ABCI 3.0
ABCI 3.0 is AIST's AI Bridging Cloud Infrastructure, operated by AIST Solutions at Kashiwa as an open platform for Japanese industry, academia, government and startups to develop generative AI.
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 R&D and evaluation, sovereign AI and LLM development, AI startup support and workforce development for Japanese industry, academia and government. 4
- How to get time How researchers or customers get time on the system, naming the allocation programme where the operator states one.
- Paid public use for domestic industry, academia, government, universities and startups via an application procedure, plus Development Acceleration Use and LLM support. 4
- Cooling Cooling design stated by the operator or supplier.
- Hybrid hot-water and air cooling, 70 kW per rack, cutting cooling power. 4
- Power design Facility power, energy supply or heat reuse as stated by the operator. Not the benchmark power in the Power column.
- AI Data Center upgraded for ABCI 3.0 to 6 MW electrical and 5.2 MW cooling capacity across 144 racks. 5
- Facility Building, data centre or campus that houses the system, as described by the operator.
- AI Data Center, AIST Kashiwa Center, University of Tokyo Kashiwa II Campus, Kashiwa, Japan. 4
- Production start Month the operator says the system entered production.

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.
- 19 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.
- 145.1 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 181.49 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 79.9 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.
- 3,596 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.
- 40.35 1
- Site Host or operator named by TOP500 for the installation.
- National Institute of Advanced Industrial Science and Technology (AIST) 1
- Country Country or region reported by TOP500 for the site.
- Japan 1
- City Site city as reported by TOP500 or the operator. It can be the operator address rather than the machine room.
- Kashiwa 3
- 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 Cray XD670 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- Xeon Platinum 8558 48C 2.1GHz 1
- 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 NDR200 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.
- 479,232 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.
