Optimizing Grid Site Manager Performance with Virtual Machines

Virtualization can enhance the functionality and ease the management of current and future Grids by enabling on-demand creation of services and virtual clusters with customized environments, QoS provisioning and policy-based resource allocation.

In this work, we consider the use of virtual machines (VMs) in a data-center environment, where a significant portion of resources from a shared pool are dedicated to Grid job processing. The goal is to improve efficiency while supporting a variety of different workloads.

We analyze workload data for the past year from a Tier-2 Resource Center at the RRC Kurchatov Institute (Moscow, Russia). Our analysis reveals that a large fraction of Grid jobs have low CPU utilization, which suggests that using virtual machines to isolate execution of different Grid jobs on the shared hardware might be beneficial for optimizing the data-center resource usage. The introduction of VMs for Grid job execution enables policy-based resource allocation and management in the data center: the administrator can dynamically change the number of physical nodes allocated for Grid jobs versus enterprise applications without degrading performance support for Grid processing. Live migration of VMs makes the management process even more flexible.
