  33 2004-03-20  Constantin Loizides  <loizides@hansa00>
  34
  35         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressorHelper.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
  36         Removed GCCVERSION string from code. Replaced by compiler internal
  37         macro __GNUC__ which is 3 for gcc version >3.
  38
  39         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.h:
  40         Added zvertex.
  41
  42 2004-02-25  Anders Strand Vestbo  <vestbo@hansa00>
  43
  44         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h:
  45         Added some additional printout features in PrintCompRatio.
  46
  47 2004-02-25  Constantin Loizides  <loizides@hansa00>
  48
  49         * /alice/cvs/hltcvs/level3code/comp/Makefile:
  50         Added support for profiling, see Makefile options, there are now to targets for libs, standart and old behaviour is building of shared libs, static builds .a libs which can be used for profiling (gprof).
  51
  52 2004-02-17  Anders Strand Vestbo  <vestbo@hansa00>
  53
  54         * /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
  55         Added a flag in Init function to test whether this function has been
  56         called by the same object before. If that is the case, all internal
  57         arrays needs to be cleared before filling them again. Such a check is
  58         necessary e.g. when using AliHLTTrackArray::RemoveLast in which the
  59         object is _not_ deleted, but merely reused.
  60
  61 2004-02-07  Constantin Loizides  <loizides@hansa00>
  62
  63         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx:
  64         Two function calls changed to reflect latest changes in AliHLTTransform.

  67
  68         * /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
  69         Cosmetic change.
  70
  71         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h:
  72         Included previously removed code in the WriteRemaining and ReadRemaining
  73         functions, which keeps the possibility of _not_ compressing the remaining
  74         clusters but storing them as is, meaning with a full floating point
  75         precision. This has been done mostly for debugging/verification purposes.
  76
  77         Also introduced a new flag, DoNotCompress(), which tells the compressor
  78         to run the chain without compressing any of the data. Also for debugging
  79         purposes only.
  80
  81         * /alice/cvs/hltcvs/level3code/comp/AliHLTModels.h:
  82         Reflecting the latest changes in compressing remaining clusters.

  85         Added possibility to externallly specify which precision to store
  86         the remaining clusters in the AliHLTCompress::CompressRemaining function.
  87         This is done by setting the number of bits in
  88         AliHLTDataCompressorHelper::SetRemainingBitNumbers.
  89
  90 2004-01-28  Anders Strand Vestbo  <vestbo@hansa00>

  93         Changing the names of data members AliHLTClusterModel::fDSigmaY2 and fDSigmaZ2
  94         to fDSigmaY and fDSigmaZ, in order to reflect the fact that their are really
  95         the sigmas and not sigma squared.
  96
  97         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx: Bugfix.
  98
  99 2004-01-25  Anders Strand Vestbo  <vestbo@hansa00>

 104
 105         * /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
 106         Bugfix
 107
 108         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h:
 109         Added function to make a pass over the data and calculate how many bits
 110         is required to encode the residuals (assuming no further compression).
 111
 112         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h:
 113         Added function to calculate entropy of the quantized residuals.
 114
 115 2004-01-23  Anders Strand Vestbo  <vestbo@hansa00>
 116
 117         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompLinkDef.h, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressorHelper.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressorHelper.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
 118         - Changed back to the old method for quantizing the residuals, since
 119         there appeared some strange behaviour when running the code in multi-event
 120         mode. It still remains a mystery, so this problem has been postponed and will
 121         be solved sometime in the future.
 122         - Removed some obsolute code as a result of moving the handling of remaining
 123         clusters from AliHLTDataCompressor to AliHLTCompress.
 124
 125 2004-01-22  Constantin Loizides  <loizides@hansa00>
 126
 127         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressorHelper.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressorHelper.h, /alice/cvs/hltcvs/level3code/comp/AliHLTFitUtilities.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.h:
 128         Introduced new class AliHLTDataCompressorHandler, which is static
 129         and capsulates all static calls from the former Compressor
 130         class in order to remove some very nasty dependencies.
 131         The other classes had to be adapter to call the
 132         right static function.
 133
 134         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompLinkDef.h, /alice/cvs/hltcvs/level3code/comp/Makefile:
 135         Changes to compile for MACOSX at core Makefiles. Check for
 136         $(ARCH) and -D$(ARCH). In order to solve cyclic dependencies
 137         for libs (which is _very_ bad, but the Linux linker is friendly)
 138         a few changes have to be done (moving files around) which
 139         we dont do at the moment. SO: Linux users should see _NO_
 140         difference!!!
 141
 142         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx:
 143         Paranoic change :-)
 144
 145 2004-01-09  Anders Strand Vestbo  <vestbo@hansa00>
 146
 147         * /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
 148         New functions for quantization of pad and time.

