This file describes the steps to perform a batch of measurements, then extract runtime data
and generate speedup graphs with gnuplot.
NB: this isn't a shell script, you need to cut and paste (and modify) the lines below

> # start a batch of measurements in the background
> sh runItBaldur.sh &
> # once finished, extract the data like this (adjust "rows" to output generated by MatMultPM, or of your own program)
> cat LOG | sed -ne '/PEs/H;/rows time/H;${G;p}' | sed -e 's/^.*PEs \([0-9]*\).*$/\1/;s/^rows.*= \([.0-9]*\).*$/\1/' | sed -ne '/^[.0-9]*$/{h;N;H;p}' | sed -e '/[.]/a\X' | sed ':a;N;$!ba;s/\n/ /g' | sed -e 's/X/\n/g' |  sed '$d' | sort -n -k 1 >rt.dat
