Shaheen III - GPU
The KAUST Supercomputing Lab runs the GPU partition of Shaheen III, an HPE Cray EX system with 2,800 Grace Hopper superchips. It was the fastest supercomputer in the Middle East when installed and serves KAUST research projects.
What it runs and how to get time
From the operator- How to get time How researchers or customers get time on the system, naming the allocation programme where the operator states one.
- Project-based: a PI submits a development or production project proposal (production gets scientific and computational readiness review); outside organisations first file an Organisational Access Application 5
- Facility Building, data centre or campus that houses the system, as described by the operator.
- King Abdullah University of Science and Technology campus, Saudi Arabia 4
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.
- 22 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.
- 122.8 1
- Rpeak PFLOP/s Theoretical peak double-precision performance of the listed configuration. This is not AI or mixed-precision throughput.
- 155.21 1
- HPL efficiency % Rmax divided by Rpeak: the share of theoretical peak the system delivered on LINPACK. Computed from the two sourced figures.
- 79.1 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.
- 1,980 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.
- 62.02 1
- Site Host or operator named by TOP500 for the installation.
- King Abdullah University of Science and Technology 1
- Country Country or region reported by TOP500 for the site.
- Saudi Arabia 1
- City Site city as reported by TOP500 or the operator. It can be the operator address rather than the machine room.
- Jeddah 3
- Region World region of the installation country (grouping applied by this site).
- Middle East & Africa 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 EX254n 1
- Processor CPU description in the cited TOP500 edition; clock and core count refer to the processor model.
- NVIDIA Grace 72C 3.1GHz 1
- Accelerator Accelerator model listed for the system. Empty when TOP500 lists none.
- NVIDIA GH200 Superchip 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.
- Slingshot-11 1
- Fabric Interconnect family derived from the listed interconnect (grouping applied by this site).
- Slingshot 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.
- 574,464 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.
- 2026-06 1
- OS Operating system from the TOP500 system record.
- HPE Cray OS 2
