HPC6
Eni runs HPC6 in its Green Data Center near Milan to optimise plants, study CO2 storage, develop batteries, biofuels and biochemistry materials and simulate fusion plasma, and shares it with outside innovators.
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.
- Plant optimisation, CO2 storage studies, battery and biochemistry materials, biofuel supply chain, magnetic-confinement fusion plasma simulation 3
- How to get time How researchers or customers get time on the system, naming the allocation programme where the operator states one.
- Eni's own use; external access through the Call4Innovators programme and, since July 2026, project partnerships via Eni AI services 4
- Cooling Cooling design stated by the operator or supplier.
- Direct liquid cooling dissipating 96% of generated heat, in a new liquid-cooled area of the data center 3
- Power design Facility power, energy supply or heat reuse as stated by the operator. Not the benchmark power in the Power column.
- Maximum consumption 10.17 MVA 3
- Facility Building, data centre or campus that houses the system, as described by the operator.
- Eni Green Data Center, Ferrera Erbognone near Milan (Pavia), Italy, in a dedicated area 3
- Upgrade or successor Announced upgrade, expansion, successor or retirement plan, with dates where the operator gives them.
- Joined by HPC7 in June 2026; together the two systems exceed 1 exaflop/s sustained 4
- Production start Month the operator says the system entered production.
- 2024-11 3
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.
- 8 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.
- 477.9 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 606.97 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.
- 8,461 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.
- 56.48 1
- Site Host or operator named by TOP500 for the installation.
- Eni S.p.A. 1
- Country Country or region reported by TOP500 for the site.
- Italy 1
- Region World region of the installation country (grouping applied by this site).
- Europe 1
- Vendor Manufacturer or system supplier exactly as submitted to TOP500.
- HPE 1
- Vendor group Supplier grouped for filtering. Bull is the Eviden/Atos line; Other covers single-system suppliers.
- HPE 1
- System model Hardware platform in the cited TOP500 edition.
- HPE Cray EX235a 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- AMD Optimized 3rd Generation EPYC 64C 2GHz 1
- Accelerator Accelerator model listed for the system. Empty when TOP500 lists none.
- AMD Instinct MI250X 1
- Accelerator vendor Maker of the accelerator. None listed means TOP500 names no accelerator for the system.
- AMD 1
- Interconnect Network fabric exactly as listed in the cited TOP500 edition.
- Slingshot-11 1
- Fabric Interconnect family derived from the listed interconnect (grouping applied by this site).
- Slingshot 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.
- 3,143,520 1
- Installed Installation year reported in the TOP500 system record. Not necessarily the year of production acceptance.
- 2024 2
- Edition TOP500 edition (YYYY-MM) that supplies the ranking and benchmark data. A historic edition does not assert current operating status.
