  1. Science Gateways to DEISAMotivation, user requirements, and prototype example Thomas Soddemann, RZG, Germany 14, Chicago, IL, 2005

  2. 14, Chicago, IL, 2005

  3. To deploy and operate a persistent, production quality, • distributed supercomputing environment with continental • scope • To enable scientific discovery across a broad spectrum of • science and technology. Scientific impact (enabling new • science) is the only criterion for success. 14, Chicago, IL, 2005

  4. DEISA is an European Supercomputing Service built on • top of existing national services. • DEISA deploys and operates a persistent, production • quality, distributed supercomputing environment with • continental scope 14, Chicago, IL, 2005

  5. DEISA Infrastructure • Dedicated 1GBit/s Network • Global File System (GPFS) • UNICORE centric Grid Middleware Infrastructure • PKI based security solution (EUGridPMA) 14, Chicago, IL, 2005

  6. Global File System RZG (GER) CINECA (I) First global file system worldwide in production environments at continental scope Global File System AIX SUPER-CLUSTER JUNE 2005 FZJ (GER) IDRIS (F) 14, Chicago, IL, 2005

  7. RZG (GER) GPFS demo at European Scale(June 16, 2005, Paris) CINECA (I) • A 256 processor job is running at RZG (Germany). The data for this run have been read from IDRIS (France), where hey have been produced by a former job (No ftp, transparent for the user as in a local cluster) Global File System 2) The application writes the restart data to the Jülich GPFS file system and result data to RZG FZJ (GER) IDRIS (F) • The results are interpreted and displayed in CINECA, reading the data from RZG (Germany) 14, Chicago, IL, 2005

  8. Ways of Access to Resources: CLI ssh, qsub/llsubmit, qstat/llq, … 14, Chicago, IL, 2005

  9. Ways of Access to Resources: Rich Client Solution 14, Chicago, IL, 2005

  10. Ways of Access to Resources: Web Portal Solution 14, Chicago, IL, 2005

  11. Ways of Access to Resources: Web Services 14, Chicago, IL, 2005

  12. Ways of Access to Resources: other • Globus2 • CORBA • WebDAV • … 14, Chicago, IL, 2005

  13. User Requirements • Easy access to computing resources • Simple access to computing resources • Hide the complexity of the Grid Infrastructure 14, Chicago, IL, 2005

  14. First Time Contact Obstacle: understanding PKI obtaining a certificate handling of certificate and private key Proxy Key, Proxy Certificate Certificate Authority GridPMA Obstacle: understanding the Grid Infrastructure Why does my job not run? Why does my job die? Where are my data? 14, Chicago, IL, 2005

  15. Unsophisticated and intuitively usable GUI • Let the user decide on the level of sophistication • E.g. use of known keywords • Help with the creation of input files for complex Applications • Wizards • Upload facilities, server side file browsing • Help the user to focus on science 14, Chicago, IL, 2005

  16. The Material Science and Fusion Portal Solution (Prototype) • Secure • PKI infrastructure for Authentication/Authorization • Extensible • Concept of pluggable modules in • UNICORE client and Portal prototype • Built on open standard and enterprise quality components • Tomcat/JBoss, Cocoon, org.apache.*, … • Separation of concerns • Design adheres to several widely accepted Patterns 14, Chicago, IL, 2005

  17. WAS EAS Client Application (Web Browser) UNICORE Controller MBean WebDAV MD EJB WAN Package LDAP Session EJB View Persistent Component DB Portal Application 14, Chicago, IL, 2005
