Optimizing Grid Site Manager Performance With Virtual Machines

Overview 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. This paper considers 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. The 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.

Virtualisation gets trendy

Grid computing is also an example of resource aggregation, as it enables the virtualisation of distributed IT resources such as storage, bandwidth and CPU cycles, while splitting a mainframe into logical partitions is an example of partitioning.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
