Iacovos Kolokasis from FORTH presented their work-in-progress paper “SmartSweep” at MPLR 2025!  Big data frameworks (e.g., Spark, Neo4j) often extend the JVM heap into remote memory, but GC in this setting is a nightmare: high network traffic, delayed reclamation, and nasty OOM errors. 💡 SmartSweep tackles this head-on:⚡ Dual-heap design with approximate liveness info 🗑️ Selective reclamation of garbage-heavy regions — no scanning, no compaction 📉 Cuts remote...

Thanos Stratikopoulos from UNIMAN presented on 14th of October TornadoInsight at MPLR 2025, which was co-located with SPLASH!  TornadoInsight is an open-source IntelliJ IDEA plugin that streamlines development with TornadoVM by detecting incompatible Java constructs and providing immediate, source-linked feedback. By bridging the gap between Java’s high-level abstractions and low-level accelerator programming, TornadoInsight helps developers boost productivity, simplify debugging, and build more efficient applications for heterogeneous computing systems....

On 14th of October, Michalis Papadimitriou from UNIMAN, presented their work on TornadoViz at MPLR 2025, which was co-located with SPLASH!  TornadoViz is a visual analytics tool that brings transparency to heterogeneous execution in Java applications. By leveraging TornadoVM’s specialized bytecode system, it bridges the gap between high-level application logic and low-level hardware behavior. With TornadoViz, developers can interactively explore task dependencies, memory operations, and performance bottlenecks across...
