====== BG@HEPlib manual ======
(S.Chekanov, E.May)

{{:hpc:bghep:bghep1.png?1600x20|BG@HEPlib library}}

ANL BG-HEP library is designed to run CPU-intensive HEP calculations on the BlueGene/Q supercomputer (Vesta/Mira) of [[https://www.alcf.anl.gov/ | Argonne Leadership Computing Facility]].  
The main features of the BG@HEP library are:

  * Many packages have been redesigned removing ROOT, HBOOK  and CERNLIB calls
  * Monte Carlo / NLO programs redesigned to use MPI for random seeds and outputs on multiple cores
  * The default output of event records is [[https://atlaswww.hep.anl.gov/asc/promc/| ProMC file format]] 

The following HEP libraries are supported:


  * CERNLIBlite  - a light version of [[http://www.desy.de/~chekanov/cernlib/ | CERNLIB]] (without HBOOK, my slimmed version SC)
  * fastjet (v 3.03) -  jet library [[http://fastjet.fr/ | Fastjet]]
  * hepmc  (v 2.06.09) - [[http://lcgapp.cern.ch/project/simu/HepMC/ | HEPMC library]]
  * lhapdf5 (v5.9) - [[https://lhapdf.hepforge.org/ | LHAPDF the Les Houches Accord PDF Interface]]
  * lhapdf6 (v6.4)
  * [[http://mcfm.fnal.gov/ | MCFM v.6.7]] - NLO program with ProMC output for ntuples
  * jetphox (v3.02) - A JetPhox NLO program
  * promc   (v1.3) - [[https://atlaswww.hep.anl.gov/asc/promc/ | ProMC data I/O library]]
  * protobuf (v2.5) - (comes with ProMC)
  * pythia8 (v8180)- Pythia8 with [[https://atlaswww.hep.anl.gov/asc/promc/ | ProMC]] output
  * [[http://lapth.cnrs.fr/PHOX_FAMILY/jetphox.html | jetphox]] 1.302  - NLO program with [[https://atlaswww.hep.anl.gov/asc/promc/ | ProMC]] output 
  * zlib (v2.09)

To setup the library, run this setup script:

<code bash>
source /home/chakanau/public/BG-HEP/bghep_setup.sh
</code>

This will setup the above libraries. Each library has a "Makefile" which can be compiled and run a program on BlueGene/Q.
Look at this "bghep_setup.sh" to see location of each library.


A list of Monte Carlo simulations and NLO programs generated on BlueGene/Q (Vesta, ANL) is listed on the **[[http://atlaswww.hep.anl.gov/hepsim/ | =HepSim= event repository]]**.

You can download this package as [[http://atlaswww.hep.anl.gov/asc/download/BG-HEP.tgz |BG-HEP.tgz]]**.
