SPP2037 - Scalable Data Management for Future Hardware

The goals of the DFG priority program on Scalable Data Management for Future Hardware (SPP2037) are based on the observation that data management architectures will undergo a radical shift in the next years. This is driven by the fact that on the one hand, the range of applications requiring to handle large sets of data has significantly broadened, and on the other hand, new trends in hardware as well as at operating system level offer great opportunities for rethinking current system architectures. The priority program is coordinated by Kai-Uwe Sattler (TU Ilmenau), Alfons Kemper, Thomas Neumann (TU Munich), and Jens Teubner (TU Dortmund).

Hybrid Transactional/Analytical Graph Processing in Modern Memory Hierarchies

Funding: DFG as part of SPP 2037

Today’s enterprise computing architectures are characterized by a complex memory hierarchy: the different application requirements in terms of latency, bandwidth, persistence, and access pattern as well as the characteristics of available memory and storage technology require combining different technologies.

Building highly efficient data management and analytics solutions which meet the challenges of modern applications requires to utilize this memory hierarchy, e.g. by caching strategies, taking the specific characteristics of a given technology into account, and keeping data objects in the optimal level. In this project, we plan to exploit modern memory hierarchies to support Hybrid transactional/analytical processing (HTAP) on graph data.

Asked & Answered: Intelligent Data Analysis in Software Projects

Funding: DFG

Software and systems engineering projects accumulate a mass of data in the form of domain documents, requirements, safety analysis, design, code, test cases, simulations, version control data, fault logs, model checkers, project plans and so on. When combined with the power of software analytics, this data can deliver the precise answers to questions that stakeholders demand. In particular, it can support decision making, process improvement, safety analysis, and a myriad of other software engineering tasks.

reDesigN - Resilience By Design for IoT Platforms in Distributed Energy Management

Funding: BMBF

In energy management system, reliability of information is important as it is needed for the optimal energy supply.Therefore, the main goal is to implement a distributed data processing pipeline that continuously adapts its behaviour to the changing environmental conditions due to threats and error conditions. In the context of energy management, fail-safe and resilient IoT platforms are necessary for the distributed energy management. Already there are different approaches to handle the errors in the data processing pipeline. However, additional costs such as runtime and overhead are imposed for the development and operation of these approaches.Therefore, a secure, cost- and runtime-efficient implementation must be defined.

The project reDesigN is a joint project with the project partners TU Ilmenau, Fraunhofer IOSB-AST, CUCULUS GmbH and HKW Elektronik GmbH. This project mainly consists of following tasks,

  • The analysis of the attack and failure scenarios in IoT systems.
  • Development of data management centered resilience strategies.
  • Define test scenarios based on identified attack and failure scenarios.
  • Development of an evaluation and simulation environment for failure scenarios.

This project is funded by the BMBF.

Readying VectorH for the Cloud

Funding: Actian

The project is a joint project with Actian, who develops the distributed database management system Actian Avalanche next do different solutions for data management, data integration and data analysis. Avalanche relies on VectorH as the underlying distributed data technology, which was developed for on-premise cluster environments. The main target of the project is to optimize Avalanche for the cloud environment, which especially contains two major aspects. On the one hand, approaches to optimize the system's architecture for the new hardware environment are investigated to exploit all opportunities the cloud environment offers. On the other hand, the system is driven in the direction of self-managing databases to increase it's ease-of-use and reduce the effort for administration and running a database.

Learning Products – Machine Learning Strategies for Intelligent Products in Medical Technology

Funding: Thüringer Ministerium für Wirtschaft, Wissenschaft und Digitale Gesellschaft

In the project "Learning Products" the TU Ilmenau and the FSU Jena are developing methods for intelligent suggestion and decision systems that support and monitor the operation of medical technology devices and the evaluation of their measurement results. LearningProducts is a joint project of the Software Engineering for Safety-Critical Systems Group, the Biomedical Engineering Group, and the Databases and Information Systems Group of the TU Ilmenau as well as the Computer Vision Group of the FSU Jena.

For the integration of machine learning methods into medical technology products, the project focuses on the following tasks:

  • Development and evaluation of centralized and distributed training and inference topologies
  • Development of an evaluation approach for training data and annotations
  • Development of methods and systems for secure and efficient transfer, storage and management of machine learning artifacts (datasets, models, and metadata)
  • Investigation of compatibility of machine learning with development and privacy requirements
  • Development of methods for the explainability of classification results
  • Prototypical implementation and studies with Thuringian companies

MemWerk - Memristive Materials for Neuromorphic Electronics

Funding: Carl-Zeiss-Stiftung

The MemWerk project is an interdisciplinary project in partnership with other research groups of TU Ilmenau. It aims at comprehensively investigating memristive materials for neuromorphic electronics, i.e., electronics inspired by biology, which are highly energy-efficient. Our goal is the management and analysis of complex material science data from the MemWerk project as graph data. We first develop a material atlas for collecting material and process parameters. Further, we model and manage the data as graph data and carry out graph analytics to gain insights into the material and process parameters concerning the characteristics and performance parameters of memristive devices and neuromorphic circuits. Thus, we can explore and extract information with regards to the material or process parameter(s) that will likely influence certain neuromorphic properties, the interplay that can be inferred between process components and measurements, the extent to which components are densely/loosely connected in a process, the parameters that are most central or important in certain processes, the parameters that play similar roles in the processes, the outlier measurements of parameters and/or neuromorphic properties etc. Ultimately, this would enable the realization of materials that are well-suited for neuromorphic systems.
