Internships at CSCS - the Swiss National Supercomputing Centre 2025

The Swiss National Supercomputing Centre (CSCS) develops and operates cutting-edge, high-performance computing (HPC) systems as an essential service facility for science. The centre enables world-class research through its scientific user lab, which is available to domestic and international researchers in academia, industry, and the business sector. The centre is operated by ETH Zurich and has offices in Lugano (headquarters) and Zurich.

Leveraging Retrieval-Augmented Generation with LLMs for Accurate Responses from Corporate Documentation.

The Swiss National Supercomputing Centre (CSCS) provides high-performance computing services for Swiss researchers, supporting activities from high-resolution simulations to complex data analysis. To maintain quality and continuity of services, CSCS manages extensive documentation in Confluence, with a publicly accessible section known as the Knowledge Base, and problem-solving knowledge in Jira Service Desk. This project aims to leverage Large Language Models (LLM) and Retrieval-Augmented Generation (RAG) technologies to develop a chatbot service that delivers answers based on CSCS documentation. The service will be initially designed for internal use at CSCS. The work involves setting up state of the art pre-trained LLMs for efficient inference, ingesting data from Confluence and Jira, and integrating components into a web- or Slack-based chatbot. The minimum criterion for success is the development of a service capable of accurately retrieving and providing links to relevant Confluence pages and Jira issues based on user queries. A more advanced measure of success would be the chatbot's ability to generate precise, contextually relevant answers to queries, beyond simply returning links, thereby enhancing the overall user experience.    

Although the project centers around using LLMs, the ideal candidate should have a strong focus and interest in system engineering. The work will require a solid knowledge of Python and Linux, deploying pre-trained LLMs, running them on Kubernetes (k8s) or SLURM clusters, and interacting with Confluence and Jira. The candidate should be independent, motivated, and eager to work in a flexible, international environment.

Requirements

Skills

• solid knowledge of Python and Linux
• independence and motivation
• problem-solving
• knowledge of HPC system is beneficial
• basic understanding of LLM is beneficial 
• system engineering skills are beneficial

Enhancing an Internal Development Platform with Automation and Monitoring

The Swiss National Supercomputing Centre (CSCS) develops and operates a high-performance computing and data research infrastructure that supports world-class science in Switzerland. To achieve this mission, multiple specialized engineering teams must collaborate effectively, utilizing a dynamic set of processes and tools for developing and operating their solutions. For effective collaboration, an integrated and harmonized Software Development Lifecycle (SDLC)—covering planning, documentation, coding, building, testing, and monitoring—is essential. The platform team responsible for core SDLC services at the center is seeking a motivated intern to join them.

The selected candidate will have the opportunity to make tangible improvements to CSCS's internal development platform. Working alongside experienced system administrators and software engineers, the intern will gain hands-on experience with automation, CI/CD pipelines, containerized deployments, observability, and best practices in DevOps. The goal of the internship is to create a monitoring dashboard that meets the operational needs of the platform team by integrating essential information from tools such as Jira, Confluence, GitLab, JFrog, and Vault. This work will involve centralizing logging and automating validations to report on key metrics. At least one DORA metric should be included, with additional metrics to be defined based on the candidate's interests.

Requirements

• Skills
  • Linux and git experience
  • Scripting languages (e.g. Bash or Python)
  • REST APIs familiarity
  • Problem decomposition
  • Good communication skills
• Beneficial Skills:
  • CI-CD pipelines
  • Automated testing
  • Linux containers and their orchestration
  • Monitoring frameworks

Add support for profiling CUDA workloads to Tracy

Tracy is an open source tool for profiling and performance analysys, originally designed for video game development . To see a presentation of Tracy in action, have a look at this talk from cppcon .

It has been widely adopted in other performance-sensitive fields, such as high-frequency trading, because of its responsive user interface, ease of use and low overheads. Tracy currently supports profiling of graphics APIs (DirectX, Vulkan, etc), and has a well-defined interface for adding support for additional GPU backends.

The focus of this internship would be to add support for profiling HPC and ML/AI workloads that use CUDA, by adding a new GPU back end to Tracy. At the end of the internship, we will aim to demonstrate Tracy working for GH200 system Alps. The plugin will be published as an open source extension, that we will try to have upstreamed to the main tracy code.

There is one main goal, and some optional stretch goals that would depend on the length of the internship and the interests of the applicant.

• main goal: add support for CUDA tracing of based on the existing Vulkan back end using the CUPTI library.
• stretch goal: add support for automatic tracing of kernel and memory transfers.
• stretch goal: investigate MPI support.
• stretch goal: add AMD GPU support.

Requirements

• Skills
  • C/C++/Rust familiarity is required, and an interest in low-level programming.
  • Experience GPU programming would be beneficial, but it is not a hard requirement.
