Pressio is an open-source computational framework aimed at advancing the field of reduced-order models (ROMs) for dynamical systems in science and engineering. We employ generic programming, and target shared and distributed-memory applications using arbitrary data-types and diverse programming models.

We believe that the key to develop such a capability from the ground up is to properly identify the building blocks and modularize them accordingly. This is the approach we have adopted: the library is broken into several components such that they can be used independently and in a self-contained fashion. One of the main outcome of this is that regardless of your interest in ROMs, you might find useful some of the components of the library.
