1 Open Science Grid Living on the Edge: OSG Edge Services Framework Kate Keahey Abhishek Rana

2 SC05 booth presentation OSG Edge Services Framework 2 Open Science Grid Edge Services Services executing on the edge of the public and private network Site CDF CMS ATLAS Guest VO SE CE Compute nodes and Storage nodes

3 SC05 booth presentation OSG Edge Services Framework 3 Open Science Grid Edge Service Requirements Configuration Issues –The configuration requirements can vary widely per Edge Service per community. –We need an easy way to upgrade Edge Services –Alternative Edge Services Resource allocation issues –Flexibility in dynamically managing resource assignments as load demands fluctuate –Fair usage between communities –Incentives

4 SC05 booth presentation OSG Edge Services Framework 4 Open Science Grid Virtual Machines Excellent isolation, security, fine-grain forensics… Promising enforcement properties More control to the site & great recoverability Flexible configuration The ability to serialize and migrate Modern implementation are fast LXVU SPEC INT2000 (score) LXVU Linux build time (s) LXVU OSDB-OLTP (tup/s) LXVU SPEC WEB99 (score) Benchmark suite running on Linux (L), Xen (X), VMware Workstation (V), and UML (U)

5 SC05 booth presentation OSG Edge Services Framework 5 Open Science Grid Virtual Workspaces Virtual Workspaces: environments that can be made available dynamically on the Grid –Different possible implementations Workspace Service –Enables secure deployment and management of a workspace within a trusted computing base Authentication and authorization Deployment configuration Resource allocation enforcement –Workspace = deployment meta-data + image –More information and technology preview download available at

18 SC05 booth presentation OSG Edge Services Framework 18 Open Science Grid ESF Project Phase 1 objective: create a proof-of-concept dynamic deployment of Edge Services Progress: Implement and release the Workspace Service Bubbly test: static deployment and test of a real Edge Service on a production site Dynamic deployment of an Edge Service and integration into OSG infrastructure Configuring more testbeds Deploying and testing more Edge Services

19 SC05 booth presentation OSG Edge Services Framework 19 Open Science Grid Testbed & Images Testbed –SDSC (Abhishek) OSG production site, 150+ worker nodes Intel 2.6, 4GB, RAID device, Xen –FNAL (Burt) Xeon 3.2, 4GB, RAID device, Xen –UC (Rob, Borja) TeraPort, Xen 3 –ANL, PIOCON coming online Images –SDSC: SL3.0.3, FC4, CentOS4.1 –FNAL: SL3.0.3, SL4, LTS 3, LTS 4 Edge Services –ATLAS: mysql-gsi db built by the DASH project

20 SC05 booth presentation OSG Edge Services Framework 20 Open Science Grid Summary Growing ESF testbed –Xen capabilities / ESF requirements –Installation woes getting worked out Growing library of images with useful configurations Growing infrastructure
