The 63rd edition of the TOP500 reveals that Frontier has once again claimed the top spot, despite no longer being the only exascale machine on the list. Additionally, a new system has found its way into the Top 10.

The Frontier system at Oak Ridge National Laboratory in Tennessee, USA remains the most powerful system on the list with an HPL score of 1.206 EFlop/s. The system has a total of 8,699,904 combined CPU and GPU cores, an HPE Cray EX architecture that combines 3rd Gen AMD EPYC CPUs optimized for HPC and AI with AMD Instinct MI250X accelerators, and it relies on Cray's Slingshot 11 network for data transfer. On top of that, this machine has an impressive power efficiency rating of 52.93 GFlops/Watt - putting Frontier at the No. 13 spot on the GREEN500.

Increasing its HPL score from 1.02 Eflop/s in November 2022 to an impressive 1.194 Eflop/s on this list, Frontier was able to improve upon its score after a stagnation between June 2022 and November 2022. Considering exascale was only a goal to aspire to just a few years ago, a roughly 17% increase here is an enormous success. Additionally, Frontier earned a score of 9.95 Eflop/s on the HLP-MxP benchmark, which measures performance for mixed-precision calculation. This is also an increase over the 7.94 EFlop/s that the system achieved on the previous list and nearly 10 times more powerful than the machine's HPL score. Frontier is based on the HPE Cray EX235a architecture and utilizes AMD EPYC 64C 2 GHz processors. It also has 8,699,904 cores and an incredible energy efficiency rating of 52.59 Gflops/watt. It also relies on gigabit ethernet for data transfer.

IBM today revealed the next generation of its IBM POWER central processing unit (CPU) family: IBM POWER10. Designed to offer a platform to meet the unique needs of enterprise hybrid cloud computing, the IBM POWER10 processor uses a design focused on energy efficiency and performance in a 7 nm form factor with an expected improvement of up to 3x greater processor energy efficiency, workload capacity, and container density than the IBM POWER9 processor.

Designed over five years with hundreds of new and pending patents, the IBM POWER10 processor is an important evolution in IBM's roadmap for POWER. Systems taking advantage of IBM POWER10 are expected to be available in the second half of 2021. Some of the new processor innovations include:

IBM today unveiled its next-generation Power Systems Servers incorporating its newly designed POWER9 processor. Built specifically for compute-intensive AI workloads, the new POWER9 systems are capable of improving the training times of deep learning frameworks by nearly 4x allowing enterprises to build more accurate AI applications, faster.

The new POWER9-based AC922 Power Systems are the first to embed PCI-Express 4.0, next-generation NVIDIA NVLink and OpenCAPI, which combined can accelerate data movement, calculated at 9.5x faster than PCI-E 3.0 based x86 systems. The system was designed to drive demonstrable performance improvements across popular AI frameworks such as Chainer, TensorFlow and Caffe, as well as accelerated databases such as Kinetica. As a result, data scientists can build applications faster, ranging from deep learning insights in scientific research, real-time fraud detection and credit risk analysis.

China has been increasingly - and steadily - gaining relevance in the supercomputing world, with most of the top-500 entries being controlled by that country. In fact, China can boast of having the number one supercomputer in the world, the Sunway TaihuLight, which can deliver 93 PetaFLOPS of computing power - just 3x more computational power than the second most powerful machine, China's own Tianhe-2). However, supercomputing, and the amount of money that's earned by selling processing slices of these supercomputers for private or state contractors, i a very attractive pull - especially considering the increasingly more expensive computational needs of the modern world.

The Summit is to be the United State's call to fame in that regard, bringing the country back to number one in raw, top-of-the-line single-machine supercomputing power. Summit is promising to more than double the PetaFLOPS of China's TaihuLight, to over 200 PetaFLOPs. That amounts to around 11x more processing grunt than its predecessor, the Titan, in a much smaller footprint - the Titan's 18,688 processing nodes will be condensed to just ~4,600 nodes on the Summit, with each node achieving around 40 TeraFLOPS of computing power. The hardware? IBM and NVIDIA, married in water-cooled nodes with the powerful GV100 accelerator that's still eluding us enthusiasts - but that's a question for another day.
