DAS-4 Overview

DAS-4 (The Distributed ASCI Supercomputer 4) is a six-cluster wide-area distributed system designed by the Advanced School for Computing and Imaging (ASCI). DAS-4 is funded by NWO/NCF (the Netherlands Organization for Scientific Research), and the participating universities and organizations (see below). As one of its distinguishing features, DAS-4 employs a number of HPC Accelerators (e.g., currently various GPU types, FPGA's are also planned) and a novel internal wide-area interconnect based on light paths.

The goal of DAS-4 is to provide a common computational infrastructure for researchers within ASCI, who work on various aspects of parallel, distributed, grid and cloud computing, and large-scale multimedia content analysis. The following institutes and organisations are directly involved in the realization and running of DAS-4:

DAS-4 cluster at VU University, Amsterdam
DAS-4 cluster at ASTRON, Dwingeloo
DAS-4 cluster at Leiden University
DAS-4 clusters at UvA/UvA-MN, Amsterdam
DAS-4 cluster at Delft University of Technology
