The LHC Computing Grid Project (LCG)

RTAG9 (MonteCarlo Generators) June 2002

 

Documents: final report (CERN-LCG-2002-024)

 

Chair: Albert De Roeck

Mandate:

To best explore the common solutions needed and how to engage the HEP community external to the LCG it is proposed to study:
bulletHow to maintain a common code repository for the generator code and related tools such as PDFLIB. 
bullet The development or adaptation of generator-related tools (e.g.HepMC) for LHC needs. 
bullet How to provide support for the tuning, evaluation and maintenance of the generators. 
bullet The integration of the Monte Carlo generators into the experimental software frameworks. 
bullet The structure of possible forums to facilitate interaction with the distributed external groups who provide the Monte Carlo generators.

Timescale

bullet

1 months for the initial report

bullet

2 months in total for the final report to SC2

Makeup: 

reps from each of the LHC experiments (ATLAS: Ian Hinchliffe, CMS:Albert deRoeck, LHCb: Nick Brook, ALICE:??)
rep from CERN theory group: (Michelangelo Mangano)
external generator author (Lonnblad-PYTHIA??;Seymour-HERWIG??)
simulation expert (in broad sense, not only G4) ?

Guidance:

The physics MC generation will be a rather time consuming effort, and allocation of resources as well as the identification of common strategies cannot wait the arrival of the first data. The integration of MC physics simulation with the plans for computing at the LHC will be essential for an optimal and coherent use of the developed tools
