Abstract: Trilinos I/O Support (Trios) is a new capability area in Trilinos that serves two important roles: (1) it provides and supports I/O libraries used by in-production scientific codes; (2) it provides a research vehicle for the evaluation and distribution of new techniques to improve I/O on advanced platforms. This paper provides a brief overview of the production-grade I/O libraries in Trios as well as some of the ongoing research efforts that contribute to the experimental libraries in Trios.

Keywords: Parallel I/O, I/O libraries, data staging, data services
