Optimizing Vulkan Dispatch Schedules for Real-Time U-Net Denoising

We present a light-weight and portable ONNX to Vulkan conversion framework that is designed for efficient, fully GPU-resident deployment of U-Net-based networks. The post Optimizing Vulkan Dispatch Schedules for Real-Time U-Net Denoising appeared first on Lucas Alber .

HPG Student Competition 2025: Percentile-based Adaptive SVGF

We describe the algorithm currently used to denoise our Quake path-tracing demo, Merian-Quake, which won first place at the 2025 High-Performance Graphics (HPG) Student Competition. The post HPG Student Competition 2025: Percentile-based Adaptive SVGF appeared first on Lucas Alber .

Real-Time Markov Chain Path Guiding for Global Illumination and Single Scattering

We present a lightweight and unbiased path guiding algorithm tailored for real-time applications with highly dynamic content. The algorithm demonstrates effectiveness in guiding both direct and indirect illumination. Moreover, it can be extended to guide single scattering events in participating media. The post Real-Time Markov Chain Path Guiding for Global Illumination and Single Scattering…

Traveler’s Guide to Colombia

Navigating this beautiful country was a bit tricky at times. For this reason I made some notes during my travel which I'll drop here. The post Traveler s Guide to Colombia appeared first on Lucas Alber .

Continuing to Catch Up with State of the Art Continuous Integration Pipelines in Palladio–The Experience Report Strikes Back

This research paper presents a case study on the migration from Jenkins to GitHub Actions for automated builds in the development workflow for Palladio.

[QuickTipp] Renew an expired GnuPG subkey

It s that time of the year again Let s renew our subkeys! Checking for an expired subkey GPGs messages are not that clear when a subkey expires. For example, Git may refuse to sign a commit with the cryptic message gpg failed to sign the data. Or the journal logs a [ ] The post [QuickTipp] Renew an expired GnuPG subkey appeared first on Lucas Alber .

Cost-aware Adaptive Sampling for Global Metamodeling Using Voronoi Tessellation

We introduce a novel Voronoi-based cost-aware adaptive sampling algorithm for global metamodeling that is independent of the choice of sampling strategy and metamodel. The method is evaluated on a variety of randomly generated black-box and cost functions, where it has shown to vastly outperform existing sampling strategies. The post Cost-aware Adaptive Sampling for Global Metamodeling Using…

KeyHelp – Der Schlüssel zum entspannten Webhosting

Webhosting mal ganz entspannt! Das verspricht das Control Panel mit schnell wachsendem Funktionsumfang und schicker Oberfläche. Kommandozeilen-Kung-Fu und Skriptmagie soll nun der Vergangenheit angehören. Im Gegensatz zu den etablierten Alternativen cPanel und Plesk gibt es KeyHelp sogar kostenlos. Zumindest wenn man auf Dark Mode, SSH-Chroot und 1-Click-Installer verzichten kann. Die [ ] The post…

Beautiful Plots with Matplotlib and LaTex

Stop resizing, cropping and pixelated plots. Matplotlib integrates very well with LaTex — if configured correctly. The post Beautiful Plots with Matplotlib and LaTex appeared first on Lucas Alber .

PHP-fpm unter Apache2 aktualisieren

Es ist mal wieder so weit, die aktuelle PHP-Version läuft aus und eine Aktualisierung von PHP steht an, um die neusten Sicherheitsupdates zu erhalten. Der Beitrag stellt die Vorgehensweise PHP-fpm unter Apache2 zu aktualisieren nur beispielsweise am Upgrade von 7.2 zu 7.4 dar, lässt sich aber für die meisten anderen [ ] The post PHP-fpm unter Apache2 aktualisieren appeared first on Lucas Alber .
