Research & Development. Designed, developed, and analyzed the performance of "HydraNetSim" - a discrete event simulator which allows parallel simulation by exploiting the capabilities of parallelization of modern multicore computing hardware. It is based on a manager-worker paradigm. It divides the simulation model into a number of specific workers (a cluster of processes) considering the number of cores provided by the underlying computing hardware.

Designed, developed, and analyzed the performance of "HydraNetSim" - a discrete event simulator which allows parallel simulation by exploiting the capabilities of parallelization of modern multicore computing hardware. It is based on a manager-worker paradigm. It divides the simulation model into a number of specific workers (a cluster of processes) considering the number of cores provided by the underlying computing hardware. The synchronization between the workers is done via (proposing and implementing) a novel variant of classic null-message algorithm to keep the overhead as low as possible. Show less
