Running the ROOT benchmark suite

The ROOT standard distribution kit includes a long list of test programs. Some of these test programs are used to benchmark the performance of ROOT, The suite includes

All benchmarks report the total RealTime and CpuTime and also a performance number (ROOTMARK). All stress programs have been normalized to 800 ROOTMARKS on a P IV 2.8 Ghz with Linux and gcc3.2.3. If you have interesting benchmarks (new machine, compiler) with the complete test suite, please send the results in html source format to rootdev@root.cern.ch. For those interested to run the ROOT benchmark suite, here are the instructions:

First step: install ROOT itself

The complete instructions are available at How to install ROOT. If you are interested only by the benchmark suite, you can install the default minimum configuration shown at the bottom of this page, otherwise configure with the default version. To get the source, do, eg 
     prompt% ftp root.cern.ch
     User: anonymous
     Password: 

     ftp> cd /root
     ftp> bin
     ftp> get root_v5.13.03.source.tar.gz
     ftp> bye

     prompt% tar -zxvf root_v5.13.03.source.tar.gz
     prompt% cd root
     prompt% ./configure --disable-globus 
     prompt% make -k
        this step will take between 10 to 30 minutes.
        if you have a multi-core, you can speedup the installation
        make -j 2 -k  (for 2 cores)
        make -j 4 -k  (for 4 cores)

Second step: run the benchmarks

     prompt% export ROOTSYS=$PWD  (the root directory)
     prompt% export PATH=$ROOTSYS/bin:$PATH  (or setenv)
     prompt% export LD_LIBRARY_PATH=$ROOTSYS/lib:.:$LD_LIBRARY_PATH
     prompt% cd test
     prompt% make
     prompt% 
     prompt%    you are now ready to run the benchmark suite
     prompt% stress -b
     prompt% stress -b 30
     prompt% stressFit
     prompt% stressSpectrum
     prompt% stressLinear
     prompt% stressGraphics
     prompt% stressGeometry

stressHepix

HEPiX-HEPNT is an organization comprised of UNIX and Windows support staff in the High Energy Physics community. One of the HEPIX activities is to gather knowledge about new hardware and software and to recommend common solutions (eg Scientific Linux) see: HEPIX web site.

This benchmark suite has been implemented following several requests from HEPIX members interested by a collection of benchmarks representative of typical applications.

stressHepix is a single benchmark including several standard ROOT benchmarks with a mixture of CPU intensive tests and I/O tests. The output of stressHepix is one single number (the ROOTMARK). A Pentium IV 2.8GHz running Linux SLC3 and gcc3.2.3 runs this benchmark with a reference at 800 ROOTMARKs.

To build the executable for this benchmark, do 

   cd $ROOTSYS/test
   make
The default configuration of ROOT is enough. The ouput of this benchmark looks like:
