This is the 60th edition of the TOP500.
The Frontier system at the Oak Ridge National Laboratory, Tennessee, USA remains the No. 1 system on the TOP500 and is still the only system reported with an HPL performance exceeding one Exaflop/s. Frontier brought the pole position back to the USA on the June listing with an HPL score of 1.102 Exaflop/s.
With an HPL score of 1.102 EFlop/s, the Frontier machine at Oak Ridge National Laboratory (ORNL) did not improve upon the score it reached on the June 2022 list. That said, Frontier’s near-tripling of the HPL score received by second-place winner is still a major victory for computer science. On top of that, Frontier demonstrated a score of 7.94 EFlop/s on the HPL-MxP benchmark, which measure performance for mixed precision calculation. Frontier is based on the HPE Cray EX235a architecture and it relies on AMD EPYC 64C 2GHz processor. The system has 8,730,112 cores and a power efficiency rating of 52.23 gigaflops/watt. It also relies on gigabit ethernet for data transfer.
The top position was previously held for two years straight by the Fugaku system at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan. With its HPL benchmark score of 442 Pflop/s, Fugaku is now listed as No. 2.
The LUMI system at EuroHPC/CSC in Finland entered the list last June at No. 3. It is again listed as No. 3 but only thanks to an upgrade of the system, which doubled its size. With its increased HPL score of 309 Pflop/s it remains the largest system in Europe.
The only new machine to grace the top of the list was the No. 4 Leonardo system at EuroHPC/CINECA in Bologna, Italy. The machine achieved an HPL score of .174 EFlop/s with 1,463,616 cores.
Here a brief summary of the system in the Top10:
Frontier is the No. 1 system in the TOP500. This HPE Cray EX system is the first US system with a performance exceeding one Exaflop/s. It is installed at the Oak Ridge National Laboratory (ORNL) in Tennessee, USA, where it is operated for the Department of Energy (DOE). It currently has achieved 1.102 Exaflop/s using 8,730,112 cores. The new HPE Cray EX architecture combines 3rd Gen AMD EPYC™ CPUs optimized for HPC and AI, with AMD Instinct™ 250X accelerators, and Slingshot-10 interconnect.
Fugaku now the No. 2 system is installed at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan. It has 7,630,848 cores which allowed it to achieve an HPL benchmark score of 442 Pflop/s.
The upgraded LUMI system, another HPE Cray EX system installed at EuroHPC center at CSC in Finland is the No. 3 with a performance of 309.1 Pflop/s. The European High-Performance Computing Joint Undertaking (EuroHPC JU) is pooling European resources to develop top-of-the-range Exascale supercomputers for processing big data. One of the pan-European pre-Exascale supercomputers, LUMI, is located in CSC’s data center in Kajaani, Finland.
The new No. 4 system Leonardo is installed at a different EuroHPC site in CINECA, Italy. It is an Atos BullSequana XH2000 system with Xeon Platinum 8358 32C 2.6GHz as main processors, NVIDIA A100 SXM4 40 GB as accelerators, and Quad-rail NVIDIA HDR100 Infiniband as interconnect. It achieved a Linpack performance of 174.7 Pflop/s.
Summit, an IBM-built system at the Oak Ridge National Laboratory (ORNL) in Tennessee, USA, is now listed at the No. 5 spot worldwide with a performance of 148.8 Pflop/s on the HPL benchmark, which is used to rank the TOP500 list. Summit has 4,356 nodes, each one housing two Power9 CPUs with 22 cores each and six NVIDIA Tesla V100 GPUs each with 80 streaming multiprocessors (SM). The nodes are linked together with a Mellanox dual-rail EDR InfiniBand network.
A total of 179 systems on the list are using accelerator/co-processor technology, up from 169 six months ago. 64 of these use NVIDIA Ampere chips, 1 use 18, and 84 systems with NVIDIA Volta.
Intel continues to provide the processors for the largest share (75.80 percent) of TOP500 systems, down from 77.60 % six months ago. 101 (20.20 %) of the systems in the current list used AMD processors, up from 18.60 % six months ago.
The entry level to the list moved up to the 1.73 Pflop/s mark on the Linpack benchmark.
The last system on the newest list was listed at position 460 in the previous TOP500.
Total combined performance of all 500 exceeded the Exaflop barrier with now 4.86 exaflop/s (Eflop/s) up from 4.40 exaflop/s (Eflop/s) 6 months ago.
The entry point for the TOP100 increased to 5.78 Pflop/s.
The average concurrency level in the TOP500 is 189,586 cores per system up from 182,864 six months ago.
The system to claim the No. 1 spot for the GREEN500 is Henri at Flatiron Institute in the US. With 5920 total cores and an HPL benchmark of 2.04 PFlop/s. Henri is a Lenovo ThinkSystem SR670 wih Intel Xeon Platinum and Nvidia H100.
In the second place is the Frontier Test & Development System (TDS) at ORNL in the US. With 120,832 total cores and an HPL benchmark of 19.2 PFlop/s, the Frontier TDS machine is basically just one rack identical to the the actual Frontier system.
The No. 3 spot was taken by the Adastra system. A HPE Cray EX235a system with AMD EPYC and AMD Instinct MI250X.
Supercomputer Fugaku remains the leader on the HPCG benchmark with 16 PFlop/s.
The DOE system Frontier at ORNL claims the second position with 14.05 HPCG-Pflop/s.
The third position was captured by the upgraded LUMI system with 3.40 HPCG-petaflops.
On the HPL-MxP (formally HPL-AI) benchmark, which measures performance for mixed precision calculation, Frontier already demonstrated 6.86 Exaflops! The HPL-MxP benchmark seeks to highlight the use of mixed precision computations. Traditional HPC uses 64-bit floating point computations. Today we see hardware with various levels of floating point precisions, 32-bit, 16-bit, and even 8-bit. The HPL-MxP benchmark demonstrates that by using mixed precision during the computation much higher performance is possible (see the Top 5 from the HPL-MxP benchmark), and using mathematical techniques, the same accuracy can be computed with the mixed precision technique when compared with straight 64-bit precision.

The first version of what became today’s TOP500 list started as an exercise for a small conference in Germany in June 1993. Out of curiosity, the authors decided to revisit the list in November 1993 to see how things had changed. About that time they realized they might be onto something and decided to continue compiling the list, which is now a much-anticipated, much-watched and much-debated twice-yearly event.
