Efficient process interaction with threads in parallel discrete event simulation

Parallel discrete event simulation (PDES) decreases a simulation´s runtime by splitting the simulation´s work between multiple processors. Many users avoid PDES because it is difficult to specify a large and complicated model using existing PDES tools. In this paper we describe how the PARASOL PDES system uses migrating user level threads to support the process interaction world view. The process interaction world view is popular in sequential simulation languages and is a major departure from the logical process view supported by most PDES systems
