Malloclab (Memorylab)

Copyright (c) 2002, R. Bryant and D. O'Hallaron, All rights reserved. May not be used, modified, or copied without permission.

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.

• mdriver.c: The malloc driver that tests your mm.c file

• traces/*.rep: Trace files

• 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

Building and running the driver

• To build the driver, type "make" to the shell in the src directory

• To run the driver on a tiny test trace:

  devel@getnoo ~/malloclab $ mdriver -V -f traces/short1-bal.rep

• The -V option prints out helpful tracing and summary information.

• To get a list of the driver flags:

  devel@getnoo ~/malloclab $ mdriver -h

• To test all traces:

• ./mdriver -V

performance

• my Implementation scored 85/100. Which was very good!
