2011-07-14bb-matrix: correct BB and PM number canonicalizationDarren Hart
The bash string operation ${BB##*0} was greedy and in addition to converting "02" to "2", also converted "20" to "", causing all builds for a BB value ending in 0 to run with BB_NUMBER_THREADS=1.

2011-07-12bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinationsDarren Hart
The script will run a bitbake command, building core-image-minimal by default, for various combinations of BB_NUMBER_THREADS and PARALLEL_MAKE. It records all relevant metrics of the TIME(1) command for each combination in a data file. The script can be used to visualize each of these metrics via a 3d surface plot, either solid surface or wireframe with a value-map projection on the XY plane.
