Distributed Systems group

Welcome to the home page of the Distributed Systems (DS) group, which is one of the sections of the Department of Software and Computer Technology (SCT) of the Faculty Electrical Engineering, Mathematics, and Computer Science (EEMCS) of Delft University of Technology. The DS group was formerly called the Parallel and Distributed Systems (PDS) group.

The mission of the DS group is to model, design, implement, and analyze distributed systems and algorithms. Our research is fundamental, aimed at the development and evaluation of new generic concepts in systems software, and application-driven, motivated by important application areas, such as e-science, online games, graph processing, and online social networks. Much of it is experimental, validating the proposed new concepts by means of implementation and deployment in prototypes that are used in the real world. The three research areas of the DS group are resource management and scheduling in distributed computing systems, big data processing, and cooperative systems.

The teaching of the DS group consists of BSc courses on computer systems, operating systems, and networks, and of MSc courses on Distributed Algorithms, Distributed Systems, Cloud Computing, Applied Security, and High-Performance Computing.

The DS group has excellent computing facilities for its experimental research. We have a 48-node cluster computer, which is part of the NWO-funded fifth-generation Distributed ASCI Supercomputer (DAS-5). Each node consists of two 2.4-GHz eight-core CPUs, 64 GB of main memory, and 2 4-TB disks, and a total amount of storage in the headnodes of 192 TB. All the nodes are connected by a 10-Gb Infiniband network and a Gigabit Ethernet network. The entire cluster is connected by a wide-area network to similar systems at the other universities participating in ASCI.
