چکیده
We report the status of CMS full simulation for Run 3. During long shutdown LHC a significant update has been introduced to code simulation. The geometry description is reviewed. Several important modifications were needed. detector software migrated DD4Hep community developed tool. will on our experience obtained during process this migration. Geant4 10.7 choice 3 productions. discuss arguments choice, strategy adaptation new version, and physics performance A special Physics List configuration FTFP_BERT_EMM be described, which provides compromise between accuracy CPU performance. fraction time events spent tracking charged particles in magnetic field. In dynamic parameters field implemented. method into electromagnetic components hadronic showers calorimeter CMS. For low-energy electrons positrons parametrization GFlash type applied. Results tests discussed. summary, we expect about 25% speedup production compared 2 simulations.

CMS software and computing for LHC Run 2
The CMS offline software and computing system has successfully met the challenge of LHC Run 2. In this presentation, we will discuss how the entire system was improved in anticipation of increased trigger output rate, increased rate of pileup interactions and the evolution of computing technology. The primary goals behind these changes was to increase the flexibility of computing facilities whe...
متن کاملRun Control and Monitor System for the CMS Experiment
The Data Acquisition (DAQ) of the CMS Experiment [1] is composed by O(10000) network objects spread in O(1000) nodes, most of them based on commodity PCs, connected to a very efficient Local Area Network. The DAQ complex (both hardware and software) must be controlled in order to synchronize all the objects to perform in the proper sequence the needed actions: configure the experiment, start, s...
متن کاملA Full-Cycle 3 Dimensional Numerical Simulation of a Direct Injection Diesel Engine
In the present work, multidimensional modeling of open-cycle process of OM355 engine was developed. Calculations for computational mesh were carried out. The results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. Results included pressure, temperature, emissi...
متن کاملPlanning Simulation Run Length for Queueing Systems
Simulation of large scale networks can be very time and resource-consuming. It is hard to predict when the amount of data collected from a simulation is enough and the measurement is accurate enough for the parameter of interest. In this paper, we study the planning of simulation run length, and investigate how many cycles of overflow / non-overflow are needed for the packet loss probability to...
متن کاملReadiness of CMS Simulation towards LHC Startup
CMS experiment has used detector simulation software in its conceptual as well as technical design. With the detector construction near its completion, the role of simulation has changed toward understanding collision data to be collected by CMS in near future. CMS simulation software is becoming a data driven, realistic and accurate Monte Carlo programme. The software architecture is described...
