title: 3 TeV jgun collisions, Single jet type, JET GUN generator: jgun_jet_single_pt3tev

description: Single jet gun for detector studies: The events contain a single jets from all QCD processes at 14 TeV pp collisions. Events were simulated using the Pythia8 A2 pp tune for 14 TeV. Jets were reconstructed using the anti-kT fastjet algorithm with R=0.4 and pT above 3 TeV (all eta). Then only one jet per event was taken. All particles that fall outside the cone 0.1 around the jet center were removed. The sample with jet cores is designed for detector performance studies to reduce simulation step.

title: Software Coding and Compiling Techniques for Energy and Power Aware Computing

description: The combination of the compiler and coding style plays an important role in the application’s performance, power, and energy consumption. This study provides a recommendation system for achieving efficient energy consumption. It demonstrates - via experimentation - that to achieve a balance between the performance, power, and energy consumption, the combination of compiler and coding style should be deviced in a way that works best for the target-machine architecture and the system constraints. The study performed experimentation on four different compilers and three selected coding styles, with an in-depth analysis of the two compilers with the most different results, showing how different coding practices could produce different performance and energy consumption for the same problem, along with the compiler selection that affects not only the application's performance but also the energy consumption. The study also elaborates on why the different compilers and styles are generating significant differences in performance and power measurements. Validation of the research findings was performed on SQLite3, a popular open source application, resulting 19.28% power reduction, 9.52% energy reduction, and 14.22% decrease in execution time.
