*******************************
Important !!!!
*******************************
Before submitting your program on sakai, rename it to YourLastName_mm.c (replace your last name with YourLastName) and submit. Please do not submit a program named mm.c, it will result in a score of 0.
***********
Main Files:
***********
mm.{c,h}
Your solution malloc package. mm.c is the file that you
will be handing in, and is the only file you should modify. Change the file name to YourLastName_mm.c before submitting it on Sakai. Submission of a single file named mm.c will result in a score of 0.
mdriver.c
The malloc driver that tests your mm.c file
short{1,2}-bal.rep
Two tiny tracefiles to help you get started.
Makefile
Builds the driver
**********************************
Other support files for the driver
**********************************
config.h Configures the malloc lab driver
fsecs.{c,h} Wrapper function for the different timer packages
clock.{c,h} Routines for accessing the Pentium and Alpha cycle counters
fcyc.{c,h} Timer functions based on cycle counters
ftimer.{c,h} Timer functions based on interval timers and gettimeofday()
memlib.{c,h} Models the heap and sbrk function
tmp folder To store the temporary folder when you run the command ./grade-malloclab.pl -f ./mm.c
traces folder Trace files to be used for testing your program
grade-malloclab.pl This is the malloc lab's autograder. To run the autograder:
unix> ./grade-malloclab.pl -f ./mm.c
*******************************
Building and running the driver
*******************************
To build the driver, type "make" to the shell.
To run the driver on a tiny test trace:
unix> ./mdriver -V -f short1-bal.rep
The -V option prints out helpful tracing and summary information.
To get a list of the driver flags:
unix> ./mdriver -h
*******************************
Evaluating your program
*******************************
To help you evaluate your program, we add the autograder in the handout folder. To evaluate your program, do:
unix> ./grade-malloclab.pl -f ./mm.c
If your program satisfies all the requirements, you will see the following:
Part 3: Grade
Correctness: 20 / 20
Performance: 35 / 35
Style: / 10
