The VECMA toolkit (VECMAtk) can be found on its own designated webpage

The VECMAtk establishes a platform for verification, validation and uncertainty quantification (VVUQ). The goal is to provide tools that can be combined to capture complex scenarios, applied to applications in disparate domains, and used to run multiscale simulations on any desktop, cluster or supercomputing platform.

The VECMAtk is periodically updated, with minor releases every 3 months, and major releases every 12 months.

Month 21 release

The Month 21 release (13 March 2020) is made up of the following tools:

  • FabSim3
  • EasyVVUQ
  • QCG Pilot Job
  • QCG-Now
  • QCG-Client
  • EasyVVUQ-QCGPilotJob

Some new features and updates have been made in M21 release.

For EasyVVUQ, it has:

  • Point Collocation method for PCE sampling.
  • GaussianProcessSurrogate class which will serve as a basis and testing ground for surrogate based workflows
  • Added quasirandom sampling classes: LHCSampler and HaltonSampler.
  • JSONDecoder class. It allows codes to use JSON as output format.

And the tool has the following updates:

  • Started measuring test coverage using coveralls
  • Numerous bug fixes

For FabSim3, the tool has the following new feature:

  • Added automated configuration of machines_user.yml file (#173 , #162)

FabSim3 has been updated with:

  • Fixed Multi threading bug, allowing for much larger ensemble sizes (#175#174)
  • Disabled execution of run_prefix commands on the remote machine during the job submission (#171#176)
  • Defined additional functional tests for FabSim3 and plugins (#125)

MUSCLE3 has been released with the new tag: 0.3.0. MUSCLE3 has now with support for Fortran model components and various small fixes and improvements. The e-MUSC project has contributed MUSCLE 3 to the VECMA toolkit.

The QCG-PJ tool have been released with the new tags and have included several bugfixes, in particular:

  • bugfix related to the ‘job temporarily disabled’ error
  • bugfix related to the node launcher agent wait time

The QCG-EasyVVUQ-QCGPJ tool has some new features as follows:

  • possibility to use `EXEC_ONLY` option for `SubmitOrder` that limits the application of the pilot job tasks just to the actual execution of model (with this option decoding is executed without PJ)
  • possibility to define a logging level of the QCG Pilot Job software directly from the API
  • an internal tutorial material that can be helpful for new EasyVVUQ-QCGPJ users.
