15-410 Project 3 Hand-in
Please make sure early that
you have enough AFS quota to hand in your project (see below for
We have had some questions about late-day strategy.
This is the most important and conceptually
challenging project in the class, and
the remaining assignments all have a substantially
lower effect on your grade than this one.
Do turn in a kernel which
runs. That is, when we boot it, it should automatically
proceed to running the shell. There should not be
any breakpoints in the idle process, for example.
Our testing process will feed commands to the shell
and observe what happens...this won't go very far
if simics is stuck at the command prompt.
Do NOT turn in a kernel which
prints thousands of messages to the log file every
time it runs. A reasonable amount of
traffic is ok, especially if it is restricted to
exceptional conditions. Or, if you're looking for
a simple rule, most processes should launch, run,
and exit without generating 20 lines of kernel
This does not mean you cannot have more
debugging information, but it does mean you will need
some way of controlling how much of it you show
to us during grading. We won't grade you on whether
your mechanism is crude or sophisticated, but you
might benefit from the latter.
When the deadline arrives, we will write-lock your hand-in directory.
You will continue to be able to view the contents.
If you need to take a late day for Project 3,
use the Late Day Registration Page,
by roughly 00:30 (it helps us if you do this as soon as you know,
i.e., you don't need to wait until 00:30).
Assuming your message is received,
the next morning somebody will unlock your hand-in
directory so you can again save your work.
Of course, your request must be in accordance with the
policy published in the syllabus.
Your files should be placed in your mygroup/p3 directory.
We should be able to
cd .../p3 ; make
to build your project. This means your files should not
be stored in .../mygroup/p3/p3 or .../mygroup/p3/proj3
(to mention two popular naming schemes we observed for P1 and P2).
Remember, if you run into "trouble with AFS", please
refer to About your 15-410 AFS Space.
cd .../p3 ; make clean
before the hand-in deadline.
Once the deadline arrives, that bootfd.img
will sit there consuming your group's disk quota
Please review the "General Considerations" above.
