Success Story
From Performance Assessment to Faster Simulations:
Optimising Alya through POP3
Alya, developed at the Barcelona Supercomputing Center (BSC), is a high-performance computational mechanics code capable of solving complex, coupled-physics problems and is one of the codes included in the EXCELLERAT CoE.
In collaboration with EXCELLERAT POP has conducted a performance assessment of an Alya use case to analyse a combustion simulation. The simulation uses the external ISAT-CK7 library to accelerate the computation of chemical reactions by retrieving results from a previously computed table.

POP Webinars
Recent Webinars
43rd POP Webinar - Experiences of an HPC analyst in AI Land
Although deeply rooted in the HPC domain, the POP CoE has made efforts to apply HPC tools and methodologies to the AI world. In this talk POP expert Jesus Labarta (BSC) described his experiences of this transition and explained how POP has reached a point where it can carry out very detailed analyses of AI application execution and provide more insight into actual performance ('HPC performance') than application developers or users often have.

Upcoming Webinars
44th POP Webinar - Can our Scales Handle the Weight? Testing the POP Tools on Large Systems
In this live webinar, Valentin Seitz (BSC) will report on experiments with the POP tools at large scale on up to 112,000 CPU cores and 2,048 GPUs on MareNostrum 5 using two HPC applications that maintain a reasonable granularity at this scale. He will explore the overheads and costs of measuring applications at scale during data collection, post-processing and visualization.

Upcoming Events
POP @ ACM womENcourage 2026
On Oct 1, 2026, instructors from the POP partners Barcelona Supercomputing Center (BSC) and Jülich Supercomputing Centre (JSC) will present the tutorial “Introduction to High Performance Computing and Performance Metrics and Tools” at the ACM womENcourage 2026 conference in Sophia Antipolis, France.
Introduction and Coaching with POP Methodology and Tools
In cooperation with the Czech National Competence Centre in HPC POP experts will present the Introduction and Coaching with POP Methodology and Tools course, to be held on-site at IT4Innovations on Nov 4, 2026.
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.
