# Simulation Turnaround Time

*/Metrics/Simulation_Turnaround_Time*

## Overview

Simulation Turnaround Time measures the exact duration from launching a computational model to extracting a definitive test result. It encompasses code compilation, environment setup, workload partitioning across compute clusters, and log aggregation. Hardware and system engineers track this metric to quantify design velocity in environments where a single run spans several hours.

The underlying workflow relies on brittle, manual configurations that artificially inflate the turnaround time. Engineers allocate nodes, configure job schedulers, and manage complex library dependencies by hand. Simulations routinely fail hours into a compute cycle due to trivial setup errors, forcing engineers to parse massive text logs, adjust parameters, and restart the entire process.

This workflow is highly fertile ground for autonomous agents and headless services. AI agents monitor active compute jobs to detect early failure patterns, preemptively halting doomed runs to free up cluster resources. Services-as-software platforms ingest raw design files, handle all infrastructure provisioning, execute the simulation, and return isolated root-cause failure data directly to the engineer.
