HoP User Guide

Franco Buffa, Giampaolo Serra & Sergio Poppi
HoP stands for Holography Package for the Sardinia Radio Telescope. It is a software implementing the well-established phase-coherent microwave holography method for the surface diagnostic of the high gain antennas. This method allows to map the surface deformations of a large reflector antenna by exploiting the relationship between the aperture field and the far-field pattern. Given the complex far-field pattern, one can compute the map of the surface deformations with respect to the antenna ideal...

Installation, configuration, deployment and run guide for the Credential Delegation Service. Administator's guide 1.0.

Sara Bertocco & Giuliano Taffoni
The Credential Delegation is a client and server implementation of the IVOA Credential Delegation Protocol. The Credential Delegation Protocol allows a client program to delegate a user's credentials to a service such that that service may make requests of other services in the name of that user. The service provides a RESTful interface. It requires an SQL Resource DataBase Management Service (RDBMS) as default persistence layer built-in and it provides a RESTful interface. This guide...

Sara Bertocco & Giuliano Taffoni
Access Control is a client and server authentication and authorization implementation for user and group management. It has LDAP as default persistence layer built-in and it provides a RESTful interface to authentication, authorization and user and group management. This technical report provides an administrators guide to install, configure and manage the service known as Group Management Service, based on software APIs open source released by CADC (Canadian Astronomy Data Center). The guide includes instructions on...

Direct N-body code designed for heterogeneous platforms

David Goz, Luca Tornatore, Sara Bertocco & Giuliano Taffoni
The ExaNeSt H2020 project aims at the design and development of an exascale ready supercomputer with a low energy consumption profile but able to support the most demanding scientific and technical applications. The project will produce a prototype based on hybrid hardware (CPUs+accelerators) implementing a co-design approach where scientific applications requirements are driving the hardware design. Astrophysical codes are playing a fundamental role to validate the exascale platform. We present strategies adopted in order to...

Performance of direct N-body code on ARM64 SoC

David Goz, Luca Tornatore, Sara Bertocco & Giuliano Taffoni
The ExaNeSt H2020 project will produce a prototype based on ARM64 CPUs and FPGA-based accelerators implementing a co-design approach where scientific applications requirements are driving the hardware design. We present strategies adopted in order to port our direct N-body code on an ARM SoC cluster, called INCAS, deployed at INAF-OATs. Each computational node is based on 64-bit ARMv8 Cortex-A72/Cortex-A53 core design, powered by the Mali-T864 GPU. We present the strategies to optimize the code and...

Installation, configuration, deployment and run guide for the VOSpace Service. Administator's guide 1.0

Sara Bertocco & Giuliano Taffoni
The VOSpace is a client and server implementation of the IVOA VOSpace interface. The VOSpace is a lightweight interface to distributed storage specifying how VO (Virtual Observatory) agents and applications can use network attached data stores to persist and exchange data in a standard way. It is supposed to sit on top of existing storage solutions and the underlying storage system is not specified. The service requires an SQL Resource DataBase Management Service (RDBMS) as...

CADC logging utility administration guide. Administrator's guide 1.0

Sara Bertocco & Giuliano Taffoni
The core module of the opencadc software (https://github.com/opencadc) contains a logging management utility called cadc-log. This utility allows to manage logging level and logging administration tasks access. This guide explains how to install, configure and manage this logging utility.

L'Alternanza Scuola Lavoro in INAF a.s. 2016/2017

Livia Giacomini & Marco Ziggiotti
In Italia, tutti gli studenti frequentanti un Istituto di Istruzione Superiore devono per legge effettuare nel corso del triennio finale dei progetti di Alternanza Scuola Lavoro (ASL). L’obbligatorietà dell’ASL riguarda nel 2017/2018 circa 1 milione e mezzo di studenti. Questo documento costituisce la prima analisi globale delle attività didattiche di ASL svolte da INAF nell’anno 2016/2017, per un totale di 35.800 ore per studente erogate nelle 15 sedi coinvolte sul territorio italiano..

VOSpace Backend Service Developers Guide 1.0

Sara Bertocco & Giuliano Taffoni
The vospace-backend is a storage service management used to integrate a VOSpace interface implementation with a storage solution. This software module persists the information linking a VOSpace Node Identifier with a vospace backend stored file, so it is able to return URIs to access the content of the data objects. The storage solution can be changed thanks to a plug-in architecture allowing to plug-in at run time different storage solutions simply implementing an abstract java...

Direct N-body code designed for a cluster based on heterogeneous computational nodes

David Goz, Luca Tornatore, Sara Bertocco & Giuliano Taffoni
The ExaNeSt H2020 project is developing an exascale ready prototype based on hybrid hardware (CPUs+accelerators). Astrophysical codes are used to test and validate the exascale platform. At the same time, astrophysical applications must be re-engineered in order to exploit heterogeneous hardware. We present and test the parallel scheme of a state-of-the-art direct N -body code (called ExaHiGPUs) conceived to be run on hybrid architecture.
