Fortran 2023 for you: Features and tools

NHR PerfLab seminar talk on March 10, 2025 Speaker: Katherine Rasmussen (Lawrence Berkeley National Laboratory) Title: Fortran 2023 for you: Features and tools Slides: https://hpc.fau.de/files/2025/03/PerfLab-Talk-Fortran-2023-for-you_-Features-and-tools.pdf Video on slide 25: https://youtu.be/bR_h9MAcbNU Abstract: Fortran has been used in scientific programming for decades, and it continues to be vital in helping scientists perform critical research. In this talk, I will explore how to make Fortran work better for you. The latest standard of the language was published in 2023 and many new helpful features from that and other recent standards have been introduced. This talk will discuss features in the language that help address modern programming needs and how they might help you. This includes do-concurrent and a smattering of helpful intrinsic functions. The talk will also introduce tools and communities that support and contribute to a vibrant Fortran developer community. This will include a discussion of Julienne, a unit testing framework for modern Fortran that helps support the agile software practice of test-driven development.
