Beyond Thread States: Diagnosing Performance Degradation with eBPF and Thread Dynamics
Diogo Landau, Jorge G. Barbosa, Nishant Saurabh
Online Data-Intensive applications face performance degradation from load variability and resource interference. While Thread State Analysis (TSA) based approaches enable identifyi…
Hybrid Quantum-HPC Middleware Systems for Adaptive Resource, Workload and Task Management
Pradeep Mantha, Florian J. Kiwit, Nishant Saurabh +2
Hybrid quantum-classical applications pose significant resource management challenges due to heterogeneity and dynamism in both infrastructure and workloads. Quantum-HPC environmen…
Retrofitting Service Dependency Discovery in Distributed Systems
Diogo Landau, Gijs Blanken, Jorge Barbosa +1
Modern distributed systems rely on complex networks of interconnected services, creating direct or indirect dependencies that can propagate faults and cause cascading failures. To…
Collaborative State Machines: A Better Programming Model for the Cloud-Edge-IoT Continuum
Marlon Etheredge, Thomas Fahringer, Felix Erlacher +5
The development of Cloud-Edge-IoT applications requires robust programming models. Existing models often struggle to manage the dynamic and stateful nature of these applications ef…
Federated learning framework for collaborative remaining useful life prognostics: an aircraft engine case study
Diogo Landau, Ingeborg de Pater, Mihaela Mitici +1
Complex systems such as aircraft engines are continuously monitored by sensors. In predictive aircraft maintenance, the collected sensor measurements are used to estimate the healt…
Pilot-Quantum: A Quantum-HPC Middleware for Resource, Workload and Task Management
Pradeep Mantha, Florian J. Kiwit, Nishant Saurabh +2
As quantum hardware advances, integrating quantum processing units (QPUs) into HPC environments and managing diverse infrastructure and software stacks becomes increasingly essenti…
