| # 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. |
