Output

Each run of the benchmark on a particular system results in a set of output files. (Default prefix is b_eff.)

• b_eff.prot a detailed protocol
• b_eff.short a short version of the protocol
• b_eff.sum a short overview
• b_eff.plot a file with data for plotting
• b_eff.gps a script for gnuplot
• b_eff.tex a LaTeX source file to create a benchmark report

With only 3-steps you can create a nice benchmark report with charts. What you need is:

• Gnuplot (version 3.7 or newer)
• an installation of LaTeX
• b_eff.plot b_eff.gps b_eff.tex

Commands:

 
          gnuplot b_eff.gps
          latex b_eff.tex
          dvips b_eff.dvi
