  @inproceedings{10.1145/3698783.3699378, abstract = {External fragmentation is becoming a serious problem again after paging temporarily solved it with its one-size-fits-all 4 KiB approach. The increasing adoption of mixed base, huge, and giant page sizes, DRAM energy-saving techniques, and memory disaggregation, necessitates a memory management system capable of handling larger entities in the range of multiple megabytes up to several gigabytes.A case study in Linux reveals that the operating system reasonably minimizes fragmentation up to huge page size, but falls short when it comes to larger granularities. Therefore, it requires much effort to entirely free a memory block for powering down or returning it to the memory provider; in some cases, this may be entirely impossible due to immovable kernel memory.Additionally, our analysis highlights that the page cache is responsible for a large share of memory usage, as it keeps all cached pages until memory pressure rises. This behavior originates from the outdated assumption that utilizing memory comes at no cost and, therefore, requires further investigation.}, address = {New York, NY, USA}, author = {Halbuer, Alexander and Ostapyshyn, Illia and Steiner, Lukas and Wrenger, Lars and Jung, Matthias and Dietrich, Christian and Lohmann, Daniel}, booktitle = {Proceedings of the 2nd Workshop on Disruptive Memory Systems}, keywords = {myown}, pages = {33–40}, publisher = {Association for Computing Machinery}, series = {DIMES '24}, title = {The New Costs of Physical Memory Fragmentation}, year = 2024 }

  @inbook{Carbonelli2024, abstract = {Quantum software is becoming a key enabler for applying quantum computing to industrial use cases. This poses challenges to quantum software engineering in providing efficient and effective means to develop such software. Eventually, this must be reliably achieved in time, on budget, and in quality, using sound and well-principled engineering approaches. Given that quantum computers are based on fundamentally different principles than classical machines, this raises the question if, how, and to what extent established techniques for systematically engineering software need to be adapted. In this chapter, we analyze three paradigmatic application scenarios for quantum software engineering from an industrial perspective. The respective use cases center around (1) optimization and quantum cloud services, (2) quantum simulation, and (3) embedded quantum computing. Our aim is to provide a concise overview of the current and future applications of quantum computing in diverse industrial settings. We derive presumed challenges for quantum software engineering and thus provide research directions for this emerging field.}, address = {Cham}, author = {Carbonelli, Cecilia and Felderer, Michael and Jung, Matthias and Lobe, Elisabeth and Lochau, Malte and Luber, Sebastian and Mauerer, Wolfgang and Ramler, Rudolf and Schaefer, Ina and Schroth, Christoph}, booktitle = {Quantum Software: Aspects of Theory and System Design}, editor = {Exman, Iaakov and P{\'e}rez-Castillo, Ricardo and Piattini, Mario and Felderer, Michael}, keywords = {myown}, pages = {311–335}, publisher = {Springer Nature Switzerland}, title = {Challenges for Quantum Software Engineering: An Industrial Application Scenario Perspective}, year = 2024 }

  @article{benchi_24, abstract = {The slowdown of Moore’s Law necessitates an exploration of novel computing methodologies, new materials, and advantages in chip design. Thus, carbon-based materials have promise for more energy-efficient computing systems in the future. Moreover, sustainability emerges as a new concern for the semiconductor industry. The production and recycling processes associated with current chips present huge environmental challenges. Electronic waste is a major problem, and sustainable solutions in computing must be found. In this review, we examine an alternative chip design based on nanocellulose, which also features semiconductor properties and transistors. Our review highlights that nanocellulose (NC) is a versatile material and a high-potential composite, as it can be fabricated to gain suitable electronic and semiconducting properties. NC provides ideal support for ink-printed transistors and electronics, including green paper electronics. Here, we summarise various processing procedures for nanocellulose and describe the structure of exclusively nanocellulose-based transistors. Furthermore, we survey the recent scientific efforts in organic chip design and show how fully automated production of such a full NC chip could be achieved, including a Process Design Kit (PDK), expected variation models, and a standard cell library at the logic-gate level, where multiple transistors are connected to perform basic logic operations—for instance, the NOT-AND (NAND) gate. Taking all these attractive nanocellulose features into account, we envision how chips based on nanocellulose can be fabricated using Electronic Design Automation (EDA) tool chains.}, author = {Bencurova, Elena and Chinazzo, André and Kar, Bipasa and Jung, Matthias and Dandekar, Thomas}, journal = {Nanomaterials}, keywords = {myown}, number = 18, title = {How Far Is the Nanocellulose Chip and Its Production in Reach?

