Verified Exascale Computing for Multiscale Applications

The purpose of the VECMA project is to enable a diverse set of multiscale, multiphysics applications — from fusion and advanced materials through climate and migration, to drug discovery and the sharp end of clinical decision making in personalised medicine — to run on current multi-petascale computers and emerging exascale environments with high fidelity such that their output is “actionable”. That is, the calculations and simulations are certifiable as validated (V), verified (V) and equipped with uncertainty quantification (UQ) by tight error bars such that they may be relied upon for making important decisions in all the domains of concern. The central deliverable will be an open source toolkit for multiscale VVUQ based on generic multiscale VV and UQ primitives, to be released in stages over the lifetime of this project, fully tested and evaluated in emerging exascale environments, actively promoted over the lifetime of this project, and made widely available in European HPC centres.

A theme issue dedicated to ‘Multiscale modelling, simulation and computing: from the desktop to the exascale’ has been published in the Transactions of the Royal Society A. You can access the article here: https://t.co/M9r15JPAzP

In preparation for first major release of the VECMA toolkit (June 2019), all developers met for a concentrated development session to ensure that all fast-track codes are stable and contain the features needed to support our internal applications. @fet_eu @exdci_eu @FocusCoE
