The BB and PM ranges were originally intended to use leading 0s to ensure all the values were the same string length, making for nice log filenames and columnar dat files. However, not everyone will do this - especially if it isn't documented. Document the intent. Make the generation and parsing of dat files robust to either method.

# DESCRIPTION
|
|
# This script runs BB_CMD (typically building core-image-sato) for all
|
|
# combincations of BB_RANGE and PM_RANGE values. It saves off all the console
|
|
# logs, the buildstats directories, and creates a bb-pm-runtime.dat file which
|
|
# can be used to postprocess the results with a plotting tool, spreadsheet, etc.
|
|
# Before running this script, it is recommended that you pre-download all the
|
|
# necessary sources by performing the BB_CMD once manually. It is also a good
|
|
# idea to disable cron to avoid runtime variations caused by things like the
|
|
# locate process. Be sure to sanitize the dat file prior to post-processing as
|
|
# it may contain error messages or bad runs that should be removed.

# The following ranges are appropriate for a 4 core system with 8 logical units

# Use leading 0s to ensure all digits are the same string length, this results
