PITAGORA
PITAGORA is the new Tier-1 system hosted by CINECA and fully dedicated to the EUROFusion community to conduct research on nuclear fusion. It replaces the former system MARCONI in the Casalecchio Headquarters.
Supplied by Lenovo Corp, it is composed by water cooled nodes divided in two partitions: a general purpose partition cpu-based named DCPG and an accelerated partition based on NVIDIA H100 accelerators named Booster.
