From 7 to 9 October, the Barcelona Supercomputing Center-Centro Nacional de Supercomputación (BSC-CNS) celebrated its 6th MareNostrum Hackathon and ESiWACE3 was part of it. 

This two-day marathon is an opportunity for HPC application developers and users to deploy, test, port and optimise code on Europe's latest pre-exascale cluster. It helps HPC users develop, improve their applications and promotes innovation and technical excellence in HPC. Further, participants were able to access the resources of the general-purpose or GPU partition of the MareNostrum 5 supercomputer.

Our team from HPCW- The High Performance Climate&Weather Benchmark took part in the hackathon and used the opportunity to work on HPCW, a domain-specific benchmark that provides a set of relevant and realistic near-operational weather and climate workloads. 

Sergi Palomas, Research Engineer at BSC, was part of the team that participated in the hackathon and highlights the importance of being able to meet and work with the developers of HPCW in person: "A task that would have taken me weeks of work, they were able to do in a few hours. We were able to move almost all of HPCW to MN5, both the CPU (GP) and accelerator (APP) partitions. This has allowed us to obtain performance and energy metrics thanks to the tools we have here at BSC, and we have already started working on changes and improvements to HPCW that will allow these metrics to be collected automatically."

This year's MareNostrum Hackathon broke a record for participation, with 20 teams representing projects and other Centres of Excellence such as Plasma-PEPSC, POP, SPACE and others.
