Class Projects to Date • 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 Mackenzie ‘02 15 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 Mackenzie ‘02 16 Summary of Regular Classes • ILAB available as a resource to numerous classes, project venues • EVBs, simulator in use since Spring „01 Mackenzie ‘02 17 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 Mackenzie ‘02 18 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/ Mackenzie ‘02 19 three canned; final is open Projects • 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 Mackenzie ‘02 20 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 Mackenzie ‘02 21 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! Mackenzie ‘02 22 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 Mackenzie ‘02 23 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 Mackenzie ‘02 24 IXA Class Summary • Project-driven using ILAB resources • High Performance Communication – many aspects • Expect to grow and to rotate among interested faculty Mackenzie ‘02 25 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 Mackenzie ‘02 26
