POP Webinars
Recent Webinars
36th POP Webinar – Scalable Visualization of Nsight Systems Traces with Paraver
An increasing use of GPUs and new parallelisation strategies and communication libraries in HPC environments require us to revise our performance analysis tools and methodologies. On the 10th of October Marc Clascà Ramírez showed us how additional performance insight can be gained from Nvidia nsys traces with Paraver.

37th POP Webinar – Exploring Compiler Behavior on Applications from Miniapp up to Large-scale Application on Modern Processors
On the 5th of November William Jalby demonstrated how MAQAO (www.maqao.org) coupled with QaaS (https://www.compqual.org/qaas_page/) can be used to explore and detect compiler mistakes or suboptimal decisions, helping the user select the best compiler strategy.

38th POP Webinar – Levels of Detail in Performance Analysis
On the 18th of December Jesús Labarta discussed the importance of performance analysis tools and methodologies. He demonstrated how to minimize the number of measurement experiments needed while maximizing the insight gained.

POP @ EuroHPC User Days 2025
From the 30th of September to the 1st of October HPC experts came together in Copenhagen, Denmark, for the EuroHPC User Days 2025. POP experts Marta Garcia and Marta Garcia-Gasulla (BSC) and Ricardo Nobre (INESC-ID) were in Denmark to represent the POP Consortium informing users what POP can do for them.

Analysing HIP codes with Extrae and Paraver
This article shows that Extrae now supports the GPU programming model HIP — enabling GPU-accelerated codes to be traced without special recompilation or linking.
By analysing these traces with Paraver, developers can visualise GPU kernels, host-device interactions and resource usage, helping to pinpoint performance bottlenecks in heterogeneous CPU-GPU applications.

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.
