The 61st edition of the List has been released at ISC23.
Leonardo, which debuted on the Top500 List six months ago, retains its fourth place among the world’s most powerful supercomputers, and second in Europe. But compared to last November’s rank, the Cineca-hosted EuroHPC JU system increased its HPL performance from 174 to 238.7 PFlops, or 238.7 million billion operations per second. The jump added an additional 36.6 percent compute mass, bringing Leonardo’s Booster module to 95 percent of its full configuration.
Twice a year the Top500 compiles an updated list of the most powerful supercomputers globally, ranking them according to a system based on measuring performance with Linpack Benchmark: basically it consists of stressing the machine by making it solve dense systems of linear equations, scaling the problems so as to achieve the highest possible speed.
Anders Dam Jensen, executive director of EuroHPC JU, commented:
LUMI and Leonardo continue to impress on both a European and global scale. I am pleased to see that our pre-exascale systems continue to rank in the TOP500 and that all EuroHPC supercomputers are ranked among the most powerful supercomputers in the world. These rankings are proof of our ability to realize our goal of placing Europe in a leadership position in HPC.”
The next steps for Leonardo now are to put it into production and, at the hardware level, to install the Data Centric / General purpose module, which will further expand the machine’s capabilities.
