Summary
👤
Senior🎓
Top SchoolGabor Dozsa is a Senior Software Engineer with over a decade of experience designing high-performance parallel and distributed systems, currently based in Barcelona and working at IBM. He brings deep expertise in HPC, MPI, and multi-/many-core architectures from roles at ARM Research, Barcelona Supercomputing Center, and IBM Research, paired with production engineering experience at Volta Networks. Gabor has a PhD in Computer Science and a long research-to-production trajectory that blends low-level systems programming with architecture design. An active contributor to the gem5 simulator, he implemented distributed-simulation features—enabling multi-gem5 runs and a distributed Ethernet link—that make large-scale computer-system experiments more realistic. Known for tackling complex parallelization and distribution challenges, he bridges academic rigor and pragmatic engineering to push simulation and system performance forward.

Contributions summary:Gabor implemented significant features related to distributed gem5 simulations, adding support for multi-gem5 runs and a distributed Ethernet link. This included modifications to core files, such as `multi_iface.cc` and `dist_iface.cc`, and the addition of a distributed Ethernet link device. The contributions also involved updates to configuration files, including `gem5-dist.sh` and the example big.LITTLE configuration, and the introduction of a pseudo instruction. These changes facilitate simulations of distributed systems within the gem5 architecture simulator.