  @book{2024amateurfunklehrgang, abstract = {Willkommen in der faszinierenden Welt des Amateurfunks! Der Amateurfunkdienst bietet nicht nur die Möglichkeit zur persönlichen Wissenserweiterung durch Experimente und kontinuierliche Weiterbildung, sondern erlaubt auch, einen Beitrag zur globalen Verständigung zu leisten. Zudem kann der Amateurfunkdienst bei Hilfsaktionen in Not- und Katastrophenfällen unterstützen. Es ist wichtig zu betonen, dass der Amateurfunkdienst auf gleicher Ebene mit anderen Funkdiensten, wie zum Beispiel Mobilfunk, Rundfunk und Flugfunk, steht. Als Teilnehmer am Amateurfunkdienst besitzt man das Recht, eigene Sende- und Empfangsanlagen zu entwickeln und zu betreiben. Der Amateurfunk eröffnet die Möglichkeit, mit einer Vielzahl von Übertragungsverfahren zu experimentieren – von der klassischen Kurzwelle über Satellitenfunk bis hin zum Internet der Dinge, einschließlich neuer Verfahren mithilfe von künstlicher Intelligenz. Für die Teilnahme am Amateurfunkdienst ist ein Amateurfunkzeugnis erforderlich, das durch eine erfolgreiche Prüfung bei der Bundesnetzagentur erlangt wird. In Deutschland gliedert sich der Amateurfunk in drei Klassen: die Klasse N für Neueinsteiger, die erweiterte Klasse E und die Klasse A mit höchster Leistung auf allen zugeteilten Frequenzen. Diese Buchreihe dient der Vorbereitung auf die Prüfungen für die verschiedenen Amateurfunkklassen. Es ist zu beachten, dass die Prüflinge unterschiedliche Vorkenntnisse mitbringen. Für manche kann es ratsam sein, die Prüfungen für die verschiedenen Klassen in aufeinanderfolgender Reihenfolge abzulegen, während andere den direkten Weg zur Klasse A wählen. Einige finden im Selbststudium mit einem Buch oder einem Online-Kurs ausreichend Unterstützung, während andere einen Präsenzkurs oder einen persönlichen Ansprechpartner bevorzugen.

The idea of the transprecision computing is to consume adequate amount of energy for each operation by performing dynamic precision reduction. The impact of the memory subsystem plays a crucial role in such systems. Hence, the energy efficiency of a transprecision system can be further optimized by tailoring the memory subsystem to the transprecision computing. In this work, we present a lean, low power, low latency memory controller that is appropriate for transprecision methodology.

Despite the maturity of practices for designing and assessing architectures, as well as for virtual prototyping, it is still not clear how to jointly consider the practices from these disciplines within development processes, in order to address the dynamics imposed by continuous software engineering. In this regard, we discuss in this paper how to orchestrate architecture drivers and design specification techniques with virtual prototypes, to address the demands of continuous software engineering in development processes.

