14 -20 Missing or far too brief DESIGNDOC
15 -2 Changing interfaces, each (max -6)
17 DESIGNDOC (per problem):
18 -1 Minor details missing
19 -2 Major details missing
23 -1 Gratuitous use of malloc() (e.g. for allocating a list or a lock)
24 -1 Inappropriate use of ASSERT (e.g. to verify that malloc() succeeded)
26 Problem 1-1: Alarm Clock
27 -1 Uses lock/interrupt disabling without justifying
28 -1 Uses a lock within interrupt handler
30 -2 Wakes up too often, e.g. by using semaphores with negative values
31 -1 Traverses entire list of sleeping threads every tick
32 -1 Doesn't protect data structure in timer_interrupt
33 -1 Doesn't protect data structure in timer_sleep
36 Problem 1-2: Priority Scheduler
37 -3 Doesn't use sorted queue scheduler, and don't justify why they didn't
38 -2 sema_up() doesn't pick highest-priority waiting thread
39 -1 Should use sorted queue in semaphores, unless explained in DESIGNDOC
40 -1 cond_signal() doesn't pick highest-priority waiting thread
41 -1 Should use sorted queue in conditions, unless explained in DESIGNDOC
42 -2 Yield should pick the highest-priority thread (including current)
44 +2 Used a heap or other advanced priority queue for ready_list
46 Problem 1-3: Advanced Scheduler
53 -1 No attempt to conform to existing coding style
