Interpretation : The GPU back‑end yields consistent 2.3–2.7× reductions in wall‑clock time. Even on CPU‑only systems, the refactored kernels provide ~30 % speed‑up 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 (≈ + 0.5 GB) due to device memory allocation. 6.3.

email@university.edu Abstract QCFire is an open‑source, physics‑based wildfire spread model that has been widely adopted for research, planning, and operational forecasting. The latest release, UM‑T QCFire 7.3 , introduces a suite of performance‑optimised kernels, an expanded atmospheric coupling interface, and a user‑friendly graphical installer. This paper presents a comprehensive overview of QCFire 7.3, details the step‑by‑step download and installation workflow across Windows, macOS, and Linux platforms, and evaluates the model’s computational efficiency and predictive accuracy on three benchmark scenarios (grassland, mixed‑fuel forest, and urban‑wildland 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·min⁻¹). 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 quasi‑steady fire‑line dynamics with a high‑resolution atmospheric solver, enabling realistic simulation of plume‑driven spread (Finney 2004; Mandel et al. 2011). umt qcfire 7.3 download
