Chronos: a NoSQL system on flash memory for industrial process data
Within Électricité de France (EDF) hydroelectric power stations, IGCBoxes are industrial mini PCs dedicated to industrial process data archiving. These equipments expose distinctive features, mainly on their storage system based exclusively on flash ...
On visualizing large multidimensional datasets with a multi-threaded radial approach
In this paper, we study how to visualize large amounts of multidimensional data with a radial visualization. For such a visualization, we study a multi-threaded implementation on the CPU and the GPU. We start by reviewing the approaches that have ...
Benchmarking SQL on MapReduce systems using large astronomy databases
In the era of bigdata, with a massive set of digital information of unprecedented volumes being collected and/or produced in several application domains, it becomes more and more difficult to manage and query large data repositories. In the framework of ...
Scalable graph-based OLAP analytics over process execution data
In today's knowledge-, service-, and cloud-based economy, businesses accumulate massive amounts of data from a variety of sources. In order to understand businesses one may need to perform considerable analytics over large hybrid collections of ...
