Common use of Simulation Environment Clause in Contracts

Simulation Environment. Our simulation framework is a combination of tools chosen to simulate a CMP system as closely as possible. In Figure 2, we present an overview of the simulation environment. Multi2sim [15] is a simulation framework for heterogeneous computing, including models for superscalar, multi- threaded, multicore, and graphics processors. It allows one or more applications to run on top of it without booting a guest operating system, and implements emulation of system calls and x86 instructions. Multi2sim implements contexts which define how an application behaves. It is able to model a complete memory hierarchy system integrated into the CMP and its connection to the respective processor cores. Although Multi2sim allows for defining basic interconnection networks (bus and basic point-to-point), we opted to combine Multi2sim with an in-house cycle-accurate flit-level network-on-chip simulator called gNoCsim (developed by Universidad Polit´ecnica de Va- lencia, and being used in the NaNoC project [11] by different partners). gNoCsim is able to simulate the communication and more complex topologies for all the resources in the chip; caches, memory controllers, and processor cores. With this simulator, different configurations of routing strategies, arbitration control, and packet switching policies can be defined, as well as other switch properties like buffering strategies et cetera.
