AM++ is a user-level library for active messages based on the Active Pebbles programming model. AM++ allows message handlers to be run in an explicit loop that can be optimized and vectorized by the compiler and that can also be executed in parallel on multicore architectures. Runtime optimizations, such as message combining and filtering, are also provided by the library, removing the need to implement that functionality at the application level.

The distribution of open source software is one way that CREST contributes to the wealth of scientific research at Indiana University and throughout the country. The production of open source software significantly enhances the value of scholarly work due to reproducibility andability of scientific research. The open source software created by CREST and its affiliates boosts IU’s competitive footing for federal grant funding, which in turn, brings federal research monies and new high-quality jobs into the state. Also used in the private sector, these open source software products aid in the development of the Indiana economy.
