Description
The objective of this project is to exploit the capabilities offered by the multicore architecture to improve the performance of the socio-demographic dynamics simulator, Yades (Yet Another DEmographic Simulator), created at InLab in collaboration with the Lancaster University and the Barcelona Super Computing Center (BSC).
To achieve this goal, the ROOT-Sim library (ROme OpTimistic Simulator) has been used to take advantage of the benefits offered by a shared memory architecture to optimize the performance of the simulator. This improvement makes it possible to reduce intra-node communications and to provide the simulator with more advanced capabilities to work with a currently highly extended architecture.
To achieve this, a collaboration with the High Performance and Dependable Computing Systems Group (DIAG) of the University of Sapienza was initiated in order to adapt our simulator with its ROOT-Sim library, a general purpose, parallel discrete event simulation (PDES- Parallel Discrete Event Simulation) library. This static library can be used with any model that follows the ANSI-C standard.
This project has not only optimized the performance of the Yades simulator in multicore architecture but has also contributed to the development of some parts of the ROOT-Sim library and its testing with a real application model.
