Scalable Exploratory Search on Knowledge Graphs Using Apache Spark
2018 IEEE 27th International Conference on Enabling Technologies: Infrastructure for Collaborative Enterprises (WETICE).
TL;DR:
An incremental query execution model RAPIDFacet is proposed, that exploits the iterative nature of faceted search and reuses intermediate results and is built on top of Apache Spark which naturally supports iterative models and the Nested Triplegroup Data Model and Algebra.

Contributors: J. Kun*, M. O’Brien n & B. Sullivan n
TL;DR:
Low-treedepth colorings are introduced as an alternative to the commonly used p-centered colorings and a co-NP-completeness reduction is given for recognizing p-linear colorings, and polynomial upper bounds are established via constructive coloring algorithms in trees and intervals graphs and it is conjecture that aPolynomial relationship is in fact the worst case in general graphs.

Resolving the GPU responsiveness dilemma through program transformations
Frontiers of Computer Science, 12(3), 545–559.
author keywords: program transformation; GPU; integrated architecture; responsiveness
TL;DR:
This study identifies the GPU responsiveness dilemma: host busy polling responds quickly, but at the expense of high energy consumption and interference with co-running CPU programs; interrupt-based notification minimizes energy and CPU interference costs, but suffers from substantial response delay.
