ILAB Layout Summary

• Designed to be broadly accessible for classes, projects, research

• All usable remotely

• Networked to leverage other local resources

Mackenzie ‘02 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

Mackenzie ‘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

Mackenzie ‘02 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

Mackenzie ‘02 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

Mackenzie ‘02 17

Summary of Regular Classes

• ILAB available as a resource to numerous classes, project venues

• EVBs, simulator in use since Spring ‘01

Mackenzie ‘02 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

Mackenzie ‘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/

Mackenzie ‘02 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

Mackenzie ‘02 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

Mackenzie ‘02 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!

Mackenzie ‘02 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

Mackenzie ‘02 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

Mackenzie ‘02 25

IXA Class Summary

• Project-driven using ILAB resources

• High Performance Communication– many aspects

• Expect to grow and to rotate among interested faculty

Mackenzie ‘02 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 ‘02Research project discussion in afternoon
