ROOT Team Meeting

Friday 17 Nov 2006, 11:00 → 12:30 Europe/Zurich

32-SC22

11:25 → 11:30 5.13/06 release status (to be done and left for 5.14)

Speaker: Axel Naumann

CINT and I/O (Philippe) ============================ CINT: For the Nov 22 release branch or the dev release we plan to upload the snapshot of Cint/Reflex with a modified build system, so we get binary compatible libCint and libCintNew. We expect to have all but variables and functions converted to Reflex for the November release. We expect to be done with the functions and maybe even the variables for the production release. ===>NOT implemented New build system (CINT5 +7 ) for 5.14 Changes to CINT5 to make compatible with CINT7. Axel will present status report in 2 weeks TTree/IO: - Update the implementation of the AutoAppendToDirectory feature so that instead of having to undo it in the place we don't want it (for which we do not have an exhautive list), we do it only where we want it (user call to constructor and load from file via TKey). - Enable the memory clean in TTree to have the memory leak of the contained data objects. - Loading cintdlls automatically (from the I/O) to avoid using an EmulatedCollectionProxy with a compiled STL container (different layout) and warn the user when he should have created a dictioanary for a stl container that is not provided by default (like vector<MyClass>) - Update SetBranchStatus("*",1) so that it really enables all branches (instead of __only__ the one with a leaf). ===>NOT implemented Math (Lorenzo): =============== Apart from bug fixes and eventual requests from the experiments for SMatrix and mathcore, the major planned work is: - to develop and integrate in ROOT new fitting classes with the aim to replace the TVirtualFitter. The plan is to start integrating them in CVS at the end of October/ beginning of November. The initial functionality should be at least what the TVirtualFitter provides right now. Implement also new functionality in the Fit panel, like a minimization sub-p anel, using the new classes. TF1 should also started to be then modified, maintaining backward compatibili ty, to use the new interfaces and classes. ===>NOT done - Extend Mathmore adding the algorithm from GSL for multidimensional functions ===>will be done today - integrate Unuran. What is missing before putting in CVS is the porting on Win dows. The code compiles, the problem is more the build system. ===>Done. Must still optimize Makefile on Windows - new developments are foreseen also in RooFit ===>NOT done and TMVA. ===>done Graphics : (Olivier): ========================== OpenGL: - TGLStackPainter, - TGLTGraph2DPainter. - Clipping box/plane to visualize the inside of TH3, TF3, Surface, Lego. ===>NOT done ===>Timur next Monday. New stuff for 5.14 Basic Graphics: - Integrate TSpectrum2Painter. - Integrate TGraphPolar. - Integrate TPie. ===>Done (still bits in TPie) Plus (if time): - Text clipping in PS. A text clipped in PS disapear completly ===>in 5.14 - SetRightMargin() does not work on TH3 drawing. - Problem with Label and Tick mark size on axis with labels defined using SetBinLabel(). - TGraph2D: With option TRI1 the color palette does not follow the same rules as option SURF1 or COL. ===>NOT done GUI (Ilka): ============ below is included the GUI planning (apart from unforeseen bug fixes and/or user requests): - Porting new features included in xclass library in TGFont and TGTextLayout c lasses. - new TGHtml class development. ===> NOT done - new TGAnalogMeter development. ===>done - To make possible cut and paste from a text entry widget to/from an external window. ===>done - Remove modal dialog restriction of the new Fit panel. ===>done - Complete TFitParametersDialog with missing functionality. ===>done partially - Implement new functionality in the Fit panel according to the new virtual fi tter development (Minimization tab). ===>postponed CORE (Fons) =========== - TSystem interface to machine parameters: - cpu info (type, number of cores, load, etc) - memory (total installed, active, shared, paged, used by current process, etc) - network (10/100/1000 eth, av load, etc) All this is needed for precise monitoring of PROOF workers by MonALISA. It is highly OS dependent. ===>Done (still missing for Solaris). - Parallel sockets (TPSocket) that work also when only one port in the firewall is open, current version became un-usable due to strict firewall rules enforced the last few years. First version ready, under review now. ===>Not done - Class supporting atomic operations needed for efficient (better than mutex locking) reference counting in a multi-threaded environment ===>Done - Plugin manager changes as discussed before (self describing plugins). Will probably not be ready by end of this year as still open to discussion. ===>Not done (special meeting in January) ===>for 5.14 move libThread in libCore and use TAtomicCount PROOF (Fons) =========== - Fix all open bugs found during the ALICE test ===>Many fixed - New time slice based packetizer Not yet in production ===>may be in 5.14 (as an option). - Introduction of monitoring interface (need TSystem extensions mentioned above) ===>Done - Running more ALICE tests ===>?? in progress - Performance dashboard ===>Done

11:30 → 11:50 The new gif and tutorials directories

It was decided to create a CVS project where all gif, jpg, etc files used by THtml to produce the reference manual will be stored. Currently these files are on rene's machines and distributed with the html.tar.gz files. It was decided to extend the current $ROOTSYS/tutorials directory with new sub-directories reflecting a given functionality (eg graphics, fitting, tmva, etc). This will imply changes in Tutorials.html

11:50 → 12:10 Presentations scheduled for next meeting

At the next meeting (December 1) we will have the following presentations -Extension of the VirtualFitter interface by Lorenzo -Status of CINT/Reflex by Axel -Getting Started manual sketch by Ilka
