Overview
What this challenge is about.
Benchmark four solver-preconditioner combos on crash-simulation matrices, run a strong-scaling sweep, and earn a verifiable certificate.
The scenario
The supplier validates crash-structure designs virtually before any physical prototype, so simulation turnaround time directly gates how many design variants the engineering team can evaluate before a manufacturer deadline. The inner sparse linear solve dominates that turnaround, making solver choice a first-order engineering and cost decision.
The Brief
What you'll do, and what you'll demonstrate.
Find a Krylov-solver-plus-preconditioner combination that roughly halves the inner sparse-solve wall time of a finite-element crash simulation while staying robust across mesh sizes.
Earning criteria — what you'll demonstrate
- Select and configure Krylov iterative solvers and preconditioners appropriate to large sparse structural systems.
- Tune incomplete-LU and algebraic-multigrid preconditioners deliberately and explain the parameter trade-offs.
- Measure strong-scaling efficiency from 1 to 64 cores and identify the point where added cores stop paying off.
- Design a benchmark harness whose results are reproducible across reruns and machines.
- Translate benchmark evidence into a defensible, actionable engineering recommendation.
