From 2 to 4 November 2021 the 3rd MareNostrum Hackathon (MNHACK21) was held online with a total of five teams and sixteen participants. The aim of this event (included in the BSCTech Hackathons 2021 series) was to help optimize applications using various programming models (such as OpenMP, OmpSs, MPI, CUDA, OpenACC, Parallelware and HIP, among others). The EPEEC project sponsored the event that was organized by the Barcelona Supercomputing Center (BSC), in collaboration with the HPC center of excellence PoP.
During the hackathon, participants, BSC mentors and experts interacted greatly, sharing key ideas to the related topics. Mentors from different scientific areas, including computer and application scientists, helped participants accomplish their purposes through live hacking and problem-solving.
"Our BSC mentor has been instrumental in achieving our goals: helping set up the application and run scalability tests."
The teams were reviewed and selected specially by the BSC, so mentors and developers could take the most advantage out of the 30-hour hackathon. During this time, developers received help in optimizing their codes and analyzing their performance. People participating in the event were from the domains of linear algebra, materials modeling at nanoscale, nanophotonics and nanoplasmonics and compressible reactive multiphase flows.
The participants from MNHACK21 came from the following European institutions: Cineca, Pázmány Péter Catholic University (Faculty of Information Technology and Bionics), IMEC and Inria. BSC, Universitat Politecnica de Catalunya (UPC). All of them found the hackathon to be very fruitful and would like to come back for a 2022 edition, that is expected to take place in late October to early November 2022.
