POP Webinars
Upcoming Event
28th POP Webinar - The CARM Tool: Cache-aware Roofline Model for HPC
Join us on the 5th of September
In this live webinar, José Morgado (INESC-ID) will present the Cache-aware Roofline Model (CARM) which offers effective guidance by providing insights into bottlenecks that limit the application’s ability to reach the system’s maximum performance. Additionally, this webinar will include a live demonstration of the capabilities of this tool including a short tutorial of its usage.
Past Events
Last webinar: Performance Analysis of OpenMP Target Offloading in Score-P
On Ap 30, 2024, Jan Andre Reuter (JSC) presented first results in adding support for OpenMP offloading to the JSC instrumentation and measurement infrastructure Score-P using the OpenMP Tools Interface. The recording and the slide presentation can be found here.

Recent POP Events
POP @ Durham Performance Analysis Workshop Series 2024
POP successfully participated and contributed to the Performance Analysis Workshop Series 2024, which was organised by DiRAC High Performance Computing facility and Durham University and ran from the 4th of April until the 9th of May.
Read our blog article for more on the workshop and POP’s contribution.
POP @ ISC 2024
POP was represented by several of our experts and partners at this year’s ISC in Hamburg from the 12th of May to the 16th of May. Our contributions included an introductory presentation about POP3 at the EuroHPC JU booth, presentations for workshop as well as the organisation of workshops and tutorials. Our POP experts were also represented at booths for the various project partners.

POP @ HPCSE24
The High Performance Computing in Science and Engineering 2024 conference organised by IT4Innovations National Supercomputing Center in the Besydy mountains of the Czech Republic was attended by three of our POP experts.

POP @ 45th VI-HPS Tuning Workshop
Instructors from the POP partners BSC, JSC and UVSQ supported the 45th VI-HPS Tuning Workshop, which took place at the Leibniz Supercomputing Centre in Garching, Germany, from the 10th to 13th of June 2024.

POP Tool Descriptions
RWTH Performance and Correctness Tools
The IT Center of the RWTH Aachen University develops the correctness analysis tools MUST and Archer and the performance analysis tool OTF-CPT. Archer is a dynamic data race detector for OpenMP programs which identifies data races in large OpenMP applications with low runtime and memory overheads. MUST is a runtime error detection tool for MPI applications. It detects usage errors of the MPI at runtime and reports them to the user. And OTF-CPT is a lightweight performance analysis tool that reports a summary of POP metrics for MPI+OpenMP at the end of execution.
Find out more about the tool here.
Inesc-ID Tools and Methods
The Cache-aware Roofline Model (CARM), developed at the CHAMP Hub at INESC-ID, is an insightful computer architecture performance model. It offers a high-level picture on the fundamental memory and compute performance limitations, while also providing intuitive analysis of the application execution bottlenecks and effectively guiding optimization efforts. The CARM Tool [2] provides a one-stop shop for CARM related analysis across a variety of different architectures, supporting nearly all major CPU vendors and ISAs.

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.
