11/19/08 SC08 ANL Booth Presentation What is Nimbus? l An extensible open source Infrastructure-as-a- Service implementation u Turns your cluster into a cloud l Why open source IaaS? u Experiment and use: make your own cloud or configure a private cloud u Customize: try new things, make the IaaS paradigm work for your application domain l Our particular interest in customization: scientific computing
11/19/08 SC08 ANL Booth Presentation Nimbus Features l Cloud computing infrastructure u WSRF and EC2 interfaces u Xen implementation (KVM in preparation for release) u Launches flexibly defined groups of VMs and configures their networking l Can be configured to use familiar schedulers like PBS and SGE to manage VMs u The workspace pilot l Launches self-configuring virtual clusters u The context broker l Defines an extensible architecture u And has been extended by various projects News Flash: Ian Gable from UVIC becomes a Nimbus committer!

11/19/08 SC08 ANL Booth Presentation CloudBLAST l CS research: investigate latency-sensitive apps, e.g. hadoop l Need access to distributed resources, and high level of privilege to run a ViNE router l Virtual workspace: ViNE router + application VMs l Paper: CloudBLAST: Combining MapReduce and Virtualization on Distributed Resources for Bioinformatics Applications by Andréa Matsunaga, Maurício Tsugawa and José Fortes, accepted to eScience 2008. U of Florida U of Chicago ViNE router ViNE router
11/19/08 SC08 ANL Booth Presentation STAR l STAR: a high-energy physics experiment l Needs resources with the right configuration u Complex environments: correct versions of operating systems, libraries, tools, etc all have to be installed. u Consistent environments: require validation l Solution: deploy a virtual OSG STAR cluster u OSG CE (headnode) plus STAR worker nodes: SL4 + STAR conf l Requirements u One-click virtual cluster deployment u Migration: Science Clouds -> EC2 l Last September: EC2 runs of up to 100 nodes (production scale, non-critical codes) l Testing for critical production deployment l Work by Jerome Lauret, Doug Olson, Leve Hajdu, Lidia Didenko
11/19/08 SC08 ANL Booth Presentation Infrastructure Testing l Project: tests of various Globus components on different platforms for correctness and scalability l Need short-term but flexible access to diverse platforms l Workspaces: Globus 101 + others l Work by various members of the Globus Toolkit (Tom Howe, John Bresnahan, Stu Martin, Martin Feller) l Resulted in provisioning a private Nimbus cloud for Globus
