One of the objectives of the decade for High-Performance Computing systems is to reach the exascale level of computing power before 2018, hence this will require strong efforts in their design. In that sense, High-speed low-latency interconnection networks are essential elements for exascale HPC systems. Indeed, the performance of the whole system depends on that of the interconnection network. In order to develop and test new techniques, suited to exascale HPC systems, software-based networks simulators are commonly used. As developing a network simulator from scratch is a difficult task, several platforms help the developers, OMNeT++ being one of the most popular. In this paper, we propose a new generic network simulator, exploiting the features of the OMNeT++ framework. The proposed tool is the first step to model HPC high-performance interconnection networks of exascale HPC systems: the message switching layer, routing and arbitration algorithms and buffer organizations have been modeled according to the current and expected characteristics of these systems. In addition, the tool has been designed so that it is possible to simulate networks of large size. Simulation results, validated against real systems, show the accuracy of the model. |
