MAXIMUS-384
Core42 runs Maximus, an AMD Instinct MI300-based AI cluster at the Lake Mariner site in Buffalo, New York, serving hyperscale, AI-native and enterprise customers for frontier model training and fast inference.
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 compute for hyperscale, AI-native and large enterprise customers: frontier model training and high-speed inference 3
- Power design Facility power, energy supply or heat reuse as stated by the operator. Not the benchmark power in the Power column.
- Lake Mariner site expanding from 18 MW to 60 MW 3
- Facility Building, data centre or campus that houses the system, as described by the operator.
- Lake Mariner site, Buffalo, New York 3
- Upgrade or successor Announced upgrade, expansion, successor or retirement plan, with dates where the operator gives them.
- Core42 announced in June 2026 an expansion at the Buffalo site adding 42 MW and new NVIDIA and AMD capacity alongside Maximus 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.
- 24 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.
- 114.5 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 251.15 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 45.6 1
- Site Host or operator named by TOP500 for the installation.
- Maximus 1
- Country Country or region reported by TOP500 for the site.
- United States 1
- Region World region of the installation country (grouping applied by this site).
- Americas 1
- Vendor Manufacturer or system supplier exactly as submitted to TOP500.
- DELL 1
- Vendor group Supplier grouped for filtering. Bull is the Eviden/Atos line; Other covers single-system suppliers.
