A proposed framework for designing and implementing a Service Portfolio for the European Science Data Center and SKA

Service Portfolio Management (SPM) is a key component of any proposed design and implementation of a Service Portfolio. The goal of SPM is to both define and maintain a service portfolio, while considering the demands and requirements of customers and defining the specifications of new or improved services. Scenarios and examples are given, which demonstrate that well structured SPM procedures results in a cleaner, clearer communication of services, whether through a central SKA portal, the SKA Marketplace, or through targeted promotion material as well as other external catalogues which could be leveraged, e.g. the eInfraCentral project and the European Open Science Cloud Marketplace. Two service portfolio scenarios are described listing relevant services.

AAI Requirements and AAI Architecture Design for the ESDC

 

This report presents the SKA requirements regarding AAI using the results of a survey and other analyses carried out as part of the AENEAS project. Current AAI technologies are covered and a proposed AAI architecture is presented with the respective functional
components that are needed to meet the requirements. Finally the deliverable proposes recommendations how this architecture should evolve.

Recommendations on the design of user interfaces for data processing, re-processing, analysis and visualization for the ESDC

In this document we analyse in detail the results of the AENEAS WP5 Surveys for User communities, in order to identify the major gaps with respect to the user interaction model suggested for the ESRC and provide recommendations on the design of interfaces for data processing, re-processing, analysis, and visualization for the ESRC.

Recommendations on the design of user interfaces for data discovery, access, and retrieval for the ESDC

 

In this document, by taking into account the users’ experience about archival interfaces (reported in the D5.1-WP5 Survey results analysis) and the D5.2-WP5 gap analysis, we analyse in detail the archival interfaces exposed by some of the major radio facilities in order to provide recommendations on the design of interfaces for data discovery, access, and retrieval for the ESDC.

Initial System Sizing for the ESDC

This document provides the basis for the first AENEAS Cost Estimate for the capital outlay associated with a European SKA Regional Centre (ESRC). This document is a companion of the AENEAS ESRC Cost Model spread sheet. This costing follows the model adopted for the SKA SDP in order to allow consistency across the project. The estimated CAPEX cost of the European SKA regional centre at this
time is approximately Euro 30M initial outlay (2025 prices) followed by an annual cost of Euro 10M for storage growth. It is suggested that a refresh cycle of 5 years is appropriate.

In this AENEAS document we present the key elements needed for the software infrastructure required for the ESDC, these include: (i) middleware elements to support distributed compute models such as cloud compute, HTC (High Throughput Computing), HPC (High Performance Computing) and container-based cloud compute; (ii) the top-level software stack providing an environment for efficient distributed analysis of data; and, (iii) elements required for a federated ESDC, including services.

Inventory of Facilities and Providers for the European regional center for the Square Kilometre Array (SKA)

The European SKA Data Centre (ESDC) is expected to consist of (high performance) computing facilities and data (storage) centers connected by a high speed network. This report presents a preliminary overview of facilities and providers that may form (part of) the ESDC. The list is a starting point for further investigations of technical suitability, governance and funding  for the ESDC.

Compute, network and storage infrastructure of the European regional center to support SKA key science

This document presents an initial system sizing for a European SKA Data Centre (ESDC), which would serve as an SKA Regional Centre (SRC) for Europe. The document presents initial sizing estimates for the storage, compute and data ingest capabilities required by such
a centre in order to support the European research community in achieving the High Priority Science Objectives (HPSOs) of the SKA project.

Recommendations for SKA regional centers based on surveys data from the astronomy user community and facilities

This document uses results of the AENEAS Survey for Astronomical Facilities and their User communities, in order to identify the major gaps with respect to the expected SKA user support system. The conclusions of this document should be considered when designing the  European SKA Regional Centre (ESRC) as well as other SRC around the world.

Posted on: Aug 21, 2018 | Authors: Marcella Massardi

Main Findings

The regional centers of the SKA need should provide the resources and incentives to change existing science extraction workflows and change the currently prevailing "single desktop" mentality within the astronomical community. These include (1) establishing a trust inregional centers to provide robust and high quality data reduction tools; (2) engaging user expertise in the development of tools/services for the regional centers; (3) providing well-coordinated communication to support the user community and more.

Recommendations for data transfer and storage for the European Science Data Center for the Square Kilometre Array

This document provides a set of best practice recommendations to optimise network and storage performances for the ESCD. The document is based on the analysis of intercontinental network investigations involving GEANT, AARNET and SANREN and the performance measurements of two big data transfer applications, GridFTP and FDT in the lab and long-distance environments. The recommendations will be used to select the data transfer protocols and applications for the ESDC suitable to support the high performance long distance data transfers required by the SKA computing models.

Main Findings

Although inter-continental network paths are still being investigated at 100 Gigabit, we have demonstrated that the academic networks can be engineered to provide congestion free paths and have the capability and stability to move SKA data at the required rates.
