// 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: http://wwwhepix.web.cern.ch/wwwhepix/
//
// 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 inclusing 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 output of this benchmark looks like:
//
/// stressHepix
///
///
///Starting stressHepix benchmark (details will be in stressHepix.log)
///Takes 442 CP seconds on a 500 rootmarks machine (IBM Thinkpad centrino 1.4GHz VC++7.1)
///Takes 278 CP seconds on a 800 rootmarks reference machine (P IV 2.8 GHz, SLC3 gcc3.2.3)
///Takes 239 CP seconds on a 924 rootmarks machine (MacBook 2.0GHz gcc4.0.1)
///Takes 209 CP seconds on a 1056 rootmarks machine (MacBook 2.0GHz icc9.1)
///Takes 147 CP seconds on a 1512 rootmarks machine (MacPro 3.0GHz gcc4.0.1)
///Takes 142 CP seconds on a 1550 rootmarks machine (AMD64/280, FC5 gcc4.1)
///Takes 121 CP seconds on a 1828 rootmarks machine (MacPro 3.0GHz icc9.1)
