Open Thesis Topics
Fixing Shortcomings of Kubernetes Severless TechnologiesApply
Serverless Computing or Function-as-a-Service (FaaS) has emerged as a new paradigm for computing over the last few years. There exists a number of open source FaaS platforms based on Kubernetes as the container orchestration platform maps well to the components required for FaaS. However, most approaches to FaaS are still relatively naive and leave many performance improvements on the table. This work focuses on said limitations and aims to solve at least one of them and implement a proof of concept. Finally, the performance improvements should be benchmarked in a virtualized environment and on the HPC system.
Confidential GPU InferenceApply
For customer facing systems that handle sensitve data such as patient information, it is required to comply with strict data protection laws. In order to comply with these laws even during a security breach, confidential computing should be used, however, modern use-cases require the usage of scable multi-user systems with GPU acceleration for ML inference workloads. This thesis encapsulates setting up confidential computing on top of a Kubernetes cluster using Kata Containers, Confidential Containers and Nvidia Confidential GPU Computing as well as measuring the performance costs of using a confidential compute stack.
Advancing Source References in RAG LLM SystemsApply
Retrieval-Augmented-Generation (RAG) is a method for providing an LLM with additional data via documents that are automatically added into queries. This method has been implemented in a number of ways including multiple open source projects such as PrivateGPT or H2OGPT. These projects commonly have a feature where the answer to a given query states what documents and what pages in these documents were used to complete the query, however, these can often be inaccurate as the system is forced to make a selection even in cases where no document has been used. For this thesis topic, a student would set up such a RAG LLM system and augment its retrieval system to provide more accurate references to documents or none if no documents from the given set were used.
