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

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/fio example_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

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.

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 HepMC ongoing
