Halve the Inner Solver in a Crash-Simulation Pipeline

FreeVerified credential2 weeksAdvanced

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.
