Leonardo
Leonardo is a EuroHPC pre-exascale supercomputer hosted and run by CINECA at the Bologna Technopole, serving European research and industry in AI, data analytics, medicine, energy, climate and agriculture.
What it runs and how to get time
From the operator- Used for What the operator says the system is used for: science domains, missions or workloads. Taken from the operator, its funder or the system vendor, not from TOP500.
- AI and machine learning, high-performance data analytics and simulation for medicine, energy, climate and agriculture; the LISA partition targets LLM and multimodal AI training. 4
- How to get time How researchers or customers get time on the system, naming the allocation programme where the operator states one.
- Half of Leonardo's resources go to European users through open, peer-reviewed EuroHPC JU Access Calls. 4
- Cooling Cooling design stated by the operator or supplier.
- Water-cooled system. 4
- Power design Facility power, energy supply or heat reuse as stated by the operator. Not the benchmark power in the Power column.
- Power consumption can be adjusted dynamically to balance energy saving against performance. 4
- Facility Building, data centre or campus that houses the system, as described by the operator.
- CINECA data centre at the Bologna Technopole (Tecnopolo), Bologna, Italy. 4
- Upgrade or successor Announced upgrade, expansion, successor or retirement plan, with dates where the operator gives them.
- LISA upgrade (EUR 50M, Bull) adds an AI partition of 166 eight-GPU servers (1,328 GPUs); inaugurated 11 June 2026, open to users from summer 2026. 5
Benchmark and hardware
Source per value- Rank Position in the TOP500 edition named in the Edition column. Historic systems keep the rank of the edition where they last appeared.
- 12 1
- Rmax PFLOP/s Measured double-precision LINPACK (HPL) performance of the listed configuration. Older TFLOP/s and GFLOP/s figures are converted to PFLOP/s.
- 241.2 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 306.31 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 78.7 1
- Power kW Power reported for the benchmark run. Measurement boundaries vary by site; this is not facility power, TDP or cooling capacity. Empty when the system does not report it.
- 7,494 1
- Efficiency GFLOP/s per W Rmax per watt of reported benchmark power, computed from the two sourced figures (GFLOP/s per W). Empty when power is not reported.
- 32.19 1
- Site Host or operator named by TOP500 for the installation.
- EuroHPC/CINECA 1
- Country Country or region reported by TOP500 for the site.
- Italy 1
- City Site city as reported by TOP500 or the operator. It can be the operator address rather than the machine room.
- Bologna 3
- Region World region of the installation country (grouping applied by this site).
- Europe 1
- Vendor Manufacturer or system supplier exactly as submitted to TOP500.
- Bull 1
- Vendor group Supplier grouped for filtering. Bull is the Eviden/Atos line; Other covers single-system suppliers.
- Bull 1
- System model Hardware platform in the cited TOP500 edition.
- BullSequana XH2000 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- Xeon Platinum 8358 32C 2.6GHz 1
- Accelerator Accelerator model listed for the system. Empty when TOP500 lists none.
- NVIDIA A100 SXM4 64 GB 1
- Accelerator vendor Maker of the accelerator. None listed means TOP500 names no accelerator for the system.
- NVIDIA 1
- Interconnect Network fabric exactly as listed in the cited TOP500 edition.
- Quad-rail NVIDIA HDR100 Infiniband 1
- Fabric Interconnect family derived from the listed interconnect (grouping applied by this site).
- InfiniBand 1
- Cores cores Total cores submitted to TOP500, including accelerator cores where TOP500 counts them. Not a CPU-only count and not a CUDA-core count.
- 1,824,768 1
- Installed Installation year reported in the TOP500 system record. Not necessarily the year of production acceptance.
- 2023 2
- Edition TOP500 edition (YYYY-MM) that supplies the ranking and benchmark data. A historic edition does not assert current operating status.
