16th GPU Day - Massive parallel computing for science and industrial application
The 16th GPU Day will organized by the Wigner Scientific Computation Laboratory, HUN-REN Wigner RCP from May 28-29, 2026 at the HUN-REN Centre (1054 Budapest, Alkotmány utca 29).

The GPU Day is an annually organized international conference series dedicated to massively parallel technologies in scientific and industrial applications for a decade. Its goal is to bring together from academia, developers from industry, and interested students to exchange experiences and learn about future massively parallel technologies. The event provides a unique opportunity to exchange knowledge and expertise on GPU (Graphical Processing Unit), FPGA (Field-Programmable Gate Array), and quantum simulations. As in previous years, we are expecting 80+ participants in person.
For the earlier events see: 2025, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014
Participation is free for students, members of academic institutions, research centers, and universities.
The registration fee is 300 EUR or 120 000 HUF for non-academic participants - please contact the organizers for further information.
The conference will be held in offline form and there are limited places to participate personally on-site. We encourage our former, current and future partners to contribute on the conference. Contributions to the conference are welcome.