  @inproceedings{drotha_18, abstract = {Identifying and mitigating possible failure propagation from one safety-critical application to another through common infrastructural components is a challenging task. Examples of such dependencies across software-stack layers (e.g., between application and middleware layer) are common causes and failure propagation scenarios in which a failure of one software component propagates to another software component through shared services and/or common computational resources. To account for this, safety standards demand freedom from interference in order to control failure propagation between mixed-critical software components. Safety analysis is typically focused on one abstraction layer, while robustness tests try to find failure propagation paths across abstraction layers. To this end, this paper presents a model-based failure propagation analysis combining failure propagation within and across abstraction layers. A classification of dependencies in combination with fault trees is used to perform a model-based dependency analysis. In addition, a novel modeling technique for integrating failure propagation aspects resulting from shared services and resources is presented. The analysis was used to carry out an early safety assessment of a real-world automotive redundancy mechanism within an integrated architecture. The results show that the method improved reusability and modularity, and made it easier to estimate failure propagation issues, including possible violations of freedom from interference within an integrated system.}, address = {Cham}, author = {Dropmann, Christoph and Thaden, Eike and Trapp, Mario and Uecker, Denis and Amarnath, Rakshith and da Silva, Leandro Avila and Munk, Peter and Schweizer, Markus and Jung, Matthias and Adler, Rasmus}, booktitle = {Computer Safety, Reliability, and Security}, editor = {Gallina, Barbara and Skavhaug, Amund and Bitsch, Friedemann}, keywords = {myown}, pages = {73–87}, publisher = {Springer International Publishing}, title = {{A} {M}odel-{B}ased {S}afety {A}nalysis of {D}ependencies {A}cross {A}bstraction {L}ayers}, year = 2018 }

By exploiting the compute intensive execution stages of popular sequence analysis applications, we present and evaluate a VLSI architecture with a focus on those that target at biological sequences directly, including pairwise sequence alignment, multiple sequence alignment, database search, and short read sequence mappings. Based on coarse grained reconfigurable array we propose the use of many-core and 3D-stacked technologies to gain further improvement over memory subsystem, which gives another order of magnitude speedup from high bandwidth and low access latency. We analyze our approach in terms of its throughput and efficiency for different application mappings. Initial experimental results are evaluated from a stripped down implementation in a commodity FPGA, and then we scale the results to estimate the performance of our architecture with 9 layers of {\$}{\$}70 {\backslash}hbox {\{} mm{\}}^{\{}2{\}}{\$}{\$} 70 mm 2 stacked wafers in 45-nm process. We demonstrate numerous estimated speedups better than corresponding existed hardware accelerator platforms for at least 40 times for the entire range of applications and datasets of interest.

  @article{weimut_16, abstract = {In systems ranging from mobile devices to servers, DRAM has a big impact on performance and contributes a significant part of the total consumed power. The performance and power of the system depends on the architecture of the DRAM chip, the design of the memory controller and the access patterns received by the memory controller. Thus, evaluating the impact of DRAM design decisions requires a holistic approach that includes an appropriate model of the DRAM bank, a realistic controller and DRAM power model, and a representative workload, which requires a full system simulator running a complete software stack. In this paper, we introduce DRAMSpec, a high-level DRAM bank/chip modeling tool. Our contribution is to move the DRAM modeling abstraction level from the circuit level to the DRAM bank and by the integration in full system simulators we allow system or processor designers (non-DRAM experts) to tune future DRAM architectures for their target applications. We demonstrate the merits of DRAMSpec by exploring the influence of DRAM row-buffer (page) size and the number of banks on performance and power of a server application (memcached). Our new DRAM design offers a 16{\%} DRAM performance improvement and 13{\%} DRAM energy saving compared to standard comodity DDR3 devices. Additionally, we demonstrate how our tool is able to aid in evaluating novel DRAM architectures, such as the Hybrid Memory Cube (HMC), for which no DRAM datasheets are available. Finally, we highlight the DRAM technology scaling for a specific HMC architecture and we quantify the impact on latency and power.}, author = {Weis, Christian and Mutaal, Abdul and Naji, Omar and Jung, Matthias and Hansson, Andreas and Wehn, Norbert}, journal = {International Journal of Parallel Programming}, keywords = {myown}, month = 12, number = 6, pages = {1566–1591}, title = {{DRAMS}pec: {A} {H}igh-{L}evel {DRAM} {T}iming, {P}ower and {A}rea {E}xploration {T}ool}, volume = 45, year = 2017 }

