In this paper, the authors present the design of a novel multicore simulator called ParTejas. It is a fast shared memory based parallel simulator written in Java. Unlike recently released parallel simulators that mainly rely on sampling, high level models, and highly relaxed synchronization, they primarily rely on novel concurrent data structures. In specific, they use a lock free parallel slot scheduler for synchronizing the accesses of multiple threads at a shared resource, and they use flexible barriers known as phasers to relax synchronization within bounds.
