Enabling Multi-Dimensional Distributed Trace Comparison with Contrast
Vaastav Anand, Rodrigo Fonseca, Jonathan Mace +1
Diagnosis using distributed traces is fundamentally a comparative task: operators seek to understand how an anomalous execution differs from expected behavior, how a deployment cha…
Epistemic Observability in Language Models
Tony Mason, Vaastav Anand
We find that models report highest confidence precisely when they are fabricating. Across four model families (OLMo-3, Llama-3.1, Qwen3, Mistral), self-reported confidence inversel…
MAESTRO: Multi-Agent Evaluation Suite for Testing, Reliability, and Observability
Tie Ma, Yixi Chen, Vaastav Anand +8
We present MAESTRO, an evaluation suite for the testing, reliability, and observability of LLM-based MAS. MAESTRO standardizes MAS configuration and execution through a unified int…
SoK: Demystifying the multiverse of MPC protocols
Roberta De Viti, Vaastav Anand, Pierfrancesco Ingo +1
This paper systematizes knowledge on the performance of Multi-Party Computation (MPC) protocols. Despite strong privacy and correctness guarantees, MPC adoption in real-world appli…
DMAS-Forge: A Framework for Transparent Deployment of AI Applications as Distributed Systems
Alessandro Cornacchia, Vaastav Anand, Muhammad Bilal +2
Agentic AI applications increasingly rely on multiple agents with distinct roles, specialized tools, and access to memory layers to solve complex tasks -- closely resembling servic…
Iridescent: A Framework Enabling Online System Implementation Specialization
Vaastav Anand, Deepak Garg, Antoine Kaufmann
Specializing systems to specifics of the workload they serve and platform they are running on often significantly improves performance. However, specializing systems is difficult i…
Generating representative macrobenchmark microservice systems from distributed traces with Palette
Vaastav Anand, Matheus Stolet, Jonathan Mace +1
Microservices are the dominant design for developing cloud systems today. Advancements for microservice need to be evaluated in representative systems, e.g. with matching scale, to…
Intent-based System Design and Operation
Vaastav Anand, Yichen Li, Alok Gautam Kumbhare +6
Cloud systems are the backbone of today's computing industry. Yet, these systems remain complicated to design, build, operate, and improve. All these tasks require significant manu…
Towards Online Code Specialization of Systems
Vaastav Anand, Deepak Garg, Antoine Kaufmann
Specializing low-level systems to specifics of the workload they serve and platform they are running on often significantly improves performance. However, specializing systems is d…
Chatting with Logs: An exploratory study on Finetuning LLMs for LogQL
Vishwanath Seshagiri, Siddharth Balyan, Vaastav Anand +5
Logging is a critical function in modern distributed applications, but the lack of standardization in log query languages and formats creates significant challenges. Developers cur…
Columbo: Low Level End-to-End System Traces through Modular Full-System Simulation
Jakob Görgen, Vaastav Anand, Hejing Li +2
Fully understanding performance is a growing challenge when building next-generation cloud systems. Often these systems build on next-generation hardware, and evaluation in realist…
SoK: The Faults in our Graph Benchmarks
Puneet Mehrotra, Vaastav Anand, Daniel Margo +2
Graph-structured data is prevalent in domains such as social networks, financial transactions, brain networks, and protein interactions. As a result, the research community has pro…
HotOS XIX Panel Report: Panel on Future of Reproduction and Replication of Systems Research
Roberta De Viti, Solal Pirelli, Vaastav Anand
At HotOS XIX (2023), we organized a panel to discuss the future of reproducibility and replication in systems research. In this document, we highlight the key points and themes tha…
The Benefit of Hindsight: Tracing Edge-Cases in Distributed Systems
Lei Zhang, Vaastav Anand, Zhiqiang Xie +2
Today's distributed tracing frameworks are ill-equipped to troubleshoot rare edge-case requests. The crux of the problem is a trade-off between specificity and overhead. On the one…
Aggregate-Driven Trace Visualizations for Performance Debugging
Vaastav Anand, Matheus Stolet, Thomas Davidson +3
Performance issues in cloud systems are hard to debug. Distributed tracing is a widely adopted approach that gives engineers visibility into cloud systems. Existing trace analysis…
