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.

Antonio y Gabriel de Sancha, libreros de la Ilustración, y sus relaciones comerciales con Inglaterra

In this article we take as our point of departure the booksellers' catalogues printed by the Sanchas during the reigns of Charles III and Charles IV, as well as the catalogues issued by their London correspondents the booksellers Thomas Payne and Benjamin White. We contextualize the business relationship which developed between the Sanchas and the London booksellers as a direct result of Gabriel de Sancha's visit to London in the Summer of 1784. This study highlights the significance of a parallel offer of recently published books in English and Spanish in some of the most renowned bookshops in Madrid and London between the mid 1780s and the years immediately before the Peninsular War, a circumstance that no doubt stimulated curiosity on both sides and sped up the transfert culturel between both countries. Notwithstanding their business and private troubles, Antonio and Gabriel de Sancha, self-reliant entrepreneurs and cultural intermediaries, were able to establish a dynamic book trade flow which did not imply the subordination of Spain to England.
