How can SMEs benefit from using High Performance Computing (HPC) Cloud

How can SMEs benefit from using High Performance Computing (HPC) Cloud? How can SMEs benefit from using High Performance Computing (HPC) Cloud? Growth in Europe is unthinkable without the 23 million small and medium-sized enterprises (SMEs). They represent 99.8 percent of all European companies and form the foundation for innovation, competition and jobs. SMEs provide two thirds of private sector jobs (almost 90 million) and contribute to more than half of the total added value created by businesses in the EU. Nine out of ten SMEs are actually micro enterprises with fewer than 10 employees. They account for nearly 30%

Road and Scouts: a versioning strategy for large Research software.

Versioning of large research software applications for industry can be sloppy because audiences have different needs. End-users require a clear official version, while research asks for many exploratory versions.

Born in the 1990s, AVBP is combustion software used and developed today by dozens of industrial users and researchers simultaneously. This post will consider whether it is suitable for a semantic versioning strategy.
