source software package to replace a variety of existing codes. The
modular integrated software framework will consist of interacting
generators to simulate (i) wave functions of the incoming nuclei, (ii)
viscous fluid dynamical evolution of the hot plasma, and (iii) transport
and modification of jets in the plasma. Integrated advanced statistical
analysis tools will provide non-expert users with quantitative methods
to validate novel theoretical descriptions of jet modification, by
comparison with the complete set of current experimental data. To
improve the efficiency of this computationally intensive task, the
collaboration will develop trainable emulators that can accurately
predict experimental observables by interpolation between full model
runs, and employ accelerators such as Graphics Processing Units (GPUs)
for both the fluid dynamical simulations and the modification of jets.
The collaboration will create this framework with a user-friendly
envelope that allows for continuous modifications, updates and
improvements of each of its components. The effort will serve as a
template for other fields that involve complex dynamical modeling and
comparison with large data sets. It will open a new era for
high-precision extraction of the internal structure of the Quark-Gluon
Plasma with quantifiable uncertainties.
