Gundam v1.4.3

What's new?

• Attempt to fix random segfault occuring on CCLyon
• Adding selectionCutFormula option in dataset definition
• Now showing CPU efficiency while fitting
• Adding the option "-a" to force loading asimov in data container (regardless of selectedDataEntry and selectedToyEntry)
• Fixing memory leaks spoted by valgrind

Full changelog of 1.4.2-> 1.4.3

Gundam v1.4.2

What's new?

• Not throwing free parameters
• Minor improvements

Full changelog of 1.4.1-> 1.4.2

Gundam v1.4.1

What's new?

• Increase breakdown stat output
• gundamFitter now handles -s for specifying a given seed while using gRandom
• Now xsllhFitter apps and libs aren't built along with GUNDAM sources. One can trigger back the building using cmake option -D WITH_XSLLHFITTER=ON
• Added proper option -D USE_STATIC_LINKS=ON to enable static link
• Added doxygen build setup: add -D BUILD_DOC=ON to cmake and then make doxygen
• Dropping version number in built libs

Bug fixes

• Fixed mirror dials
• Fixed bug while locking threads in SplineDial evaluation
• Fixed possible bug while indexing binned dial

Optimizations

• Optimized CPU parameter propagation (using embedded for_each)
• Using memory proximity data (RAM access is not parallelized)
• Lighter event loading
• Using DialWrapper to properly handle unique_ptr
• Various fixes/improvements in the toolbox

Full changelog of 1.4.0-> 1.4.1

Gundam v1.4.0

What's new?

• Dataset definition now extended (proper support for Data, Fake-data, Toy-MC) with override options for custom variable definition
• Throwing statistical uncertainties on pseudo-data when using --toy option
• Adding support for custom toys definition using --toy N, where is the toy index. This is providing a selected index that is used to select a given variable array index while reading the input TTrees.
• Lower RAM needed to load dials
• Adding CUDA support for GPU extension!!
• Adding dockerfile
• Adding gundamFitCompare which compares 2 output files from gundamFitter

Full changelog of 1.3.5-> 1.4.0

Config fileset for T2K OA2020-like (not including inputs)

GUNDAM is comming to the Nintendo Switch!! 😉 (demonstrating the GPU capabilities!)

Gundam v1.3.5

What's new?

• Fixing YAML cpp lib link when using the custom made .cmake find package script
• The option -D COLOR_OUTPUT=OFF can be set in the cmake config to disable any colored output.
• Using proper mutex for the spline eval
• Generalizing minimumSplineResponse to minDialResponse and maxDialResponse
• Extending the definition of applyCondition to a list definition under applyConditions which can be set with different syntax
• Fixing error evaluation in sample bins
• Introducing custom LLH BarlowLLH_OA2020_Bad which reproduces the bug from the OA2020 in BANFF

Full changelog of 1.3.4-> 1.3.5

Gundam v1.3.4

What's new?

• Adding gundamConfigCompare which scans 2 config files and highlight the differences
• Added the cmake/gundam-setup.sh env script which provide an easy interface for compilation
• Overall reshape of the CMakeList config files
• Showing IO read speed while loading the event to RAM
• Dial is now a pure virtual class
• Generalizing minSplineResponse to minDialResponse and maxDialResponse
• Rescaling plot frames wrt legend size
• Prefit/postfit comparison plot also generated on a normalized scale (free parameters are rescaled wrt the provided step/stdDev if available)

Full changelog of 1.3.3-> 1.3.4

Preview of the new app gundamConfigCompare:

Gundam v1.3.3

• Add mirror dial option
• Adding gundamPlotExtractor

Full changelog of 1.3.2-> 1.3.3

Example for using the new feature mirror dial in the parameter definition config:

- parameterName: "parameterName"
  isEnabled: true
  dialSetDefinitions:
    - dialsType: Spline
      applyOnDataSets: [ "DetectorName" ]
      dialLeafName: "dialLeafName"
      useMirrorDial: true
      mirrorLowEdge: -1.
      mirrorHighEdge: 1.

Gundam v1.3.2

• Add template parameter definition (possibility to define free parameters without a covariance matrix)

Full changelog of 1.3.1-> 1.3.2

Config example attached bellow. To run the example, unzip and launch:

gundamFitter -c Fitter.yaml -t 6

Gundam v1.3.1

• Table printouts

Full changelog of 1.3.0-> 1.3.1

Gundam v1.3.0

• Added option to set flat prior on specific parameters
• Covariance matrices are now stripped (removing fixed parameter) before inversion
• Minimizer now only handles non fixed parameters (reduce the Hessian dimensionality)

Full changelog of 1.2.8 -> 1.3.0
