Abstract: SimK is a parallel discrete event simulation engine developed by state key laboratory of computer architecture in institute of computing technology, Chinese academy of sciences. Based on the released SimK-1.0, we extended the function of task partition and the blocking controlling in the process of synchronization. We released version 1.1 of SimK. On the other hand,as it lacks a benchmark to specifically SimK simulation performance and there is no comprehensive evaluation data,we first proposed the rules of development Benchmark for parallel simulation engine. Then we introduced the example "PassBa11". We used it to do the evaluation of SimK on the weak and strong scalability, as well as the strong scalability in unbalanced workload condition. Then we compared the speed-up ratio between the balanced workload and unbalanced workload condition in strong scalability test. The influence of simulated computing workload on speed-up ration from was also explored. We also discussed the applicability of the Benchmark. It can be concluded from our experiments as follows;a)our example "PassI3a11" is available to be the benchmark for SimK,as well as other parallel simulation engine. b) SimK has favorable strong and weak scalability. c) Both the load balance and the simulated computing workload will have effect on the speed-up ratio.
