Model. Pract. Theory 17, No. 5, 850-870 (2009).} \itemab Summary: Technological improvements in the use of computers through the better management of multithreading, such as with multi-core computers (core duo, core 2 duo, core 2 quad), have resulted in a reassessment of systems for simulating discrete events which can exploit these new capabilities. We consider the design and implementation of a process-oriented discrete event simulation library which makes exhaustive use of concurrence to improve the efficiency with which the simulations are executed. \itemrv{~} \itemcc{} \itemut{discrete event simulation; concurrency; process-oriented} \itemli{doi:10.1016/j.simpat.2009.02.006} \end
