Given the constantly growing complexity of multi-core architectures, Design Space Exploration (DSE) tools play an important role to evaluate different design options. In this paper, we present a DSE toolset targeting massively parallelized HW/SW architectures with a high degree of flexibility in order to successfully simulate multi-core-multi-node platforms. Our DSE tools provide a rapid and simple-to-use work-flow to easily retrieve and analyze the key metrics and eventually evaluate the design. We examine the DSE toolset and methodology while performing several simulations of a general purpose 1K-core architecture and evaluate not only standard metrics like the L2 cache miss rates, but also operating system activity and its impact. We leverage the knowledge gained in our methodology to develop and evaluate a novel dataflow execution model named “DataFlow-Threads” (DF-Threads). We validated the outcomes of the simulator against an equivalent FPGA-based design.
