The upcoming Code of the Month event, set for 26 November 2025, is organized by the European HPC Joint Undertaking ecosystem in collaboration with the POP3 Centre of Excellence (CoE). It will highlight cutting-edge performance analysis tools developed at the Barcelona Supercomputing Center, such as the Extae tracing framework, the Paraver visualization tool, and the TALP lightweight profiler. These tools deliver in-depth insights into HPC application performance and are employed by POP3 to offer performance services for large-scale European HPC applications.
