ECP Awards $34m for Software Development

OAK RIDGE – The Department of Energy’s Exascale Computing Project (ECP) today announced the selection of 35 software development proposals representing 25 research and academic organizations.

The awards for the first year of funding total $34 million and cover many components of the software stack for exascale systems, including programming models and runtime libraries, mathematical libraries and frameworks, tools, lower-level system software, data management and I/O, as well as in situ visualization and data analysis.

Exascale refers to computing systems at least 50 times faster than the nation’s most powerful supercomputers in use today.

According to Paul Messina, director of the ECP, “These software development awards are a major first step toward developing a comprehensive and coherent software stack that will enable application developers to productively write highly parallel applications that can portably target diverse exascale architectures.” Messina continued, “After a lengthy review, we are pleased to announce that we have selected 35 proposals for funding. The funding of these software development projects, following our recent announcement for application development awards, signals the momentum and direction of ECP as we bring together the necessary ecosystem and infrastructure to drive the nation’s exascale imperative.”
