A Scalable General Purpose System for Large-Scale Graph Processing

Graph analytics is an important and computationally demanding class of data analytics. It is essential to balance scalability, ease-of-use and high performance in large scale graph analytics. As such, it is necessary to hide the complexity of parallelism, data distribution and memory locality behind an abstract interface. The aim of this work is to build a scalable graph analytics framework that does not demand significant parallel programming experience based on NUMA-awareness.
The realization of such a system faces two key problems:
(i)~how to develop a scale-free parallel programming framework that scales efficiently across NUMA domains; (ii)~how to efficiently apply graph partitioning in order to create separate and largely independent work items that can be distributed among threads.

Caught in the conundrum: neoliberalism and education in post-conflict Northern Ireland: Exploring Shared Education

Northern Ireland (NI) is emerging from a violent period in its troubled history and remains a
society characterized by segregation between its two main communities. Nowhere is this more
apparent than in education, where for the most part Catholic and Protestant pupils are
educated separately. During the last 30 years there has been a twofold pressure placed on the
education system in NI - at one level to respond to intergroup tensions by promoting
reconciliation, and at another, to deal with national policy demands derived from a global neoliberalist
economic agenda. With reference to current efforts to promote shared education
between separate schools, we explore the uneasy dynamic between a school-based
reconciliation programme in a transitioning society and system-wide values that are driven by
neo-liberalism and its organizational manifestation - new managerialism. We argue that whilst
the former seeks to promote social democratic ideals in education that can have a potentially
transformative effect at societal level, neoliberal priorities have the potential to both subvert
shared education and also to embed it.

The Adequacy of Traveller Education in Northern Ireland

The issues facing Travellers, including those associated with education are often linked to social exclusion, widespread disadvantage and discrimination (Reynolds, McCartan, and Knipe 2003




). The Office for Standards in Education (Office for Standards in Education 1999




) referred to Gypsy Traveller pupils as ‘the most at risk in the education system.’ Within this article issues pertaining to Traveller education are discussed and in particular accessing education provision in Northern Ireland. The article focuses on the views of the statutory and voluntary sector to assess the adequacy and effectiveness of educational provision for Traveller children and young people and reviews the policies in place relating to the provision of education for Travellers in Northern Ireland. It also considers the issue of segregated education for the Traveller community and how for some this segregation can exacerbate social exclusion, disadvantage and discrimination.

Challenges and barriers in primary school education: The experiences of Traveller children and young people in Northern Ireland

Exclusion, discrimination and widespread disadvantage are issues common to the Traveller community. Children from the Traveller community are often seen as the most at risk within the education system in respect of attendance, attainment and bullying. In this article, we consider the views of Traveller children and parents with respect to primary level education in Northern Ireland and assess the level of support that exists to help Traveller children within the education system. The findings from the research are discussed with reference to institutional discrimination and the varying experiences of children and their families, including an identification of positive attitudes to education contrary to typical stereotypes.

Shared Education in contested spaces: How collaborative networks improve communities and schools

Societies which suffer from ethnic and political divisions are often characterised by patterns of social and institutional separation, and sometimes these divisions remain even after political conflict has ended. This has occurred in Northern Ireland where there is, and remains, a long-standing pattern of parallel institutions and services for the different communities. A socially significant example lies in the education system where a parallel system of Catholic and Protestant schools has been in place since the establishment of a national school system in the 1830s. During the years of political violence in Northern Ireland a variety of educational interventions were implemented to promote reconciliation, but most of them failed to create any systemic change. This paper describes a post-conflict educational initiative known as Shared Education which aims to promote social cohesion and school improvement by encouraging sustained and regular shared learning between students and broader collaboration between teachers and school leaders from different schools. The paper examines the background to work on Shared Education, describes a ‘sharing continuum’ which emerged as an evaluation and policy tool from this work and considers evidence from a case study of a Shared Education school partnership in a divided city in Northern Ireland. The paper will conclude by highlighting some of the significant social and policy impact of the Shared Education work.

From brown envelopes to community benefits: the co-option of planning gain agreements under deepening neoliberalism

The provision of physical and social infrastructure in the form of roads, green spaces and community facilities has traditionally been provided for by the state through the general taxation system. However, as the state has been transformed along more neoliberal lines, the private sector is increasingly relied upon to deliver public goods and services. Planning gain agreements have flourished within this context by offering another vehicle through which local facilities are privately funded. Whilst these agreements reflect the broader dynamics of neoliberalism, they are commonly viewed as a tool which can be employed to challenge these very dynamics by empowering local communities to secure more just planning outcomes. This paper counters such claims. Based on evidence gathered from 80 interviews with planners, councillors, developers and community groups in Ireland, the paper demonstrates how planning gain agreements have been strategically redeployed by the holders of political and economic power to serve their own ends. In seeking to understand why and how this has occurred, specific consideration is given to the changing power dynamics between the state and private capital under neoliberalism. The paper highlights how institutional arrangements have enabled developers to infiltrate the political sphere in more subtle and implicit ways than ever before. We conclude by arguing that planning gain must be understood as a mechanism which has been manipulated in ways which essentially work to preserve and enhance, rather than redress, existing power imbalances in the planning system by facilitating large scale transfers of wealth upwards in society.

On the Virtualization of CUDA Based GPU Remoting on ARM and X86 Machines in the GVirtuS Framework

The astonishing development of diverse and different hardware platforms is twofold: on one side, the challenge for the exascale performance for big data processing and management; on the other side, the mobile and embedded devices for data collection and human machine interaction. This drove to a highly hierarchical evolution of programming models. GVirtuS is the general virtualization system developed in 2009 and firstly introduced in 2010 enabling a completely transparent layer among GPUs and VMs. This paper shows the latest achievements and developments of GVirtuS, now supporting CUDA 6.5, memory management and scheduling. Thanks to the new and improved remoting capabilities, GVirtus now enables GPU sharing among physical and virtual machines based on x86 and ARM CPUs on local workstations,computing clusters and distributed cloud appliances.
