Chebyshev

Also known as SKIF MSU; SKIF MSU Chebyshev; Chebyshev T-Platforms T60

Operated by Lomonosov Moscow State University at MSU Research Computing Center .

Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Measured performance

Rmax: 47.17 TFlop/s
Rpeak: 60.00 TFlop/s
Rmax ÷ Rpeak: 78.6%
Cores: 5,000
Power: 265 kW
Per watt: 0.2 GF/W

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.

What this machine is made of

One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read

Moscow State University's SKIF MSU 'Chebyshev' cluster, built by T-Platforms. The parallel.ru system page describes 625 compute nodes, 1,250 quad-core Xeon processors (5,000 cores) at 3.0 GHz, InfiniBand DDR with Mellanox ConnectX, 5.5 TB of RAM, 60 TFlop/s peak and 47.04 TFlop/s Linpack. TOP500 lists 5,000 cores of Xeon E5450 3 GHz (the MSU page names the E5472) on InfiniBand DDR running CentOS at 47.17 TFlop/s Rmax, 60.00 TFlop/s Rpeak and 265 kW, 37th in June 2008, then 55th, 82nd, 103rd, 121st, 181st and 353rd in June 2011, its last appearance. The Lomonosov system that followed it at MSU is a separate entry in this dataset.

Source check

We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.

Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.

Cited source	Result	Found on the page
parallel.ru	does not name this system	Mellanox InfiniBand DDR
top500.org	does not name this system	Mellanox InfiniBand DDR, CentOS
