A paper accepted at SEC 2026
Our paper “Occamy: Latency-Aware Scheduling with Controlled Degradation for Mixed-Criticality AI at the Edge”, in collaboration with Patient, has been accepted as a full paper at SEC 2026.
We extend the graceful-degradation methodology of Cerberus from latency relaxation to model-variant selection through the development of the Occamy global scheduling model, targeting mixed-criticality AI inference across distributed edge sites. Whereas Cerberus restores feasibility by relaxing the latency bounds of low-criticality applications, Occamy exploits the multiple model variants that AI applications expose, each trading inference accuracy for lower latency and resource consumption. Occamy predicts the P99 end-to-end latency of a candidate deployment and jointly selects a model variant, an instance count, and a user-to-site assignment for each application under strict per-application SLOs and edge capacity limits. Under resource scarcity, a priority-aware degradation algorithm switches low-criticality applications to lighter variants in controlled steps until a feasible placement is found, while preserving the nominal quality of high-criticality ones. This delivers graceful degradation along the accuracy dimension, keeping all applications operational with quality loss that is predictable and minimal.
Yinan will present the paper during the conference on October 13-16 2026 in Santa Clara, CA, United States.

A paper accepted at VISSOFT 2026
The paper “Visualizing the Evolution of Data Access in Microservices” has been accepted to VISSOFT 2026 in the Research track.
In this work, we argue that existing visualizations of microservices primarily focus on structural and behavioral perspectives, leaving a gap in the analysis of changes across versions. To address this limitation, we introduce a set of novel visualizations and metrics that can be combined to support evolutionary analyses of microservices. Among these, we introduce the Comparison Treemap, the Difference Treemap, and the Evolutionary Treemap. These build upon the contributions we presented last year at the same venue. We evaluate our approach on 42 evolution scenarios using historical data from 10 real-world software systems, totaling 5 million lines of code.
Maxime will present this paper with his co-authors early September 2026 in Benevento (Italy).
The paper was co-authored with Prof. Massimiliano Di Penta from the University of Sannio (Italy).

The paper “Cerberus: Latency-Aware Scheduling with Graceful Degradation for Constrained Edge Infrastructures” has been accepted at SRDS 2026 as a full paper.
We extend the scheduling methodology of Scylla to handle multi-application concurrency under resource scarcity on edge clusters through the development of the Cerberus global scheduling model. Recognizing that edge resources are finite and may be insufficient to simultaneously satisfy all application SLOs under peak demand, Cerberus extends latency-aware scheduling with a graceful degradation mechanism that avoids the service disruptions caused by eviction-based strategies. Instead of dropping low-criticality applications, Cerberus introduces the concept of a Service Level Threshold (SLT), which bounds the maximum acceptable performance degradation for each application, and a priority-aware degradation algorithm that progressively relaxes the latency bounds of low-criticality applications in controlled steps until a feasible placement is found, while preserving strict SLO compliance for high-criticality ones. This ensures that all applications remain operational under resource scarcity, with degradation that is predictable, minimal, and proportional to application criticality.

The paper “Scylla: Scheduling Multiple Latency-Sensitive Applications in the Edge-Cloud Continuum” has been accepted at IWQoS 2026 as a regular paper in the Edge-Cloud Resource Allocation track.
We extend the scheduling methodology of LASSY to handle multi-application concurrency through the development of the Scylla global scheduling model. Recognizing that edge nodes are rarely dedicated to a single task, Scylla generalizes the single-application formulation to jointly schedule multiple co-located applications competing for shared resources across the edge-cloud continuum, mitigating the “Noisy Neighbor” effect through a holistic deployment plan that ensures all applications meet their respective SLOs without mutual performance interference. As the joint optimization of multiple applications causes the problem scale and computation time to grow rapidly, we further introduce the Layered Permutation Search (LPS) heuristic, which decomposes the global problem into a sequence of single-application problems and explores application orderings at controllable depth, achieving near-optimal placement plans within practical time limits even for large numbers of applications.
Yinan will present the paper during the conference during June 29 - July 2 2026 in Istanbul, Turkey.
