Hewlett-Packard Enterprise maintains its traditional lead role on the latest Top 500 list with 123 installed supercomputers. However, that’s down from 144 systems six months ago.
China’s Lenovo follows HPE with 81 systems, down from 88. But the real surprise was in two second-tier suppliers in China who were the only ones to show growth in the latest rankings.
Inspur ranked third with 56 systems, up from only 20 six month ago. Sugon took fifth place behind Cray with 51, up from 44 in June. For its part, Huawei was responsible for 19 systems on the list
Inspur and Sugon were the only systems vendors to see their share of overall Top 500 performance rise. Inspur’s systems delivered 6.3 percent of the overall performance on the list while Sugon was responsible for 5.2 percent.
Cray and HPE continue to lead as the vendors delivering most performance overall at 19.5 ad 15.2 percent, respectively. A China integrator took third, thanks to its work on the TaihuLight system, and Lenovo was fourth at 9.1 percent.
In semiconductors, Intel continues to dominate the list with a continued strong showing by Nvidia in GPU accelerators.
A whopping 471 systems — 94.2 percent of the total — are now using Intel processors, up from 92.8 percent six months ago. Systems using IBM Power processors dropped to 14 from 21 in June.
The number of systems using some form of coprocessor rose to 101 from 91 six months ago. Nvidia continues to dominate this socket, with its GPUs used in 86 of the systems compared to just 12 using Intel’s Xeon Phi and five in Japan using Pezy Computing’s chips. Interestingly, 17 systems now use Xeon Phi as their main processor.
In networking, the transition to 10 Gbit/s Ethernet as a clustering interconnect continues with 204 of the 228 Ethernet-based systems using 10GE chips. Rival InfiniBand saw its share shrink to 163 systems from 178 on the previous list. Intel’s Omni-Path interconnect appeared in 35 systems, down from 38.
