Sustainable computational science : the

Computer science o‚ers a large set of tools for prototyping, writing, running, testing, validating, sharing and reproducing results, however computational science lags behind. In the best case, authors may provide their source code as a compressed archive and they may feel con€dent their research is reproducible. But this is not exactly true. Jonathan Buckheit and David Donoho proposed more than two decades ago that an article about computational results is advertising, not scholarship. ‘e actual scholarship is the full so‰ware environment, code, and data that produced the result. ‘is implies new workƒows, in particular in peer-reviews. Existing journals have been slow to adapt: source codes are rarely requested, hardly ever actually executed to check that they produce the results advertised in the article. ReScience is a peer-reviewed journal that targets computational research and encourages the explicit replication of already published research, promoting new and open-source implementations in order to ensure that the original research can be replicated from its description. To achieve this goal, the whole publishing chain is radically di‚erent from other traditional scienti€c journals. ReScience resides on GitHub where each new implementation of a computational study is made available together with comments, explanations, and so‰ware tests.
