Previously, he worked as software engineer among physicists at CERN on real-time and embedded software for the Large Hadron Collider, as well as data layout abstractions for heterogeneous architectures, for which he received a PhD in High Performance Computing from the University of Dresden, Germany. Before, he implemented GPU accelerated simulations and 3D visualizations of industrial machining processes. Since 2022, Bernhard is a voting member of WG21 and his interests span geometry, 3D visualizations, optimization, SIMD, GPU computing, refactoring and teaching C++.Koen is an engineer specializing in high-quality software with a strong mathematical foundation. With a PhD in Computer Science from KU Leuven, his work bridges applied mathematics and performance-critical software engineering. As Team Lead for HMI Software at NV Michel Van de Wiele, he focuses on developing C++/Qt applications for textile production systems, optimizing performance, usability, and cloud integration. Passionate about elegant, efficient solutions, Koen brings deep expertise in numerical methods, system optimization, and software architecture.Show NotesDate Recorded: 2025-10-10Date Released: 2025-11-21Thrust DocsCUB LibraryC++26 Reflection ProposalADSP Episode 39: How Steve Jobs Saved Sean ParentParrotParrot on GitHubSean's C++ Under the Sea KeynoteParrot sumIntro Song InfoMiss You by Sarah Jansen https://soundcloud.com/sarahjansenmusicCreative Commons — Attribution 3.0 Unported — CC BY 3.0Free Download / Stream: http://bit.ly/l-miss-youMusic promoted by Audio Library https://youtu.be/iYYxnasvfx8

Studied Software Engineering at the University of Amsterdam. Founded the Dutch C++ Meetup in 2013 and co-organizes C++ Under the Sea since 2023. He has been programming for more than 25 years, his journey began on his father's Panasonic CF-2700 MSX--and has been hooked ever since. He is also 'the listener' of ADSP the podcast.Paul Grosse-Bley was first introduced to parallel programming with C+MPI at a student exchange to Umeå (Sweden) in 2017 while studying Physics. In the following years he learned more about MPI, OpenMP, OpenACC, Thrust/parSTL and CUDA C++. After finishing his Master's degree in Physics at Heidelberg University (Germany) in 2021, he became a PhD candidate in Computational Science and Engineering researching the acceleration of iterative solvers in sparse linear algebra while being head-tutor for a course on GPU Algorithm Design. He learned using Thrust in 2019 shortly before learning C++ and became enamored with parallel algorithms which led to numerous answers on StackOverflow, contributions on GitHub, his NVIDIA internship in the summer of 2025 and full position starting in February of 2026.Show NotesDate Recorded: 2025-10-10Date Released: 2025-11-14NVIDIA BCM (Base Command Manager)C++11 std::ignoreC++20 std::bind_frontParrotParrot on GitHubParrot Youtube Video: 1 Problem, 7 Libraries (on the GPU)thrust::inclusive_scanSingle-pass Parallel Prefix Scan with Decoupled Look-back by Duane Merrill & Michael GarlandPrefix Sums and Their Applications by Guy BlellochParallel Prefix Sum (Scan) with CUDANVIDIA ON-Demand VideosA Faster Radix Sort ImplementationIntro Song InfoMiss You by Sarah Jansen https://soundcloud.com/sarahjansenmusicCreative Commons — Attribution 3.0 Unported — CC BY 3.0Free Download / Stream: http://bit.ly/l-miss-youMusic promoted by Audio Library
