23.3 Taking the timings and benchmarking

Benchmarking differs from testing only in that program timings are computed and compared with reference timings. Calling the script as

TTEST --timings

performs the test, calculates the CPU and wall clock timings, and writes the raw results to the TESTTIMINGS.sysname.nodename file. Auxiliary scripts Tbtim and Tblist help to convert this data to a more readable form and produce summaries as LATEX tables. The Tbtim script creates a summary of benchmark results for a given computer platform from the original timings file. Tblist produces benchmark comparisons of different platforms. The corresponding timings files must be provided as arguments to the Tblist script. For more details and options, see TBTIM –help and TBLIST –help.
