  1. National Energy Research Scientific Computing Center (NERSC) Visportal : interface to grid enabled NERC resources Cristina Siegerist NERSC Center Division, LBNL June 24th, 2004

  2. Visportal Project • The LBNL/NERSC VisPortal effort explores ways to deliver Grid-based advanced visualization and data analysis capabilities through a Web Portal interface. • Using standard Globus Grid middleware and off the shelf web automation, the VisPortal hides the underlying complexity of resource selection and distributed application management.

  3. Web Server Tomcat Job Submission GPDK Portal Engine (Servlets) Application Logic Presentation (JSP) Information Services Data Transfer Grid Service Beans User Profiles Grid Middleware Libraries Security (e.g. CoG) globus Visportal Project Internal Architecture

  4. Visportal Project • VisPortal Services: • Motivation: simplify remote visualization, offer point an click solutions for complex distributed applications • File Management • One button Mpeg • … (User’s grid workflows?)

  5. Visportal Project User’s perspective • Accounts in all the resources. • Request a user certificate: http://www.doegrids.org/pages/cert-request.html • Be in the grid-map files of the resources (automated through NIM). • Create a proxy certificate and login. Delegate it to myproxy.nersc.gov

  6. Visportal Project Login Page • Myproxy: username and password of delegated credential • Local: load from credential file (grid-proxy-init)

  7. Visportal Project Profile • Update user’sresourcesjob historyemail address

  8. Visportal Project File Mgmt. • Foreground transfers • Background transfers • Globus File Yanker(Shreyas Cholia)
