ESPResSo is an open-source molecular dynamics package for simulating and analysing coarse-grained soft-matter systems. It supports research on polymers, liquid crystals, colloids, ferrofluids, and biological materials such as DNA and lipid membranes.

McPAT is an architectural modeling tool for chip multiprocessors (CMP). The main focus of McPAT is accurate power and area modeling, and a target clock rate is used as a design constraint. McPAT performs automatic extensive search to find optimal designs that satisfy the target clock frequency.

FireSim is an open-source FPGA-accelerated full-system hardware simulation platform that makes it easy to validate, profile, and debug RTL hardware implementations at 10s to 100s of MHz.

GPGPU-Sim is a cycle-level simulator modeling contemporary graphics processing units (GPUs) running GPU computing workloads written in CUDA or OpenCL.

SimCXL is a full-system, cycle-level simulator based on gem5 that provides complete support for all three CXL sub-protocols and all three types of CXL devices.

The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture. It is primarily used to evaluate new hardware designs, system software changes, and compile-time and run-time system optimizations.
