Final report on deployment of consolidated platform and the overall architecture

This document is the final report about the activities of the Work Package 4 (WP4), aiming at provisioning a consistent e-infrastructure gradually integrating the existing isolated software solutions in the structural biology field into a single computing and data processing environment, based on the state of the art grid and cloud open source software tools and frameworks. This report follows the documents D4.3, MS14, D4.5 and MS15, respectively delivered at project month 15, 24, 26, 34, so that mostly the progress achieved until project month 36 not already described in the previous D4.5 ten months ago will be reported here, with references to MS15 when possible. The document starts with an updated description of the resources potentially available for the project from the EGI e-infrastructure, on top of which we built the consolidated West-Life platform. It then presents a detailed view of resource usage and their geographical distribution in the third and last year of the project, as obtained from the EGI Accounting Portal. The remaining of the document reports in details the final achievements about the three main aspects of the platform: the consolidated job management mechanism, the programmatic access to datasets and the unified security and accounting model

West-Life: A Virtual Research Environment for structural biology

The West-Life project (https://about.west-life.eu/)is a Horizon 2020 project funded by the European Commission to provide data processing and data management services for the international community of structural biologists, and in particular to support integrative experimental approaches within the field of structural biology. It has developed enhancements to existing web services for structure solution and analysis, created new pipelines to link these services into more complex higher-level workflows, and added new data management facilities. Through this work it has striven to make the benefits of European e-Infrastructures more accessible to life-science researchers in general and structural biologists in particular

Overview of the COMPASS results

COMPASS addressed several physical processes that may explain the behaviour of important phenomena. This paper presents results related to the main fields of COMPASS research obtained in the recent two years, including studies of turbulence, L–H transition, plasma material interaction, runaway electron, and disruption physics: • Tomographic reconstruction of the edge/SOL turbulence observed by a fast visible camera allowed to visualize turbulent structures without perturbing the plasma. • Dependence of the power threshold on the X-point height was studied and related role of radial electric field in the edge/SOL plasma was identified. • The effect of high-field-side error fields on the L–H transition was investigated in order to assess the influence of the central solenoid misalignment and the possibility to compensate these error fields by low-field-side coils. • Results of fast measurements of electron temperature during ELMs show the ELM peak values at the divertor are around 80% of the initial temperature at the pedestal. • Liquid metals were used for the first time as plasma facing material in ELMy H-mode in the tokamak divertor. Good power handling capability was observed for heat fluxes up to 12 MW m−2 and no direct droplet ejection was observed. • Partial detachment regime was achieved by impurity seeding in the divertor. The evolution of the heat flux footprint at the outer target was studied. • Runaway electrons were studied using new unique systems—impact calorimetry, carbon pellet injection technique, wide variety of magnetic perturbations. Radial feedback control was imposed on the beam. • Forces during plasma disruptions were monitored by a number of new diagnostics for vacuum vessel (VV) motion in order to contribute to the scaling laws of sideways disruption forces for ITER. • Current flows towards the divertor tiles, incl. possible short-circuiting through PFCs, were investigated during the VDE experiments. The results support ATEC model and improve understanding of disruption loads
