  1. Generator Services review and planning meeting Witek Pokorski 25.04.2012

  2. Outline • General news • Progress reports and plans • GENSER and validation • collaboration with LPCC (MCPLOTS, P. Skands) • HepMC • Summary • Discussion

  3. General news • new mailing list for all Generator Services announcements • genser-announce@cern.ch • please subscribe • MCDB subproject stopped in the context of Generator Services • CMS was the only user • mid 2011 CMS decided to migrate away from MCDB • with no production use from any of the experiment, our support for MCDB has been dropped • project still running but not in the context Generator Services

  4. GENSER - Progress report (1/2) • moved to SVN completed (internal scripts) • ~50 new generators/versions installed over the last year • experiments regularly requesting new generators • installation done according to the needs • platforms • i686-slc5-gcc43-opt, x86_64-slc5-gcc43-opt • x86_64-mac106-gcc42-opt, i386-mac106-gcc42-op • builds for MacOSX still a bit of a problem

  5. GENSER - Progress report (2/2) • new degree of freedom needed to be introduced: version of HepMC • MCGenerators_hepmc2.03.11, MCGenerators_hepmc2.06.05, 06, 07, 08 • LCGCMT configuration with generator interfaces pointing to MCGenerators_HepMC2.06.XX for CMT users • configurable using $(HepMC_config_version) variable • rpath issue has been raised in the context of CVMFS • problems seems to come from autotools (autolib) • Anton K. has a script which solves it (used successfully in MCPLOTS) • issue of _dbg platforms (links) recently raised

  6. GENSER – Open questions • when do we drop 2.03.11? • how many versions of HepMC to support? • can we come up with an 'official' list of generators we build on MacOSX? • what do we do with rpath? • can we consider applying Anton's script (used in MCPLOTS) as a solution? • can we handle _dbg platforms at the level of CMT requirement files?

  7. GENSER - Plans • continue installation of new generators/versions • implement tests for new generators • internal for GENSER: • organization of _hepmc trees • separation in AFS volumes • finalization of MCGenerators_hepmcxxx installation tool

  8. Validation - Progress report • regression tests available for more than 90% of generators • tests results linked from the table of generators • HepMC Analysis Tool based regression testing now done for the new versions of several most important generators • some improvements needed in the generating script • need to review the dependency on MCPLOTS scripts • physics validation done very extensively (and very well) by MCPLOTS • Rivet-based analysis for validation against LHC (and older) data

  9. MCPLOTS (P. Skands) • very nice collaboration between Generator Services and LPCC

  10. Validation - Plans • implement missing regression tests for recently added generators • extend existing regression tests for better coverage • improve GENSER interface to HepMC Analysis Tool • continue testing and checking, but main validation done by MCPLOTS (P.Skands) • LPCC funding very appreciated

  11. HepMC – StatusLynn Garren • 2011-12-06    HepMC 2.06.06 Add the ability to build with cmake (preferred for MacOSX) Remove fio/PythiaWrapper.cc and inline getPythiaCrossSection (bug #88376) Move Pythia and Herwig examples to examples/fioexample_BuildEventFromScratch does not use CLHEP vectors • 2012-01-11    HepMC 2.06.07 Cmake is now the preferred build method for all platforms.fix a typo in the error report for GenEvent::use_length_unit (sr #125496)Local variables in some headers have been renamed to avoid warnings when compiling with -Wshadow: GenParticle.h, GenVertex.h, PdfInfo.h, SimpleVector.h, SimpleVector.icc (sr #125483)add examples/pythia8 • 2012-02-16    HepMC 2.06.08 because of requested changes in 2.06, IO_GenEvent::use_input_units() was not setting units for an input stream. This bug affected only 2.06.x and is now fixedGenEvent::define_units() can be used when the units in an event do not match the default units. Define_units() does not convert momenta or length.Add more testing of the Units functionality.

  12. HepMC Outstanding requests Lynn Garren • Reduce size of events by selecting only "interesting" particles.  Have to make sure remaining particles are attached to the appropriate vertex.  Some vertices may become superfluous.   Otherwise, fairly straightforward • Rework HepMC data members so they play nicely with root.  Definitely can be done. Exploring options. 

  13. Milestones from last meeting DONE DONE DONE DONE + RIVET/MCPLOTS DONE ONGOING

  14. Proposed milestones

  15. Manpower situation • technical student Anton P. finished his studentship end of January 2012 • current situation • LCG Russia: 16 months FTE per year • WP: 0.1 FTE • L. Garren – HepMC, external contribution from FERMILAB • this is the minimum needed to run routinely Generator Services • very valuable support from LPCC for the development of MCPLOTS

  16. Summary • project running routinely • GENSER stable • testing constantly extended • collaboration with MCPLOTS (P. Skands) • testing of beta versions of generators • comparison to LHC data • looking forward to definitely retire HepMC 2.03 • ROOT I/O developments in HepMCongoing
