Started as my bachelor’s thesis: a ground-up redesign of an older lab tool that I rebuilt into what CRAB is now. It benchmarks HPC systems — interconnects, collectives, congestion behavior — and runs on Leonardo, one of the EuroHPC pre-exascale machines. Developed in the HLC Lab at Sapienza within the Net4Exa project. Current work: making it general-purpose enough to benchmark systems we haven’t met yet.
