Interpretation : The GPU backâend yields consistent 2.3â2.7Ă reductions in wallâclock time. Even on CPUâonly systems, the refactored kernels provide ~30 % speedâup over v6.9. Peak memory usage remained below 8 GB for all cases, well within the 16 GB limit of the test laptops. The GPU version showed a modest increase (â + 0.5 GB) due to device memory allocation. 6.3.

email@university.edu Abstract QCFire is an openâsource, physicsâbased wildfire spread model that has been widely adopted for research, planning, and operational forecasting. The latest release, UMâT QCFire 7.3 , introduces a suite of performanceâoptimised kernels, an expanded atmospheric coupling interface, and a userâfriendly graphical installer. This paper presents a comprehensive overview of QCFire 7.3, details the stepâbyâstep download and installation workflow across Windows, macOS, and Linux platforms, and evaluates the modelâs computational efficiency and predictive accuracy on three benchmark scenarios (grassland, mixedâfuel forest, and urbanâwildland interface). Results demonstrate up to 45 % reduction in runtime relative to version 6.9 while maintaining or improving agreement with field observations (RMSE = 0.12 m·minâ»Âč). The manuscript concludes with recommendations for best practices in deployment and outlines future development pathways. 1. Introduction Wildfire modelling has become a cornerstone of risk mitigation and emergency response. Among the many tools available, QCFire distinguishes itself by coupling quasiâsteady fireâline dynamics with a highâresolution atmospheric solver, enabling realistic simulation of plumeâdriven spread (Finney 2004; Mandel et al. 2011). The GPU version showed a modest increase (â + 0
Version 7.3, released by the University of Michiganâs Computational Fire Science (UMâT) group in March 2026, marks a major milestone: the codebase has been refactored for , the input schema has been modernised to JSONâbased configuration , and a crossâplatform installer (UMâT QCFireâInstaller 7.3) simplifies acquisition for nonâtechnical users.
