Observability and Fault Injection for LLM-Based Multi-Agent Systems in Software Engineering
Zahra Seyedghorban, Egor Klimov, Arie van Deursen +2
Large Language Model-based multi-agent systems are increasingly explored for software engineering tasks, but they remain difficult to inspect, debug, and evaluate under controlled…
TriCEGAR: A Trace-Driven Abstraction Mechanism for Agentic AI
Roham Koohestani, Ateş Görpelioğlu, Egor Klimov +2
Agentic AI systems act through tools and evolve their behavior over long, stochastic interaction traces. This setting complicates assurance, because behavior depends on nondetermin…
Balancing Fairness and Performance in Multi-User Spark Workloads with Dynamic Scheduling (extended version)
Dāvis Kažemaks, Laurens Versluis, Burcu Kulahcioglu Ozkan +1
Apache Spark is a widely adopted framework for large-scale data processing. However, in industrial analytics environments, Spark's built-in schedulers, such as FIFO and fair schedu…
Model-guided Fuzzing of Distributed Systems
Ege Berkay Gulcan, Burcu Kulahcioglu Ozkan, Rupak Majumdar +1
We present a coverage-guided testing algorithm for distributed systems implementations. Our main innovation is the use of an abstract formal model of the system that is used to def…
