Nano 4
Taiwan's National Center for High-performance Computing runs Nano 4, part of the Chip Innovation 26 sovereign AI system, for generative AI training and inference, climate simulation, life sciences, semiconductor R&D and smart manufacturing.
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.
- Generative AI model training and inference, HPC for semiconductors, biomedicine, climate simulation, digital twins and smart manufacturing 3
- How to get time How researchers or customers get time on the system, naming the allocation programme where the operator states one.
- Academia, government and industry apply for compute through NCHC's iService portal; paid service from July 2026 after a free June trial 3
- Cooling Cooling design stated by the operator or supplier.
- Direct liquid cooling (DLC) 4
- Power design Facility power, energy supply or heat reuse as stated by the operator. Not the benchmark power in the Power column.
- System PUE 1.18; host centre has 14.99 MW capacity, 2N power, 5.4 MW backup generator and a Silver green building label 4
- Facility Building, data centre or campus that houses the system, as described by the operator.
- NCHC Cloud Computing Center, Southern Taiwan Science Park, Xinshi District, Tainan 5
- Upgrade or successor Announced upgrade, expansion, successor or retirement plan, with dates where the operator gives them.
- Two GB200 NVL72 systems added to the Chip Innovation 26 platform, open for free trial use from 1 September 2026 5
- Production start Month the operator says the system entered production.
- 2026-06 3
- Status Operating status, filled only when the operator states it.
- In production 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.
- 33 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.
- 81.55 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 117.92 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 69.2 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.
- 2,214 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.
- 36.83 1
- Site Host or operator named by TOP500 for the installation.
- National Center for High Performance Computing 1
- Country Country or region reported by TOP500 for the site.
- Taiwan 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.
- ASUSTeK / Taiwan AI Cloud / Taiwan Mobile 1
- Vendor group Supplier grouped for filtering. Bull is the Eviden/Atos line; Other covers single-system suppliers.
- Other 1
- System model Hardware platform in the cited TOP500 edition.
- ASUS ESC N8-E11V 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.

- Accelerator Accelerator model listed for the system. Empty when TOP500 lists none.
- NVIDIA H200 SXM5 141 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.
- 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.
- 256,960 1
- Installed Installation year reported in the TOP500 system record. Not necessarily the year of production acceptance.
- 2025 2
- Edition TOP500 edition (YYYY-MM) that supplies the ranking and benchmark data. A historic edition does not assert current operating status.
