Modular Hack Weekend Winners Announced!

[Modular]

What a weekend! Our community’s ambition, creativity, and technical depth blew us away.

After much deliberation, here are the winners of this weekend’s competition:

First Place – Fast Fourier Transform by Martin Vuyk
Prize: RTX 5090
GitHub repo

[hackathon 2025-06] Fast Fourier Transform

Implementation Link. This is my first time programming anything on a GPU beyond just using Tensorflow. As many people have said, it was surprisingly easy. I also decided to do something I’m familiar with and is solved in 1 dimension to avoid the many headaches that arise with multidimensional tensors. I went for the Fast Fourier Transform because I’ve run this algorithm by hand in university and it is in my original field of study. Also because while I was doing it I realized how parallelizab…

Second Place – Mojo-Lapper: GPU-Accelerated Interval Overlap Detection by Seth Stadick
GitHub repo
Prize: RTX 5080

[Hackathon] Mojo-Lapper: GPU-Accelerated Interval Overlap Detection

Mojo-Lapper: GPU-Accelerated Interval Overlap Detection TL;DR: I built an interval overlap detection library in Mojo with both CPU and GPU implementations, achieving 60-140x speedups on GPU vs CPU using the BITS algorithm. The same Lapper data structure is usable in Host code and Device kernel code. What I Built Mojo-Lapper is an implementation of the BITS (Binary Interval Search Tree) algorithm for fast interval overlap detection. Think genomics (finding overlapping genes), time series analysi…

Third Place – QLabs: Quantum Circuit Simulator with GPU Acceleration by Thomas Trenty
Prize: RTX 5070

[Hackathon] QLabs: Quantum Circuit Simulator with GPU Acceleration🔥

Hi, I’m Thomas, I’m excited to share my first project in Mojo and my first experience with GPU programming. As a final-year Master’s student in Computer Science specializing in AI, I’ve always been passionate about CPU parallel computing and was eager to explore GPU programming. I developed QLabs, a Quantum Circuit Simulator with GPU support, for the Modular Hack Weekend. This project builds on my prior CPU-based implementation, inspired by the research paper “How to Write a Simulator for Quant…
