Performance Study of Software AER-Based Convolutions on a Parallel Supercomputer
This paper is based on the simulation of a convolution model for bioinspired
neuromorphic systems using the Address-Event-Representation (AER)
philosophy and implemented in the supercomputer CRS of the University of
Cadiz (UCA). In this work we improve the runtime of the simulation, by
dividing an image into smaller parts before AER convolution and running each
operation in a node of the cluster. This research involves a test cases design in
which the optimal parameters are set to run the AER convolution in parallel
processors. These cases consist on running the convolution taking an image
divided in different number of parts, applying to each part a Sobel filter for
edge detection, and based on the AER-TOOL simulator. Execution times are
compared for all cases and the optimal configuration of the system is discussed.
In general, CRS obtain better performances when the image is divided than for
the whole image.Ministerio de Ciencia e Innovación TEC2009-10639-C04-0
The Road to Quantum Computational Supremacy
We present an idiosyncratic view of the race for quantum computational
supremacy. Google's approach and IBM challenge are examined. An unexpected
side-effect of the race is the significant progress in designing fast classical
algorithms. Quantum supremacy, if achieved, won't make classical computing
obsolete.Comment: 15 pages, 1 figur
NSSDC Conference on Mass Storage Systems and Technologies for Space and Earth Science Applications, volume 1
Papers and viewgraphs from the conference are presented. This conference served as a broad forum for the discussion of a number of important issues in the field of mass storage systems. Topics include magnetic disk and tape technologies, optical disks and tape, software storage and file management systems, and experiences with the use of a large, distributed storage system. The technical presentations describe, among other things, integrated mass storage systems that are expected to be available commercially. Also included is a series of presentations from Federal Government organizations and research institutions covering their mass storage requirements for the 1990's
