Debrecen2 (Leo) was one of the first supercomputers in Hungary, for which a separate building was constructed for.. In the architecturally unique machine room, the HP SL250s (Debrecen2) and HP Apollo 8000 (Debrecen3) type machines, which were handed over in 2015, jointly use the 500 TB capacity Luster file system. Following the development of acceleration technology, Debrecen2 (Leo) was equipped with 204 NVIDIA k20x and 48 NVIDIA k40x graphics accelerator processors. Communication is provided by a low-latency InfiniBand connection.
