41st POP Webinar – From Code to Scale: EPICURE’s Services, Stories, and Training for EuroHPC Users
João Barbosa introduced EPICURE’s free high-level support services for EuroHPC users, explaining how researchers can access expert assistance with code enabling, scalability, performance analysis, benchmarking, and optimisation to improve the performance of applications on European supercomputers. It also showcased real-world success stories across scientific domains and highlighted the European HPC Application Support Portal as a resource for training materials, best practices, code examples, and guidance on applying for EPICURE support.

42nd POP Webinar - A Compiler-Assisted Workflow for Efficiency-Guided Selective Tracing
This webinar presented a compiler-assisted workflow for efficiency-guided selective tracing, enabling scalable HPC performance analysis with much lower tracing overhead. Using a two-stage profiling and tracing approach, the method achieved a 10× reduction in trace size while preserving key performance insights in a 500-node Vlasiator case study.

POP @ NHR PerfLab Seminar: The MAQAO performance analysis and optimization framework
On March 10, 2026, POP experts William Jalby and Cédric Valensi presented MAQAO as part of the NHR PerfLab seminar events. They showed how the MAQAO performance analysis and optimisation framework combines static and dynamic analysis, sampling, tracing and simulation to identify HPC bottlenecks and guide developers towards the most effective code optimisations.
You can find the slides and recording here.
POP @ NHR PerfLab Seminar: MERIC: Energy Efficiency Data Center Software Suite
On May 5, 2026, POP expert Ondřej Vysocký presented MERIC as part of the NHR PerfLab seminar events. He demonstrated tools for monitoring and optimising power and energy consumption in HPC systems through cluster monitoring, job energy budgeting and runtime tuning.

Apply For Free Help with Code Optimisation
We offer a range of free services designed to help EU organisations improve the performance of parallel software. If you are not getting the performance you need from parallel software or would like to review the performance of a parallel code, please apply for help via the short Service Request Form, or email us to discuss the service further and how it can be beneficial.
These services are funded by the EuroHPC research and innovation programme so there is no direct cost to our users.
The POP Helpdesk
Past and present POP users are eligible to use our email helpdesk. Please contact our team of experts for help analysing code changes, to discuss your next steps and to ask questions about your parallel performance optimisation.
