An OpenSHMEM Implementation for the Adapteva Epiphany Coprocessor

This paper reports the implementation and performance evaluation of the OpenSHMEM 1.3 specification for the Adapteva Epiphany architecture within the Parallella single-board computer. The Epiphany architecture exhibits massive many-core scalability with a physically compact 2D array of RISC CPU cores and a fast network-on-chip (NoC). While fully capable of MPMD execution, the physical topology and memory-mapped capabilities of the core and network translate well to Partitioned Global Address Space (PGAS) programming models and SPMD execution with SHMEM.Comment: 14 pages, 9 figures, OpenSHMEM 2016: Third workshop on OpenSHMEM and Related Technologie

'Penny banks' in Glasgow, 1850-1914

This paper explores the extent and nature of ‘Penny bank’ saving in Glasgow during the second half of the nineteenth century. Penny banks existed as part of the network of philanthropic organisations in the quintessential industrial city, and they were frequented by the poorer sections of the working class – those for whom saving represented a difficult and occasionally sacrificial effort. They were a voluntary and individualist decision to engage in saving, in contrast to the mutual organisations, such as friendly and industrial welfare societies which also proliferated in this period. The enormous success of penny banks in Glasgow, and throughout the United Kingdom, is powerful evidence that a great deal of saving was happening, even amongst the poorest sections of society. Careful examination of the activities of two penny banks suggests that they operated both as short-term liquidity stores and as vehicles for longer-term and larger-amount savings

Is Understanding Reducible?

Despite playing an important role in epistemology, philosophy of science, and more recently in moral philosophy and aesthetics, the nature of understanding is still much contested. One attractive framework attempts to reduce understanding to other familiar epistemic states. This paper explores and develops a methodology for testing such reductionist theories before offering a counterexample to a recently defended variant on which understanding reduces to what an agent knows

Recent work on the proof paradox

Recent years have seen fresh impetus brought to debates about the proper role of statistical evidence in the law. Recent work largely centres on a set of puzzles known as the ‘proof paradox’. While these puzzles may initially seem academic, they have important ramifications for the law: raising key conceptual questions about legal proof, and practical questions about DNA evidence. This article introduces the proof paradox, why we should care about it, and new work attempting to resolve it

Unravelling strange quarks in nucleon structure

We present a discourse on the stages of discovery that have led to a deeper understanding of the role played by strange quarks in the structure of the nucleon.Comment: 6 pages, 2 figures; prepared for the proceedings of Achievements and New Directions in Subatomic Physics: Workshop in Honour of Tony Thomas' 60th Birthda
