There is also a new first place in the person of El Capitan, and the top four places are held by the United States.
A top500.org has updated the ranking of supercomputers in the world, and we can also welcome a new king at the top of the podium. Specifically, the US-designed El Capitan system was deployed, which currently consists of 11,136 HPE Cray EX255a nodes, each of which uses 4 AMD Instinct MI300A APUs. With this system, we cannot therefore speak of CPU and GPU in the classical sense, but rather of CPU and GPU chiplets, which are located on common housings and share the system memory in a coherent manner. This offers much simpler programmability, as memory copies between the host CPU and the accelerator can be avoided. El Capitan’s maximum theoretical performance with its current design reaches 2746.3 PFLOPS, of which it achieves 1742 PFLOPS in the Linpack test, and this is coupled with a consumption of 29.58 megawatts.
Frontier, which was considered the previous leader, slipped to second place, but it has expanded a little since the middle of the year, so the maximum speed of the new hardware configuration is 2055.7 PFLOPS, and it can show 1353 PFLOPS in the Linpack test, with a consumption of 24.6 megawatts.
The third and fourth positions were taken by Aurora and Eagle, which have not changed in recent months, and the fifth place was taken by the new, Italian-built system called HPC6, which uses HPE Cray EX235a nodes also used by Frontier. With 64-core AMD EPYC processors and AMD Instinct MI250X accelerators. This system is capable of 477.9 PFLOPS in the Linpack test, out of a theoretical 606.97 PFLOPS, while requiring roughly 8.46 megawatts.
The sixth position was taken by Supercomputer Fugaku, but Alps became stronger, so it only slipped back to seventh place, ahead of LUMI, which was considered even stronger in the middle of the year, which was good for eighth place without modifications. By the way, Alps’ new build is capable of 434.9 PFLOPS of the theoretical 574.8 PFLOPS in the Linpack test, while it requires roughly 7.1 megawatts. The ninth place was taken by the previously seventh Leonardo, which was also unchanged.
The top ten is rounded off by Tuolumne, built in the USA, which is actually considered the test system of the new flagship El Capitan, so it uses the same configuration, only in a much smaller size. Thanks to this, its maximum speed is 288.88 PFLOPS, and of this it brings 208.1 PFLOPS in the Linpack test, with a consumption of 3.387 megawatts. In practice, we have achieved that the most powerful machine is so muscular that even its test design is suitable for entering the top ten, which clearly shows how wide open the scissors are even among the best.
