VECMA VVUQ Toolkit Month 9 Beta Release

VECMA VVUQ Toolkit Month 9 Beta Release

The VECMA project has previously made three releases internal to the project (at Months 1, 3 and 6), and have already successfully applied two components (FabSim3 and EasyVVUQ) to multiple applications. 

The Month 9 release of the VECMA VVUQ Toolkit has occurred on schedule, on Thursday 14 March, 2019. It is comprised of two parts: (i) a new version of the EasyVVUQ software and (ii) a new release of FabSim3 containing various additional features.

In addition to the latest versions of FabSim3 and EasyVVUQ, the Month 9 release includes an integration with the project’s QCG middleware, combined with the incorporation of additional application domains, as well as Docker and Singularity images for FabSim3. Both FabSim3 and EasyVVUQ are now in open development, that is they can be checked, modified and used by anyone at any time.  Technical details of the release are provided below.