 151
 152         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
 153         Writing remaining clusters to file is now moved to AliHLTCompress class.
 154         The clusters are now written using the bitio functions, as the data sizes
 155         used has been minimized.
 156
 157 2004-01-02  Anders Strand Vestbo  <vestbo@hansa00>
 158

 160         - Modified how the remaining clusters are written (this will probably change
 161         again soon).
 162         - Added seperate fields for storing the pad and time shape -> can specify
 163         seperately how many bits should be used for the two cases.
 164
 165 2003-12-21  Anders Strand Vestbo  <vestbo@hansa00>
 166
 167         * /alice/cvs/hltcvs/level3code/comp/AliHLTModels.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx:
 168         Changed the track parameters in the compression scheme. There are now 5
 169         floats (instead of 6) used to encode the properties of the helix. These
 170         are defined (as before) in AliHLTModels.h.
 171
 172         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.h, /alice/cvs/hltcvs/level3code/comp/AliHLTFitUtilities.c:

 176
 177 2003-11-18  Constantin Loizides  <loizides@hansa00>
 178
 179         * /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
 180         This class has to be reworked in order to compile with newer AliRoot versions after june 2003. In order to keep it in the repository I added a define asvversion, which has to MANUALLY be set, if one wants to use that class. The changes are in principle ease, one has to check the interface to the tracker classes and the positions are indicated by the defines.
 181
 182 2003-11-13  Anders Strand Vestbo  <vestbo@hansa00>
 183
 184         * /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
 185         Added additional data written to file
 186
 187         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h:
 188         Added some additional data members and storage
 189
 190 2003-11-12  Anders Strand Vestbo  <vestbo@hansa00>
 191
 192         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.h:
 193         Main changes:
 194         - New function LocalLocalSegments, for local (patch-like) tracks segments.
 195         - Some changes in search ranges and fit ranges.
 196
 197 2003-09-18  Constantin Loizides  <loizides@hansa00>
 198
 199         * /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx:
 200         Commented compile breaking due to aliroot changes.
 201
 202 2003-08-22  Anders Strand Vestbo  <vestbo@hansa00>
 203
 204         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModels.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx:
 205         - Removed field fNClusters from AliHLTTrackModel. The reason is the new scheme
 206         were the number of clusters is _not_ written for every track. Instead, we assume
 207         a potential number of clusters which is equal to the number of padrows in the
 208         patch/slice (this number then needs not to written). Then we denote whether a
 209         cluster is present or not by writing 1 bit for every padrow.
 210         - The residual quantization (stored in AliHLTDataCompressor) is now specified
 211         for the three different pad sizes.
 212
 213         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompLinkDef.h, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTOfflineDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/Makefile:
 214         Splitted handling of offline-data compression and HLT-data compression.
 215         For offline-data input the new class AliHLTOfflineDataCompressor is used.
 216         This class is a child of AliHLTDataCompressor, and has the exact same interface.

 248         * /alice/cvs/hltcvs/level3code/comp/AliHLTFitUtilities.h, /alice/cvs/hltcvs/level3code/comp/bitio.h:
 249         Added extern "C" decleration of the C functions which are used in C++ classes.
 250         This was obviously not strictly necessary in some compilers later than 2.95,
 251         but when compiling with 2.95 I was not able to link anymore. And it also
 252         _should_ be defined like this of course. Since the files are also processed
 253         by C compiler, a check has to be done in order only to use the extern "C" flags
 254         when compiling in C++, as the C compiler does not now this flag.

 257
 258         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx:
 259         Added gccversion check.

 262
 263         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h:
 264         Changed pointer to input data from AliHLTMemHandler to AliHLTSpacePointData.
 265         In addition a array of int holding the number of clusters in each
 266         subsector is provided. Same thing as being done in e.g. AliHLTFitter.
 267         Added option to process on patch-level for various reason. This option
 268         is controlled by the flag fSinglePatch set in LoadData, and should only
 269         be used with care, since there are some functions which expects whole
 270         slices; these have to be changed when running fSinglePatch=0.
 271
 272         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h:
 273         Forgot this one last time
 274
 275         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx:
 276         Cosmetic changes only
 277
 278         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx:
 279         Changed the return of most functions ot boolean, in order to perform
 280         external checks when things are not working.
 281         Also changed the comparison of original data to those of 8 bit data, and
 282         not 10bit.

 284 2003-06-04  Anders Strand Vestbo  <vestbo@hansa00>
 285
 286         * /alice/cvs/hltcvs/level3code/comp/AliHLTFitUtilities.c:
 287         Stop writing error messages all the time
 288
 289         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx:
 290         - Fixed a memory leakage problem in FitClusters.
 291         - In LoadSeeds, enable the possibility of track extending over 3
 292         sectors.

