12. ILAB Layout Summary • Designed to be broadly accessible for classes, projects, research • All usable remotely • Networked to leverage other local resources

13. Outline • ILAB layout • designed to be broadly accessible • ILAB as class project resource • in use (simulation & EVBs) since Spring ‘01 • High Performance Communication class • IXA-based class, Spring ‘02

14. Class Projects • ILAB available for class projects and senior projects in non IXA-specific ECE/CoC classes • Classes: • Networking (regular class, lab class) • Systems (OS, architecture, realtime, embedded) • Projects: • ECE “capstone” design projects • CS senior group projects • Undergraduate research projects

15. Class Projects to Datewarmup material for IXA class in Spring ‘02! • CS6235 realtime/embedded (Spring ‘01) • two realtime scheduler projects • CS4903 undergraduate research (Spring ‘01) • evaluation of transforming memcpy • CS7001 intro to grad school (Fall ‘01) • mini-project on image downsampling • CS6290 computer architecture (Fall ‘01) • TCP splicing • alternate SYN handshake protocol

16. Future Classes • Systems: OS, architecture, realtime • already integrated • Networking (CS and ECE) • expect to start this summer • Senior Projects, Undergrad Research • partly underway; grows naturally

17. Summary of Regular Classes • ILAB available as a resource to numerous classes, project venues • EVBs, simulator in use since Spring ‘01

18. Outline • ILAB layout • designed to be broadly accessible • ILAB as class project resource • in use (simulation & EVBs) since Spring ‘01 • High Performance Communication class • IXA-based class, Spring ‘02

19. CS8803J: High Performance Communication • Class oriented around IXA-based lab work • Topic is Communication: internet/cluster, networking/network interfaces/software • Format is project-driven. Class time is largely paper discussions with some lectures • First cut Spring ‘02: • http://www.cc.gatech.edu/classes/AY2002/cs8803j_spring/

20. Projectsthree canned; final is open • Project 1: transmitter/receiver code (3 weeks) • in assembly (eventually C) • goal: absorb all relevant documentation • Project 2: ACEs (2 weeks) • tutorial plus an extension, e.g. integrate a stack ACE • goal: tool workflow, debugging workflow • Project 3: PCI communication (2 weeks) • evaluate PIO, DMA performance betw. IXP and host • goal: evaluation methodology

21. Reading • IXP and NP-specific • documentation, recent IXP papers, microproc. report • Internetworking issues • TCP basics, current issues • Network interface issues • “active” vs. sender-controlled; case studies • Software issues • messaging models, scheduling

22. Spring ‘02 Edition • 11 students + 3 listeners • 2 undergrads, 2 ECE, rest from CoC • 2 networking, 4 architecture, rest from systems • Much group debugging • debugging ILAB setup, sample code, projects • Prj1/2 took longer than expected; punted #3 • Book looks invaluable • and follows much the same approach!

23. Sample Final Projects • Networking • fused links • Infosec • IDS system component; standalone IDS functions • Network Interface • IXP as standard ethernet adapter • volume transport across PCI bus • Multimedia • packet scheduling

24. Future Plans • Teach yearly in Spring • Rotate among interested faculty • e.g. expect more networking slant with networking faculty • Expect to grow given large potential audience

25. IXA Class Summary • Project-driven using ILAB resources • High Performance Communication • many aspects • Expect to grow and to rotate among interested faculty

26. ILAB Education Summary • ILAB layout • designed to be broadly, remotely accessible • ILAB as class project resource • in use (simulation & EVBs) since Spring ‘01 • High Performance Communication class • IXA-based class, Spring ‘02 Research project discussion in afternoon