  @article{junwei_15a, abstract = {Abstract 3D stacking of silicon dies via Through Silicon Vias (TSVs) is an emerging technology to increase performance, energy efficiency and integration density of today's and future System-on-Chips (SoCs). Especially the stacking of Wide I/O \{DRAMs\} on top of a logic die is a very promising approach to tackle the memory wall and energy efficiency challenge. The potential of this type of stacking is currently under investigation by many research groups and companies in particular for mobile devices. There, for instance, the baseband processing and the application processor can be implemented on the same single logic die. On top of this die one or several Wide I/O \{DRAMs\} are stacked. An example of such a SoC is the \{WIOMING\} chip [15]. However, new challenges emerge, especially thermal management, which is already a very demanding challenge in current 2D SoCs. With 3D SoCs this problem exacerbates due to reliability issues such as the temperature sensitivity of DRAMs, i.e., the retention time of a \{DRAM\} cell largely decreases with increasing temperature. In this paper, we show a holistic cross layer reliability approach for efficient reliability management starting from measuring and modeling of \{DRAM\} retention errors, which finally leads to optimizations for specific applications. These optimizations exploit the data lifetime and the inherent error resilience of the application, which is for instance given in the probabilistic behavior of wireless communications.}, author = {Jung, Matthias and Weis, Christian and Wehn, Norbert}, journal = {Microelectronics Reliability}, keywords = {DRAM}, note = {ICMAT 2015 Symposium}, pages = {43 - 47}, title = {{A} cross layer approach for efficient thermal management in 3{D} stacked {S}o{C}s}, volume = 61, year = 2016 }

Assembling of those short reads poses a challenge on the mapping of reads to a reference genome in terms of both sensitivity and execution time. In this paper, we propose a customized many-core hardware acceleration platform for short read mapping problems based on hash-index method. The processing core is highly customized to suite both 2-hit string matching and banded Smith-Waterman sequence alignment operations, while distributed memory interface with 3D–stacked architecture provides high bandwidth and low access latency for highly customized dataset partitioning and memory access scheduling. Conformal with original BFAST program, our design provides an amazingly 45,012 times speedup over software approach for single-end short reads and 21,102 times for paired-end short reads, while also beats similar single FPGA solution for 1466 times in case of single end reads.

In this work we propose a precisely tailored embedded architecture for com- puting similarities based on one special network motif, the co-occurrence. It is based on efficient and scalable building blocks that exploit well-tuned algorithmic refinements and an optimized graph data representation approach. On chip, our solution features a customized cache design and a light- weight data path that allows the system to perform over 10,000 graph operations per cycle on each chip. We provide detailed area, energy, and timing results for a 28 nm ASIC process and DDR3 memory devices.

Asset prices - and therefore the prices of all related financial products - change within several milliseconds nowadays. However, not only due to the financial crisis in 2008, calculating fair and meaningful prices for these products is much more important than in the past. In order to obtain reliable prices, sophisticated simulation models have to be used. Pricing in these models in general has a very high computational complexity and can in many cases only be approximately done by using numerical methods. On the other hand, we all know that energy costs will become more and more significant in the future. The gap between the increasing computational complexity and the consumed energy can only be bridged by using more tailored computation engines, like dedicated hardware accelerators or application specific instruction set processors (ASIPs). In this paper we present a comprehensive methodology for the efficient design of optimal hardware accelerators and the evaluation thereof. We give two case studies: a new hardware random number generator for arbitrary distributions and a dedicated hardware accelerator for calculating European barrier option prices.}, author = {de Schryver, Christian and Jung, Matthias and Wehn, Norbert and Marxen, Henning and Kostiuk, Anton and Korn, Ralf}, booktitle = {Knowledge-Based and Intelligent Information and Engineering Systems}, editor = {König, Andreas and Dengel, Andreas and Hinkelmann, Knut and Kise, Koichi and Howlett, Robert J. and Jain, Lakhmi C.}, keywords = {finance}, month = {09}, note = {Proceedings of 15th International Conference on Knowledge-Based and Intelligent Information \& Engineering Systems (KES)}, pages = {177–186}, publisher = {Springer Berlin Heidelberg}, series = {Lecture Notes in Computer Science}, title = {{E}nergy {E}fficient {A}cceleration and {E}valuation of {F}inancial {C}omputations towards {R}eal-{T}ime {P}ricing}, volume = 6884, year = 2011 }
