Here's how to get started with the malloclab on jupyter.
# First, get to your jupyter.bennington terminal, and create a folder to work in. Then : $ wget https://cs.bennington.college/courses/fall2020/systems/code/malloclab/malloclab-bennington.tar $ tar xvf malloclab-bennington.tar $ cd malloclab-handout $ make $ ./mdriver -v -t . -f short1-bal.rep $ ./mdriver -v -t . -f short2-bal.rep $ ./mdriver -v
The task is to implement malloc, free, and realloc, which allocate, free, and resize memory blocks on the heap, using the API in mm.c.
The mm.c provided contains a "naive" somewhat working implementation, which just returns the next block of memory without ever freeing anything.
mdriver program runs trace files that exercise the program,
asking for different amounts of memory, and measuring how quickly
the program can provide them.
short2-bal.rep trace files give easy
tests, provided for debugging. When running them, the
-t . option
means "look for a trace file in this folder".
The config.h file defines a location for some default traces which
I've put into /home/mahoney/malloc_traces/ ; those are what's run
when you just type
./mdriver -v. On the naive implementation,
some of those tests run out of memory.
