    Update: find the slides from the talk here.

    Computing Techniques Seminar

    Thursday, January 29, 2pm. Feynman Computing Center, Fermilab.

    Abstract:

    Infrastructure-as-a-Service (IaaS) cloud computing is emerging as a viable alternative to the acquisition and management of physical resources. But what exactly is cloud computing and to what extent can it be used to meet the needs of scientific applications?

    In this talk, I will give an overview of cloud computing and describe Nimbus -- a toolkit that provides an open source, EC2-compatible IaaS implementation as well as tools that enable, for example, the creation of tightly-coupled clusters such as are often used in science.

    I will describe how applications drove the development of various Nimbus capabilities and how they use these capabilities today on Amazon EC2 and the Science Clouds. Finally, I will discuss the emerging trends in cloud computing and discuss how they can benefit science.

  • Virtual Workspaces Tutorial at Open Source Grid Cluster (May 12-16, 2008) (#)

    There will be a Virtual Workspaces tutorial at the Open Source Grid Cluster conference in Oakland, CA. The conference is May 12-16, 2008. The Virtualization and Cloud Computing with Globus session is on Wednesday, May 14th, from 4:30-6:00 pm. We hope to see you there!

    Quoting from the summary:

    One of the primary obstacles users face in grid computing is that Grids provide access to many diverse resources, their applications often require a very specific, customized environment. This disconnect can lead to resource underutilization, user frustration, and much wasted effort spent on bridging the gap between applications and resources. Virtual Workspaces describe the environment required for the execution of an application that can be dynamically deployed across a variety of resources creating a working and consistent platform for grid applications.

    This tutorial will introduce the Globus Toolkit workspace service that implements workspaces as Xen virtual machines and enables authorized grid clients to dynamically deploy them and manage their resources. Further, we will describe and demonstrate the workspace "cloudkit" that provides a user-friendly interface on top of the workspace service allowing authorized users to easily provision and run VMs on the available community clouds. Finally, we will describe how the process of contextualization can be used to provide on-demand functioning clusters and give examples of its use by applications.
