o global, modular, flexible o reuse calculation elements to the maximum permissible extent o model database: SM, SUSY, nucl., astro-, cosmo- & beyond! o comprehensive observable (data+likelihood) libraries o general, fast definition of new models and datasets o plug&play observable, likelihood calculators, scanners o various statistical options: Bayesian, frequentist, sampling o mixed mode (MPI+openMP), multi-level, mostly automated parallelization on a laptop or on a supercomputer o open-source, maintained, developed code
C Balázs | DSU 2016 Jul 28 Bergen | page 14 of 23 GAMBIT modularity No more hard coded interfacing!
o auto downloading, configuring, compiling backends (cmake) o dynamic loading of C++ classes from backends (BOSS) o automatic dependency resolution for run-time plug&play o mix and match backend selection o generic container objects o diskless exchange of Les Houches Accord information o flexible output streams: ASCII, HDF5, databases, … o all-in or module standalone modes o POSIX signal handling for safe early shutdown/resume o seamless integration of new calculations as they become available (minimize “hacking” of backend)

GAMBIT is like a conductor: assembling musicians into a coherent orchestra.
So far you wrote songs for individual instruments.
With GAMBIT you can start composing symphonies.
We are very happy to talk to prospective users! GAMBITers at DSU to talk to: T. Bringmann, T. Gonzalo, A. Kvellestad, A. Raklev, C. Weniger
C Balázs | DSU 2016 Jul 28 Bergen | page 23 of 23 Fox still has the X-Men spin-off GAMBIT penciled in for an October 2016 release, but I wouldn’t count on it staying that way. An early 2017 release seems more likely at this time, perhaps even in February ala Deadpool this year. .