 297         Minor updates connected to last checkin.
 298
 299         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.h, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
 300         Stable version again. Taking offline tracks as input for cluster fitting seem
 301         to work now. However, when finding and fitting clusters this way, and using
 302         these clusters as input for compression, the final offline tracking
 303         efficiency drops a few percent compared to the original. The source of this
 304         drop seems to be that the residuals in the outer padrows are too large
 305         for the cluster fitting algorithm to locate the cluster based on the
 306         calculated track crossing with padrow.

 309
 310         * /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTClusterFitter.h:
 311         Bugfix. In CheckCluster one has to check whether a fit attempt
 312         has been done by track->IsSet(row). This was earlier done in FitClusters,
 313         but this produced some memory leakage.

 323         Changes:
 324         - AliHLTClusterFitter/AliHLTModelTrack :
 325           One bit in AliHLTClusterModel::fPresent is reserved for fit attempt
 326         - Enable multiple event handling in AliHLTDataCompressor
 327
 328         * /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTDataCompressor.h:
 329         Added function LoadOfflineData, which allows to use offline
 330         reconstruced tracks as input for the compression.

 335         Mostly cleaning up and making nicer code. Some changes in AliHLTClusterFitter:
 336         -WriteClusters has been moved from AliHLTModeller.
 337         -Implementation of seeds coming from tracking in outer padrows.

 342         New version of compression classes. The main changes are:
 343         - AliHLTDataCompressor has been completely rewritten. Instead of
 344         storing remaining digits, the remaining clusters are stored. Also,
 345         the remaining clusters which are stored can be cleaned,
 346         meaning that one only stores clusters which are on certain padrows.
 347         In particular one stores everything which is on
 348         padrows used for seeding in offline.
 349         - New data structures for remaining clusters in AliHLTModels.h
 350         - Some bugfixes in AliHLTModelTrack. In CalculateClusterWidths,
 351         one can specify a flag to parametrize cluster errors from
 352         the cluster widths.

 355
 356         * /alice/cvs/hltcvs/level3code/comp/AliHLTModels.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx:
 357         Removed cluster charge field from the AliHLTTrackModel, since it is
 358         not used anyhow. Some fixes in AliHLTModelTrack, most important one
 359         a bug in destructor where not everything was deleted.

 369         Checking in all changes which gas been done the latest month.
 370         Basically a lot of rewrites, specially in the cluster fitter class.
 371         All code was tagged before this checkin.

 386         More or less working version now. Everything is handled in the
 387         AliHLTDataCompressor class. Remaining digits are written to rootfile
 388         and processed by the offline cluster finder. In AliHLTModeller::CheckCluster
 389         it is also checked how big/small the cluster is in order not to save
 390         overlapping/noise clusters.

 395         New interface class for the compression classes.
 396         Contains all the functions needed to do the different
 397         steps; modelling - compressing - uncompressing - running offline etc.

 401         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h:
 402         Changed parameters of WriteRootFile
 403

 405
 406         * /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.h:
 407         Added new function AliHLTModeller::CheckCluster. Function checks if the
 408         cluster corresponding to a certain track crossing point is a good cluster;
 409         if it is isolated and only 1 peak. If not, cluster is saved as remaining
 410         digits.

 414         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
 415         Can print compression ratio to file in AliHLTCompress::PrintCompRatio.
 416         Minor changes to AliHLTModeller; differ between fTimeOverlap (pad)
 417         and fTimeSearch (newly added boolean). The latter is used when searhcing
 418         for a cluster around the track crossing point, while the first is only
 419         used when checking for overlaps.
 420

 422
 423         * /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTCompress.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModeller.h, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.cxx, /alice/cvs/hltcvs/level3code/comp/AliHLTModelTrack.h:
 424         Some changes resulting from last week work. The mc stuff has been removed.
 425         Added possibility to not save the width when compressing file; this is one
 426         by setting the flag AliHLTCompress::fWriteShape.
 427
 428         The status of the code is that it seems to be more or less working. The
 429         efficiency drops a little bit when running it through offline, but this
 430         is mainly because overlapping clusters are not deconvoluted, and 2 clusters
 431         found by the offline cluster finder will be 1 cluster after compressing/
 432         decompressing. The only way to get rid of this, is to include some
 433         deconvolution in the AliHLTModeller::FindClusters.

 448         Added possibility to compile and run with mc information. This was done
 449         by adding a new data member to AliHLTClusterModel (in AliHLTModels.h), and
 450         a function AliHLTModeller::GetTrackID.

 478         Moving to static AliHLTTransform.
 479         Some changes has been made since last checkin;
 480         some smaller bugfixes everywhere. The number of pads in a cluster is stored,
 481         because there are some cluster containing only 1 pad which create problems
 482         when restoring the data. In principle one has to remove these clusters
 483         before writing them, but this has not been incorporated yet.
