  1. Grid Infrastructure group (Charlotte): Barry Wilkinson Jeremy Villalobos Nikul Suthar Keyur Sheth Department of Computer Science UNC-CharlotteMarch 16, 2006 VisualGrid project meeting Portal Development

  2. Goals of Infrastructure Group • To develop grid infrastructure • Provide technical direction to enable UNC-C, UNC-A, and EPA sites to interconnect as grid, working with grid infrastructure members at other sites. • Develop a user interface so that users can submit jobs to any site. • Customize interface to satisfy user requirements • …

  3. Computing Resources at Charlotte • For initial development: • CS dept. 4-node dual 3.4 GHz Xeon server • Called coit-grid01.uncc.edu – coit-grid04.uncc.edu • Initially purchased from a grant for Fall 2005 grid computing course • Planned UNC-C resources to add: • University research 51-node dual Xeon cluster • Chuck Price and Mike Mosley • Bioinformatics cluster 41-node and 8-node G5 clusters • Larry Mays and John Merritt

  4. Software • Globus 4.0.x – provides very basic grid components • OGCE2/Gridsphere portal • User interface • SimpleCA – certificate authority • Globus PKI Security • Complete VisualGrid will have multiple certificate authorities with cross certification • Local Job Schedulers • Sun Grid Engine and Condor

  5. X509 Certificates • X509 certificates are used to provide security in a grid system. • Each user needs a certificate issued by a “certificate authority” (CA). • Grid systems use a so-called user proxy certificates to allow resources to control resources on the user’s behalf.

  6. UNC-C CA Users certified by a local CA

  7. UNC-C UNC-A CA CA CA’s with Mutual Trust GT4

  8. EPA UNC-A UNC-C CA CA CA Final VisualGrid infrastructure

  9. Multiple Grid Nodes With multiple grid nodes, users need: • Account on each system, and access control set accordingly. • A certificate acceptable by the local certificate authority (i.e. signed by a CA it trusts)

  10. Getting an account Web-based VisualGrid form Fill in form New User CA/System Administrator Initial username and password Create accounts, set access control, sign certificate, …

  11. CA CA Experimental configuration at UNC-C VisualGrid portal URL: http://coit-grid01.uncc.edu:8080/gridsphere (Portals on other systems for experimentation.) coit-grid02 coit-grid01 Certificate authorities (SimpleCA) coit-grid03 All with Globus 4.0 Sun Grid Engine scheduler on grid01-grid02 Condor on Grid 03-grid04 coit-grid04

  12. VisualGridPortal Based upon OGCE2/Gridsphere Provides: User login Proxy certificate generation Job submission to any enrolled system Secure file transfers Informational tools

  13. Portal login page (OGCE2/gridsphere portal)

  14. Usual portlets:

  15. Proxy Manager

  16. Job Submission

  17. File Transfer
