Trilinos Background

The Trilinos Project is an effort to develop algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems. A unique design feature of Trilinos is its focus on packages. Full details of Trilinos and links to package websites can be found at the Trilinos home page.

Meeting Overview

We are pleased to announce the 2023 Trilinos User Group Meeting (TUG23) will be held October 31st through November 2nd, 2023 at Sandia National Laboratories, in Albuquerque, New Mexico.
The tentative agenda is

  • Tuesday AM, Oct. 31st – Keynote Speaker and Product Area/Package Updates
  • Wednesday AM, Nov. 1st – Application and User Talks
  • Thursday AM/PM, Nov. 2nd – Developer’s Day

As in previous years, this will be a hybrid meeting with both virtual and in-person attendees. We do encourage everyone to consider attending in-person, so that we can get together and talk about Trilinos. We are planning to have morning sessions (8am -12pm MDT) so that our European colleagues can join us remotely. The Developers Day will likely run into the afternoon due to the amount of material we would like to cover.

Tutorials and Hack-a-thons

Additionally, we are considering having tutorials and/or hackathons on one or several of the afternoons of Oct. 30th (Monday PM), Oct. 31st (Tuesday PM) and Nov. 1st (Wednesday PM). These will be scheduled based on interest shared on the TUG23 registration, and we will share any additions to the agenda for tutorials and/or hackathon as soon as we can. If you are interested in this, please let us know early with your registration. There are several tutorials available, e.g., Getting Started, Teuchos, Tpetra, Belos, MueLu, Kokkos, NOX, Zoltan, …, so please let us know your interest on the registration. Also based on interest, we are considering having a hackathon during one or more of these afternoons based on interest. If you would like to work with Trilinos developers on your application, please let us know. We would like to connect you to Trilinos developers to help incorporate and use Trilinos in your application.


Although this meeting will be hybrid (i.e., attend in-person at Sandia or online via MS Teams), we are encouraging everyone to come and join us in Albuquerque, New Mexico.
