1. WNoDeS – Worker Nodes on Demand Service on EMI2 WNoDeS – Worker Nodes on Demand Service on EMI2 Local batch jobs can be run on both real and virtual execution hosts. (Worker Nodes) A virtual Worker Node is instantiated on-demand to provide computing resources for the execution of batch jobs just when needed. WNoDeS allows customized execution environments based on VMs, built and instantiated to match user requirements. Deployment WNoDeS is in production at the INFN Tier-1 Computing Center (Bologna – Italy), fully integrated with its 9000-cores farm. 2000 VMs can currently be instantiated on-demand out of this common farm to support Cloud computing, or custom executing environments. WNoDeS is also installed at two INFN Tier-2 centers (Bari and LNL). Grid/Cloud Full Integration Support for multiple batch systems (Platform LSF, PBS/Torque) Authentication Gateway VM image selection VirtIO support Network throttling WNoDeS VIP: on-demand provisioning of virtual user interfaces for local users out of a common resource pool. Based on a CLI, it can be easily used by computing center users seeking for additional, unused resources. Provides customized computing resources for interactive usage. (for example, software development or physics analysis) The provisioned virtual resource matches user requirements for RAM, CPU, bandwidth and shared file systems to be mounted. A caching mechanism is available, to reduce system provisioning time.

Resource selection is based on a Glue 1.x schema attribute (SoftwareRunTimeEnvironment) This interoperates with current gLite WMS and CREAM CE middleware. Authentication is based on VOMS (Virtual Organization Membership Service). Authorization is based on the EMI (European Middleware Initiative) ARGUS Authorization Service. WNoDeS has a Cloud Computing interface based on the OCCI API. This API is either accessible programmatically for maximum flexibility, or via a Web-based Application for maximum ease of use. This provides on-demand computing resources allocated to users out of a common pool. Authentication is internally based on Short-Lived X.509 Certificates obtained through an online CA. Through a general resource access portal being developed in collaboration with the Italian Grid Infrastructure (IGI), users can authenticate through several methods, like Kerberos, Shibboleth, X.509/VOMS or Username/Password.
