled for the Java Virtual Machine, and our extension allows Camelot programs to interact easily with the Java object system, harnessing the power of Java libraries and allowing Java programs to incorporate resource-bounded Camelot code.2
