Abstract

The development of high performance simulation software is an expensive process and often requires specialized support and information about the computational resources and available software tools. The difficulty is increased by the complexity of the phenomena that can be addressed by numerical simulation, along with the increase and evolution of computing resources.
The DOE Advanced Computational Software (ACTS) Collection is a set of software tools developed primarily at DOE labs and that make it easier for programmers to write high performance scientific applications on high end computers. While DOE has been motivated to develop the tools for its own programs, it also encourages their adoption and use by non-DOE computational efforts. The talk will cover issues related to ACTS tool categories and functionalities, scientific applications that have benefited from these tools, mechanisms for supporting, retiring and including tools in the collection, as well as lessons learned by interacting with users and tool developers.

Dr. Osni Marques is a member of the Scientific Computing Group of the High Performance Computing Research Department, at the Lawrence Berkeley National Laboratory (LBNL). Currently, he is the PI for the project Advanced CompuTational Software (ACTS) Collection, funded by the US Department of Energy (DOE). His research interests include the study, implementation and testing of algorithms for the solution of problems in numerical linear algebra, in particular eigenvalue problems, and high-end scientific computing. The eigensolvers he has implemented have been used in applications related to protein motions, acoustics problems in automobile design and structural analyses. Dr. Marques also holds a research position at the UC Berkeley Computer Sciences Dept., and was previously at CERFACS, Toulouse, France, working in numerical linear algebra problems and scientific applications.
