The BSC performance tools and their role in POP3 services
Code of the Month No 19 on 26.11.2025
Speaker: Marta Garcia.Gasulla, BSC
In this talk, Marta explores the performance-analysis ecosystem developed at BSC, featuring the Extae tracing framework, the Paraver visualization tool, and the TALP lightweight profiler. The talk introduces the core capabilities of each tool and demonstrate how, when used together, they provide deep insight into the behavior of HPC applications.
The presentartion then discusses how this toolset supports the performance services delivered to European HPC codes within the POP3 project. These services focus on large-scale applications and aim to identify key inefficiencies and bottlenecks that hinder parallel scalability. Through real examples, Marta shows how POP3 assessments guide developers toward more efficient and scalable execution on modern HPC architectures.
