  1. ULabGrid, an infrastructure to develop distant laboratories for undergraduate students over a Grid O.Ardiaz, D.Royo et al. Dept. of Computer Architecture Polytechnic University of Catalonia, Spain

  2. Outline • Introduction • Advantages of using ULabGrid • Implementation • Architecture • Functionality • Conclusions and future work plans

  3. Introduction • Virtual laboratories • Ease overcrowding • Access from anywhere • Provide operating system services for networked resources • Facilitate necesarry tools • On-line manuals, FAQs, examples etc.

  4. Advantages of using ULabGrid • Dedicated software installation and maintenance • Reduces licensing problems • Extended hardware resource availability • Ease of changing lab content • Simplified user interfaces

  5. Implementation • Uses: • Globus (2.2) • GPDK (Globus Portal Development Kit) • VNC (Virtual Network Computing) • Main components • Session scheduler • Resource manager

  7. Functionality • Users connect via a browser to portal and choose tool to run, files needed etc. • Session Scheduler queries the Resource Manager for optimal machine and transfers needed files (GSIFTP) to it • VNCserver process at remote machine started and tool executes, VNC parameters sent to user • VNCviewer started by user • When done, Session Scheduler does cleanup

  8. GPDK Architecture

  9. Administrator interface

  10. Conclusions and future work plans • Propose looking into: • Process migration due to node failure • Resource mapping algorithms • System dynamics – notification services • Collaboration, working in groups
