The Consortium for the Advancement of Scientific Software (CASS) is a federation of member organizations committed to the stewardship and advancement of the current and future ecosystem of scientific computing software. Our members support specific scientific communities or provide crosscutting capabilities related to scientific software stewardship. Member organizations coordinate and cooperate through the Consortium to maximize benefit to the ecosystem as a whole.
Targeted scientific software ecosystem
Based on its current membership, CASS focuses primarily on software which has been supported by the U.S. Department of Energy (DOE) Office of Advanced Scientific Computing Research (ASCR), with an emphasis on supporting large-scale high-performance parallel computers and computations, including the Software Technologies developed in the Exascale Computing Project (ECP).
Details of the software in the “CASS ecosystem” can be found in the Software section of the site.
CASS organizational structure
Member organizations may be categorized as core members, who take an active role in consortium governance, or affiliate members, who are in solidarity with the mission of the consortium but do not take an active role in consortium governance. The Consortium is open to new members. DOE sponsorship is not required. Email us for more information.
CASS is governed by a Steering Committee appointed by the members. Core members each have one representative on the Steering Committee, while the affiliate members have one representative for every five affiliates. The Steering Committee is assisted by three officers: a Chair, Vice-Chair, and a Secretary. The Steering Committee is committed to openness and transparency in its governance processes.
CASS member organizations have their own leadership, governance, and activities, which are distinct from those of the Consortium.
Most of the work of CASS is carried out within Working Groups, which are created as needed.

Sponsors and funding
CASS operates on in-kind contributions of effort and other resources from member organizations. As such, it has no budget of its own, and no direct sponsors.
Member organizations, of course, have their own funding sources. The current members of CASS gratefully acknowledge support from the U.S. Department of Energy (DOE) Office of Advanced Scientific Computing Research (ASCR) through the Next-Generation Scientific Software Technologies (NGSST) and Scientific Discovery through Advanced Computing (SciDAC) programs.
