FFMK: A Fast and Fault-Tolerant Microkernel-Based System for Exascale Computing
The FFMK project designs, builds and evaluates a system-software architecture to address the challenges expected in Exascale systems. In particular, these challenges include performance losses caused by the mu...

Fast In-Memory Checkpointing with POSIX API for Legacy Exascale-Applications
Exascale systems will be much more vulnerable to failures than today’s high-performance computers. We present a scheme that writes erasure-encoded checkpoints to other nodes’ memory. The rationale is twofold: ...

FFMK: A Fast and Fault-Tolerant Microkernel-Based System for Exascale Computing
In this paper we describe the hardware and application-inherent challenges that future exascale systems pose to high-performance computing (HPC) and propose a system architecture that addresses them. This arch...

Building Large Compressed PDBs for the Sliding Tile Puzzle
The performance of heuristic search algorithms depends crucially on the effectiveness of the heuristic. A pattern database (PDB) is a powerful heuristic in the form of a pre-computed lookup table. Larger PDBs ...

Technische Informatik
In der Informatik verbindet sich das axiomatische, logisch-strukturtheoretische Denken der Mathematik mit dem konstruktiven und ökonomischen, d. h. praktisch-ingenieurmäßigen Handeln der Technik. Die Informati...

Handling Big Data in Astronomy and Astrophysics: Rich Structured Queries on Replicated Cloud Data with XtreemFS
With recent observational instruments and survey campaigns in astrophysics, efficient analysis of big structured data becomes more and more relevant. While providing good query expressiveness and data analysis...

Out-of-Core Parallel Frontier Search with MapReduce
Applying the MapReduce programming paradigm to frontier search yields simple yet efficient parallel implementations of heuristic search algorithms. We present parallel implementations of Breadth-First Frontier...

Transactions and Concurrency Control for Peer-to-Peer Wikis: an Evaluation
Supporting atomic transactions and concurrency control in peer-to-peer networks is difficult because nodes may leave, crash or join at any time. We propose a transaction processing scheme for peer-to-peer netw...

On Consistency Of Data In Structured Overlay Networks
Data consistency can be violated in Distributed Hash Tables (DHTs) due to inconsistent lookups. In this paper, we identify the events leading to inconsistent lookups and inconsistent responsibilities for a key...

Self Management for Large-Scale Distributed Systems: An Overview of the SELFMAN Project
As Internet applications become larger and more complex, the task of managing them becomes overwhelming. “Abnormal” events such as software updates, failures, attacks, and hotspots become frequent. The SELFMAN...

A Structured Overlay for Multi-dimensional Range Queries
We introduce SONAR, a structured overlay to store and retrieve objects addressed by multi-dimensional names (keys). The overlay has the shape of a multi-dimensional torus, where each node is responsible for a con...

Transactions for Distributed Wikis on Structured Overlays
We present a transaction processing scheme for structured overlay networks and use it to develop a distributed Wiki application based on a relational data model. The Wiki supports rich metadata and additional ...
