Your function

The AtLarge research group [https://atlarge-research.com/] at the Department of Computer Science at VU Amsterdam invites applications for two PhD positions, fully funded for 4 years each, in the context of a national-scale 6G Future Networked Services (FNS) project. The two PhD candidates will pursue research within the large, long-term, national project FNS, and be embedded in the AtLarge research team focusing on Massivizing Computer Systems, that is, designing, building, deploying, testing, benchmarking, analyzing, and optimizing large-scale distributed systems, and supporting a variety of applications in AI, big data, scientific computing, and business-critical workloads.

These positions provide an excellent opportunity to develop deep expertise in modern systems while tackling real-world challenges that span software, hardware, and large-scale complex software ecosystems. Concretely, the two positions provide each with a unique opportunity (1) to pursue research aligned with the group's research interests, toward a modern software and hardware infrastructure that supports 21st-century societal needs funded by the FNS project until 2030 and beyond by other projects in the team, (2) to integrate into a large local team and with international partners, and (3) to identify and pursue high-quality scientific research across areas of computer systems, including but not limited to:

Systems across the digital continuum, cloud datacenter, edge, endpoint, 6G;
Distributed systems and cluster management (e.g., orchestration with Kubernetes), and general management and scheduling techniques (e.g., workflow management, for serverless);
High-performance computing and hardware/software acceleration (e.g., GPUs, NPUs, FPGAs);
Systems, programming models, and runtimes for scientific and high-performance computing;
Runtime systems, compilers, and programming language technologies (e.g., language VMs);
Large-scale data analytics and stream processing systems;
Digital twins and system-scale simulation;
Systems for virtual worlds, interactive experiences in modifiable virtual worlds;
Cloud computing and mobile networking (e.g., 6G networking);
AI for Systems and Systems for AI – applied across all the other topics listed here, and beyond;
Emerging computing paradigms and technologies (e.g., Operational Data Analytics, new serverless beyond FaaS, WebAssembly, disaggregated resources, sustainable computing beyond energy-use reduction, ML accelerators used also for HPC);
More topics in designing, building, deploying, testing, benchmarking, experimenting with, evaluating, analyzing, and optimizing large-scale software and hardware systems.

Key Responsibilities

Design computer systems and implement prototypes that address research questions at any/all levels of modern software and hardware ecosystems;
Design, conduct, and analyze experiments to evaluate system properties such as performance, scalability, reliability, sustainability, and cost-efficiency across various platforms and workloads;
Conduct reproducible and open-science compliant research, ensuring that code, data, other artifacts, and experimental results are well-documented and publicly shareable when appropriate, aiming to receive the relevant reproducibility badges from ACM and IEEE;
Develop and/or extend tools and frameworks for monitoring, benchmarking, tuning, and modeling and simulation of distributed and large-scale systems;
Participate in the research-oriented education processes our team and Department are conducting, e.g., through supervision of Honours Programme, BSc, and MSc research projects;
Contribute to our unique training sessions, which our team has pioneered in the Netherlands, and that help develop tens of young researchers each year;
Collaborate with faculty, postdocs, and fellow PhD students to integrate insights across multiple research areas, including networking, runtime systems, high-performance computing, and data-intensive infrastructures, and across the Department of Computer Science at the VU;
Engage in international collaborations and research visits, facilitated by our research team or on your own, to expand the reach and network for your research;
Disseminate research outcomes through publications in top-tier conferences and journals, and select contributions on early ideas to workshops, informing professionals through tutorials and demos, and in general presenting scientific and technical results to the international community.
