Many community SST developers maintain additional element libraries and tools. We've collected a list of them here.

Element Libraries


BE-SST is a coarse-grained parallel discrete-event simulator, developed at the PSAAP II Center for Compressible Multiphase Turbulence at the University of Florida, used for system-level modeling and simulation of existing and notional HPC systems.


The Rev SST component is designed to provide cycle-based simulation capabilities of an arbitrary RISC-V core or cores.


STONNE is a cycle-level microarchitectural simulator for flexible DNN inference accelerators. STONNE models all the major components required to build next-generation flexible DNN accelerators like MAERI or SIGMA. All the on-chip components are interconnected by using a three-tier network fabric composed of a Distribution Network(DN), a Multiplier Network (MN), and a Reduce Network(RN), inspired by the taxonomy of on-chip communication flows within DNN accelerators. STONNE has been integrated as a component called sstStonne in SST. sstStonne connects to memHierarchy component to faithfully model the memory hierarchy of the accelerator. The STONNE-MemHierarchy integration allows to run four main operations: CONVOLUTION, GEMM (Dense matrix multiplication), sparse-sparse GEMM operation where the matrices are encoded using a bitmat format, and sparse-dense matrix multiplication (spMM) where the sparse matrix in encoded in CSR format. The simulator is configurable to support different architectural parameters and different memory hiearchy organizations. Basic installation/usage instructions can be found in the additional external elements section of the current SST release documentation.
