OpenScientist Status (v11)

Relationship with AIDA

http://www.lal.in2p3.fr/OpenScientist

G.Barrand, LAL-Orsay

• v11r0 : code available now.• OpenScientist / Lab package is now AIDA-3.1

compliant. Big effort to pass from 2.2 to 3.1.• IProfile1D, IProfile2D, IDataPointSet are here.• Fitting migrated to the 3.1 interfaces, but clearly

not compleete yet.• Around management : copy for exa are not here

yet.

OpenScientist-11 / AIDA-3.1

G.Barrand, LAL-Orsay

• Rio (v4r0) : a light and clean rewrting of the ROOT IO. 10 klines of code (against 200klines with ROOT/Core) to write/read an histo.

• Abstract interfaces (Rio::IObject, IClass, IDirectory, IFile, etc…)

• (Able to read LHCb data with it (GaudiRioDb)).• Protect the io (tobuf, IBuffer) without doing carpet

hiding (using exception). • Etc…

OpenScientist-11 / Rio-4.0

G.Barrand, LAL-Orsay

• Read ROOT files with TH[1,2]. But do no write the Lab histos as TH (since AIDA histos are more rich that the TH (handling of entries per bin for example)).

• Able to convert hbook files (h1d, h2d, rowwise ntuples) to Lab rio/root files.

• A MySQL driver had been introduced : able to read histos stored with FreeHEP. But fare from being compleete.

• AIDA / XML : no progress yet.

OpenScientist-11 / Persistency

G.Barrand, LAL-Orsay

• Improvement of the GUI.– GUI constructed from an XML description.– Tab stack, toolbar, tooltips, icon on buttons, user popup menu on the

Inventor viewer.– All that on the four toolkits Windows, OpenMotif, gtk+, Qt.– (Be able to save back the GUI description)

• InventorViewer : elastic rectangular draggable box :– Viewing mode : zoom.– Picking mode : collect objects.

• gl2ps : plots and 3D graphics.• (GUI organization very similar to jas3 !!!)

OpenScientist-11 / GUI, graphic

G.Barrand, LAL-Orsay

• Geant4/examples/extended/analysis/AnaEx01 updated to AIDA-3.x.

• OpenScientist / G4Lab, G4LabSimple exa improved. • A G4UIOnX exists now (similar to the other G4UIs :

G4UIterminal, G4UIXm, G4UIWin32, etc…) but needs DLLs on Windows for Geant4 !

• A package cloner facility exists to easily create its own “G4Lab”.

OpenScientist-11 / Geant4

G.Barrand, LAL-Orsay

• OnX (Coin, HEPVis) used to construct the Panoramix event display.

• Lab : available in the same interactive environment.• Gaudi / SoStat package : to plot the Gaudi

AIDA::IHistograms with HEPVis/SoPlotter in a GUI constructed with OnX.

• Connection done with DaVinci (the project to handle physic analysis software for LHCb).

OpenScientist-v11 / LHCb

G.Barrand, LAL-Orsay

• Huge progress in all parts.

• But fare from completion…(assuming that an analysis system if ever compleete).

• (Man power expected in autumn !)

OpenScientist / Conclusions

G.Barrand, LAL-Orsay

AIDA Answer to people that are fanatic of the project.

G.Barrand, LAL-Orsay

• Demo with OpenScientist / Lab implementation.• Sorry Rene, you are no more the only one in this universe, to

book, fill, plot and store histos. • And some do it with a fare better architecture and implementation

than yours (at least without some TClass::Draw, etc…).

To Rene Brun (ALICE) : it does not work

G.Barrand, LAL-Orsay

• Comparison of a “main” to book, fill, plot, store with AIDA and with Gaudi :

• AIDA (see tutorial AIDA example).• Gaudi (see GaudiExamples histogramming).• Pere (as plenty of people at CERN) confuses simplicity

with naivety.• Is it possible to design a flexible and evolutive

framework simple for physicist AND software engineerers ???

To Pere Mato (LHCb) : it is too naive

G.Barrand, LAL-Orsay

• LCG / PI introduces a new partial implementation.• Why partial ? Because the AIDA::IFactories, ITree are

discarded (along the IPlotter ?).(How users will plot, store ?)

• Clearly (like for Anaphe choices) LAL and SLAC implementation will not be taken into account.

• Is PI::AIDA going to be one more selfish CERNery ?• But Vincenzo (representing the LCG executive ?), at

least, had decided to be at the workshop….

Vincenzo Innocente (CMS)

G.Barrand, LAL-Orsay

ATLAS ????

G.Barrand, LAL-Orsay

• “all day” work of improving the interfaces.

• Some dirty linen washing with CERN.– Avoid CERN demolishing what had been achieved

so fare.

What I expect from this workshop

G.Barrand, LAL-Orsay

• Priorities :– Have a more compleete implementation.

– Integration within LHCb (see Thursday).

– Interoperate with other implementations.

• Not priorities :– Bear a new partial implementation.
