The Swiss supercomputer Alps, developed by CSCS, stands out with a sixth place in the TOP500 ranking. While its PreAlps testing infrastructure ranks among the best in energy efficiency.

The Swiss supercomputer Alps, from the National Center for Scientific Computing (CSCS), rose to sixth place in the TOP500 ranking (63rd edition), which ranks supercomputers from around the world. With a power of 270 PFlop/s, Alps is the only newcomer in the top 10. Frontier, in the United States, remains the most powerful system with 1,206 EFlop/s, closely followed by Aurora. LUMI, with its 380 PFlop/s, stands out as the most powerful in Europe.

Another Swiss supercomputer, PreAlps, ranks fifth in the GREEN500, a ranking that evaluates the energy efficiency of high-performance computing (HPC) infrastructures. PreAlps has an efficiency of 64,381 GFlops/watts. The first place in GREEN500 is taken by JEDI – JUPITER Exascale Development Instrument, Germany, which achieved a power efficiency of 72.73 GFlops/Watts.

With five systems considered to be supercomputers, Switzerland ranks 18th in the world, far behind the United States (1st, with 171 systems) and China (2nd with 80 systems).

In project for several years at CSCS in Lugano, Alps also stands out as the first infrastructure to accommodate Grace Hopper CPUs from Nvidia. Contacted by ICTjournal, Mark Klein, systems architect at CSCS, explains that PreAlps is the test environment used for Alps. “During Alps’ Grace Hopper scaling phase that is currently happening, we are also using this infrastructure to test and validate new Grace Hopper hardware as it arrives to limit the impact on Alps’ existing vClusters. Alps,” specifies the engineer. Before adding that the specifications and technical capabilities of PreAlps are likely to evolve.
