Title: GeantV alpha release

Abstract

In the fall 2016, GeantV went through a thorough community evaluation of the project status and of its strategy for sharing the R&D results with the LHC experiments and with the HEP simulation community in general. Following this discussion, GeantV has engaged onto an ambitious 2-year road-path aiming to deliver a beta version that has most of the final design and several performance features of the final product, partially integrated with some of the experiment’s frameworks. The initial GeantV prototype has been updated to a vector-aware concurrent framework, which is able to deliver high-density floating-point computations for most of the performance-critical components such as propagation in field and physics models. Electromagnetic physics models were adapted for the specific GeantV requirements, aiming for the full demonstration of shower physics performance in the alpha release at the end of 2017. We have revisited and formalized GeantV user interfaces and helper protocols, allowing to: connect to user code, provide recipes to access efficiently MC truth and generate user data in a concurrent environment.

Figure 1 Figure 1: The GeantV stepping procedure decomposed in stages. Each stage loops over input tracks, selecting among a set of models corresponding to the stage. Tracks may be either “basketized” with others and sent to vectorized algorithms, or processed by the selected model in scalar mode. This approach improves themore » locality and cache coherency compared to the classical stack-based approach.« less
