• CS415 2005sp

What is this class about?

• Apply the theory learned in 414
• Synchronization, Networking, and many others
• C hacking for fun and profit
• Build a system from a virtual ground
• Learn to debug a complex system
• cutting-edge systems design
• What is on the cutting edge now?

The Project Ad-hoc networking

• Ad-hoc networking
• Establishment and maintenance of a communication
  network in the absence of a fixed infrastructure
• Normally done over wireless (eg 802.11b)
• We will build a simple ad hoc network and an
  application over it
• We have suggested applications, but you can come
  talk to me about proposals

4
Where do we start?

• Need an environment over which to build
• You will build a simple virtual OS over NT
• We provide a bare environment like at boot time
• Start with lightweight threads
• Need to add context switches
• Need synchronization
• Need a scheduler
• Instructions posted on web. Follow them.
• Due in two weeks (11 Feb)

5
Where do we go from there?

• Part II Preemption, Alarms, and Schedulers
• Part III Unreliable Networking
• Part IV Reliable Networking
• Part V Ad-Hoc Networking
• Part VI Ad-Hoc Application
• Suggested
• Messaging
• Distributed Files
• CPU sharing

6
Groups

• Size 2 or 3
• We will not take the size of your group into
  consideration when judging your work
• ie. Smaller groups are at a disadvantage
• See the guidelines online for tips in how to work
  well (or poorly) in groups
• The grade for the group will be your grade

7
What if my code doesnt work?

• As long as there is good faith effort
• about 50 of the grade for that part of the
  project
• The TAs will not fix it
• We will not be handing out solutions
• You will be building your whole system from
  scratch

Grading

• Parts I II 10 each
• Parts III IV 15 each
• Parts V VI 20 each
• 10 subjective
• Challenge sections for the Adventurous
• Extra components in some parts
• Will be examined and commented on if the base
  work is sufficient
• Will not be graded
