The Advanced CompuTational Software (ACTS) Collection comprises a set of non commercial tools mainly developed at the Department of Energy’s (DOE) laboratories, sometimes in collaboration with universities. These software tools aim to simplify the solution of common and important computational problems, and have substantially benefited a wide range of applications and fields in computational sciences. These benefits are accounted not only for applications running efficiently on high performing computing environments but also realizing computation that would not have been possible otherwise. Nowadays, with the introduction of hardware technologies such as of multi-core, the use of software libraries is key in the development of high end software applications. This is because libraries provide a level of software abstractions in which the robustness, scalability and portability can be easily and reliably passed into the application codes across a large class of computer platforms.
The ACTS project ensures sustained performance of the tools and long term availability on wide range of computer platforms.
