CS/EE6760 Fall 1998 Project 1: Cache Design

• dates: out 2-Oct-98, due 15-Oct-98.
• handout: project1.ps, project1.pdf (XXX -- equations scrambled in the .pdf !?)
• appendix: cachesim5.ps, cachesim5.pdf
• simulator and benchmarks: /users/projects/class/6760/fall98/

• My intention is to give an official AMAT to all the designs... if you're bored and want to help write scripts, here's some material:
• All the designs: DESIGNS
• Output of the simulator for each design/benchmark: doit.out (350KB)

• 10-Oct-98: another bug: at the top of p. 7 of the handout, in the equation for the "base time", Tarray, the 5pS term should *NOT* be under the square root. I.e. the expression should read Tarray = 2 * sqrt(Nbits) * 5pS.
• 8-Oct-98: project1.ps/.pdf file updated with four minor corrections (this is the version handed out in class)

• Defer to the console: Don't use a public-cluster machine remotely unless there's no one at the console.
• Use nice +19: On any machine, preface any job you expect to run for more than about 10 seconds with nice +19 to voluntarily lower its priority.
• Limit scripts: Avoid launching unattended jobs (e.g., scripts of multiple simulation) that you expected to run for more than about a half an hour.
• No parallel processing: limit yourself to at most one 6760-related simulation per person active at a time in the CoC.
