Randomized trial shows improved performance in numerical simulations using a plugin-based framework, implying enhanced engineering capabilities.

Key Points

The study aims to introduce TopSim, a C++ framework designed for numerical simulations in parallel environments, enhancing code extensibility and performance.
Developed an extensible framework leveraging a plugin architecture for runtime configurability.
Implemented integrated data structures for topology representation and communication among plugins.
Evaluated performance through mechanics-oriented benchmarks and distributed scaling experiments.
TopSim’s distributed linear algebra algorithms showed lower elapsed times compared to PETSc in most configurations tested.
The performance improved for configurations with workloads over 10K elements per core, enhancing efficiency.
While TopSim exhibited weaker strong scaling, it consistently demonstrated better weak scaling than the PETSc configuration.
