Communication Collectives for the Cerebras Wafer-Scale Engine
(2023)Cerebras Wafer-Scale Engine (WSE) is a powerful architecture used initially for machine learning training but now also for a larger variety of workloads. To achieve the best possible performance on the hardware it is crucial to have efficient reduce and allreduce communication collectives. We therefore provide the first systematic investigation of the reduce operation on the Cerebras WSE using the Cerebras SDK. The provided implementations ...Bachelor Thesis -
Performance Trade-offs Analysis of SmartNIC Architectures
(2023)In-network packet processing utilizing SmartNICs has emerged as a promising method for enhancing the performance of distributed applications. This approach leverages packet-level parallelism and aligns with the in-network computing trend, which involves integrating energy-efficient processing cores with high-speed NICs. By offloading specific data processing tasks to the networking infrastructure instead of relying solely on the Host CPU, ...Bachelor Thesis -
Designing of a communication library for Versal devices using Stream-Based API
(2023)The Versal Adaptive Compute Acceleration Platform is a programmable heterogeneous device that combines general-purpose CPU cores, pro- grammable logic, and specialized AI Engine compute processors in the same System-on-Chip. Versal devices are starting to be shipped in the market, and how to efficiently program and leverage them are still open questions. Max Wierse’s Bachelor Thesis [10] already provides a starting point to reason about ...Bachelor Thesis -
Boot Firmware for Heterogeneous Systems running Linux
(2023)The primary role of the boot firmware is to initialize essential system components before booting an operating system. At the same time, it should provide hardware descriptions and interaction mechanism through the UEFI and ACPI standards. The current boot firmware for Enzian is unmaintainable due to its outdated design and reliance on an obsolete EDK2 version, without any obvious way to update it. Consequently, a complete rewrite ...Bachelor Thesis -
Trusted Firmware for a Research Computer
(2023)Firmware plays a crucial role in the boot process of every computer. However, firmware stacks often suffer from issues related to their size and complexity, typically stemming from years of patchwork to support new platforms or fix bugs. This thesis delves into the realm of firmware by rewriting the initial stage of the firmware stack of the Enzian research computer. The emphasis of this study is on understanding and optimizing the ...Bachelor Thesis -
Sustainability Narratives of Swiss Coffee Roasters
(2023)Coffee roasteries are important stakeholders in the coffee value chain, notably regarding their action towards sustainability which is needed in the context of climate change and the current issues in the structure of the coffee value chain. As Switzerland is one of the top exporters of roasted and processed coffee worldwide, roasters in the country have a significant influence on the sustainability of the coffee value chain. This bachelor ...Bachelor Thesis -
Comparison of Electoral Systems and Optimization of Voting Advice Questionnaires
(2023)Our work is divided into three parts. In the first chapters, we simulate and compare different electoral systems using the 2019 Swiss parliamentary elections smartvote dataset. The results show that the dataset is strongly homogeneous, with little to no cantonal differences in terms of political views and election outcomes. The second part focuses on modeling an election with election trees. In particular, we define and model the Candidate ...Bachelor Thesis -
Development, Assembly and Testing of a Power Supply System for a Hyperloop Prototype
(2023)This thesis presents the development of an advanced battery system within Swissloop’s continuous efforts to advance Hyperloop technology. For the 2023 prototype, several innovations were introduced, including a new Double Sided Reluctance Motor and levitation system. These additions necessitated the creation of a new power supply system capable of meeting their energy requirements. To fulfill these demands, custom-made Lithium Polymer ...Bachelor Thesis -
Mapping RO observations using different ML algorithms
(2023)Through Global Navigation Satellite Systems (GNSS) Radio occultation (RO), the bending of radio signals due to their refractions while passing through earth’s atmosphere can be measured using Low Earth Orbit satellites. The refractivities determined with such measurements are crucial in the creation of Numerical Weather Models (NWM), which are used to display the atmosphere’s temperature, pressure, and humidity. Due to the sparse and ...Bachelor Thesis -
Experimentelle Validierung eines Georeferenzierungssystem für ein helikoptergestütztes Bodenradarsystem
(2023)Diese Bachelorarbeit befasst sich mit der Weiterentwicklung des an der ETH Zürich entwickelten Airborne Ice Radar Systems (AIR-ETH), einem Messsystem zur genauen Bestimmung der Gletschermächtigkeit. Das AIR-ETH liefert georeferenzierte Daten als Helikopter-gestütztes Bodenradarsystem. Diese Bachelorarbeit baut auf der Arbeit von Lardon (2022) auf. Insbesondere wird die Implementierung des auf Sensorfusion basierenden Georeferenzierungssystems ...Bachelor Thesis
