Miyabi-G
Supermicro ARS 111GL DNHR LCC HPC system supplied by Fujitsu for Joint Center for Advanced High Performance Computing in Japan. The cited June 2026 TOP500 configuration delivers 46.80 PFLOP/s on HPL.
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.
- 52 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.
- 46.8 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 72.8 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 64.3 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.
- 983 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.
- 47.61 1
- Site Host or operator named by TOP500 for the installation.
- Joint Center for Advanced High Performance Computing 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.
- Fujitsu 1
- Vendor group Supplier grouped for filtering. Bull is the Eviden/Atos line; Other covers single-system suppliers.
- Fujitsu 1
- System model Hardware platform in the cited TOP500 edition.
- Supermicro ARS 111GL DNHR LCC 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- Grace Hopper Superchip 72C 3GHz 1
- Accelerator vendor Maker of the accelerator. None listed means TOP500 names no accelerator for the system.
- None listed 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.
- 221,952 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.
- 2026-06 1
- OS Operating system from the TOP500 system record.
