DAS-4 supports the OpenNebula package for Cloud computing.
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:
- VU University, Amsterdam (VU)
- Leiden University (LU)
- University of Amsterdam (UvA)
- Delft University of Technology (TUD)
- The MultimediaN Consortium (UvA-MN)
- Netherlands Institute for Radio Astronomy (ASTRON)
