Git-Benchmark Scripts
which are placed in src/: git_benchmark.py grep_ext4.sh grep-f2fs.sh
You'll need to install the dependencies before running.
This section includes the files:
runner.sh
git_benchmark.py
grep_ext4.sh
grep_f2fs.sh
reset.sh
runner.sh is a wrapper that uses Git-Benchmark scripts
reset.sh is for resetting
the SD card to start the tests over (deletes the SD card's contents).
To run the tests, I created runner.sh to run tests for both EXT4 and
F2FS, so that it can run in background. You will need to change the
variables in the file. Below is a summary of them.
SRC_REPO: the path to git repo on your computer to pull from.
DEST: the path to be aged
OUTPUT_FILE: the file you want the script to write to
TOTAL_PULLS: total number of pulls you want performed
PULLS_PER_TEST: the step/amount-of-pulls you want to perform grep-tests at
TEST_SCRIPT: the script that performs the grep tests
PATH_TO_AGED:
the path to the aged directory (you may need to create one)
AGED_BLK_DEV:
the device partition to age (found in /dev/)
PATH_TO_UNAGED:
the path to the aged directory (you may need to create one)
UNAGED_BLK_DEV:
the device partition that won't be aged (found in /dev/)
Note: These variables are changed half way through the script. Make sure you
change those as well. First half of the scipt is for F2FS, the other half is
for EXT4.
This directory contains the data from running the experiments. Below is a description for each of the files.
plots.gp:
this file can be loaded in gnuplot to plot the results into a graph.
data.dat:
the data for each run, formatted for gnuplot for plots.gp.
f2fs_aged_out.txt:
the raw data (in text) from the F2FS runs, with each failed pull line
deleted, except for the first and last in each section.
ext4_aged_out.txt:
the same as the above, but for the EXT4 runs.
Contains files for creating the report that was turned in for the course. Uses a makefile to generate the PDF from a LaTeX file.
