ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Session IV: Innovative (Algorithms and) Tools V.Fine, BNL, USA & JINR, Dubna

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory What is tools Theory Algorithm Computer code Program + user’s requirement + service = Tool – is an algorithm that is implemented with some working computer program, satisfies some extra user requirements and is used more then 1 place (excluding the program's authors)

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Summary “Tools” (2 nd ) part of Session IV There were 3 oral (tools) sessions, 12 talks (7 speakers), and 3 posters: Status reports Overviews Original results

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Status reports Geant4 – by V.Ivanchenko CMS – by L.Tuura AIDA – V.Serbo Anaphe– M.Sang It would be interesting to see some information about the users of the systems in questions and their feedbacks

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Overviews Ignominy – by L.Tuura GEANT4 Physics validation by H.- P.Wellisch OO software for Simulation and Reconstruction – by P.Acre

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Original works ROOT-related (Alice, US Atlas) 3 talks (of 12) by Rene Brun, by Yu. Fisyak, by V.Fine JINR – unusual work, application of modern technique to solve some economic problem – by T.Tyupikova Institute for High Performance Computing and Information System – Some approach to Quantum System Evolution Simulation (poster)

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory HEP experiments CMS – shares with us several talks. There were 6 CMS-”related” presentations ATLAS – 1 talk (OO model of the geometry) ALICE - 1 talk (OO model of the geometry) Alas no talk from the running experiments ( RHIC / FermiLab for example)

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Hot issues There were several talks regarding the suitable OO model of the HEP detectors, that can be used and re-used for the purposes of the simulation, reconstruction and visualization as well. –R.Brun The ROOT Geometry package –Yu. Fisyak OO/C++ Reconstruction Model Based on GEANT3 –P.Arce “Simulation Framework and XML Detector Description Database for CMS Experiment

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Cross platform Why ? There is no argue Unix vs Windows anymore. To be healthy To use Windows man / computer power So far there is no clear answer how to achieve this. There was only one talk devoted to this problem. Do we want to be healthy?

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Summary There were present some summaries and overviews, those lack of new information The original presentations were interesting and I would like the next organizing committee to encourage people to bring their new (may be small) job to the next Workshop.

ACAT 2002, Moscow June 28, 2002 V.Fine Brookhaven National Laboratory Workshop was very interesting successful and fruitful Special thanks Moscow State University and Joint Institute for Nuclear Research. And all participants as well.
