This work describes the recovery workflow, the remote-pipe data path, the distributed file reader, and the executor-side optimizations that keep fault-tolerance overhead low on the common path of F RACTAL, a system for fault-tolerant distributed execution of unmodified POSIX shell scripts.
Coarse-grained reconfigurable architectures (CGRAs) promise high energy efficiency but remain vulnerable to transient upsets and aging-induced defects. We introduce a compiler-transparent reliability framework that provides online error detection and fast in-field recovery without requiring remapping or software checkp...
Fugue is a novel, self-contained reactive protocol that provides seamless and resource-efficient elasticity and reaches comparable handover performance while avoiding continuous replication overhead, and is implemented in Apache Flink.

While serverless computing is popular, its dominant Function-as-a-Service (FaaS) model is ill-suited for stream processing because its stateless, centrally orchestrated functions cannot efficiently handle continuous, low-latency event flows. We introduce Epico, a serverless runtime explicitly designed to resolve these...

The transition of Java applications from monolithic, bare-metal enterprise deployments to cloud-native, containerized environments (e.g., Kubernetes) has introduced severe memory management challenges. Traditional Java Virtual Machine (JVM) heuristics—designed for high-throughput, multi-gigabyte monolithic runtimes—oft...

This paper presents Ouros, a pipelined processor for lazy functional programming languages based on combinator graph reduction. Ouros overcomes the inherent sequentiality of graph reduction through dataflow-driven execution and automatic fine-grained multi-threading. It maintains pipeline utilisation by hiding per-thre...
