NIPA(NHN Cloud)-CL-2
NHN Cloud runs Korea's largest B200 GPU fleet, about 4,000 GPUs linked as a single cluster, to train very large AI models, drawing on its experience operating a national AI data centre.
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.
- Training very large AI models and large-scale parallel computation 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.
- 40 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.
- 68.42 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 77.94 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 87.8 1
- Site Host or operator named by TOP500 for the installation.
- NHN Cloud 1
- Country Country or region reported by TOP500 for the site.
- South Korea 1
- Region World region of the installation country (grouping applied by this site).
- Asia-Pacific 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 ProLiant Compute XD685 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- AMD EPYC 9365 36C 3.4GHz 1
- Accelerator Accelerator model listed for the system. Empty when TOP500 lists none.
- NVIDIA B200 1
- Accelerator vendor Maker of the accelerator. None listed means TOP500 names no accelerator for the system.

- Infiniband NDR400 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.
- 320,280 1
- Installed Installation year reported in the TOP500 system record. Not necessarily the year of production acceptance.
- 2026 2
- Edition TOP500 edition (YYYY-MM) that supplies the ranking and benchmark data. A historic edition does not assert current operating status.
