There is an example of a gif included in this directory for your viewing pleasure.
There is a converted log and an unconverted, old format log found under WQ_logs. You can start this example on step 3 with the converted log.
To make a gif visualization of a work_queue process given just cctools and the required dependencies (see README), do the following:
1.) Run a work_queue process and keep the whole log
Move to the directory in cctools/work_queue/apps/work_queue_visualization/example (where you are reading this file)
You can either run a process with a short log, as this example will explain, or run your own process and keep the full log as described at http://ccl.cse.nd.edu/software/manuals/workqueue.html
For this example, run:
python work_queue_example.py dummy_file1.txt dummy_file2.txt dummy_file3.txt
This will create a log call "wq.log". Now, you'll want to:
cd ..
to get out of the example directory and back to the
cctools/apps/work_queue_visualization directory.
2.) Convert the log to a viable form.
If you just ran work_queue to obtain a log and have cctools version 4.4+, the log will be new enough to use. If you skipped step 1 and
though "I'll just use an old log from an old work_queue process", or have cctools version 4.3 or lower and somehow have this tool, convert the log using:
python log_converter.py your_log filename_for_converted_log
3.) Run visualize.py
To create the actual gif, run:
python visualize.py viable_log_name output_gif_name
where output_gif_name does not need a ".gif" extension. This process may take awhile.
In this example, the exact line would be:
python visualize.py example/wq.log trial
and the gif would be found at trial.gif
4.) View the animation
Use ffmpeg or a browser to view the actual animation you created, trial.gif
