TOP500 Meanderings: Russia’s New Supercomputing Rankings Reflect Sluggish Growth in HPC There


This week Russia posted its list of the 50 most powerful supercomputing systems installed in the country. From the looks of things, not much is happening in HPC space there. System turnover across the Top50 during the last six months was minimal and aggregate performance barely budged.

Only three Russian supercomputers were new to the April list, although six of the existing systems were upgraded or were tweaked to deliver better results for the Linpack benchmark – the standard measurement for HPC performance. As far as aggregate Linpack performance goes, the list increased only 3.7 percent: from 8.1 petaflops to 8.4 petaflops. That’s quite a bit less than the international TOP500 list, which increased its aggregate Linpack performance by 18.5 percent over the previous six months.

The slow increase in performance was a direct result of the slow turnover, especially at the top of the list. There were no new big systems that were deployed over the last six months, although some of them turned in better Linpack scores for the April rankings.

The top Russian supercomputer continues to be the “Lomonosov-2” system installed at Moscow State University. Built by T-Platforms, Lomonosov-2 is an Intel Xeon/FDR InfiniBand cluster, accelerated with NVIDIA K40M GPUs. It’s been the number one system for the last five editions of the list, during which time it was upgraded twice. In its current form, it delivers 2.1 petaflops running Linpack. It represents the only petascale supercomputer in Russia.

The number two supercomputer is Moscow State University’s original…
