Russian supercomputers water cooling will be in 2013

"T-Platforms’ started to develop supercomputing blade platform to fully water-cooler. The company estimates that the works will take two years and $ 10 million
As told CNews chief systems architect Russian manufacturer of supercomputers "T-Platforms" Andrew Slepuhin the end of 2012, the company plans to develop a prototype, and in 2013 — to bring to market a computing platform to create a supercomputer capacity from 1 Pflops to be completely cool water.

"T-Platforms" intend to create a system that can be completed with only a CPU or a hybrid solution CPU + GPU. In the first case, the peak performance of rack should reach 85-105 teraflops, in the second — up to 500 teraflops.

Now there is a concept design of architecture, spoken in a "T-Platforms." Slepuhin notes that developers have to solve many technical problems: for example, to develop a strong power system, water-cooled, determine the extent of the use of optical connections to ensure maximum safety of water cooling.

In developing each of the above technical solutions, it is necessary to take into account the cost of implementation, so that the price of ready solutions for all technical advantages remain competitive, the company says.

Blade servers, which the company now produces are supplied in chassis height 5U and 7U. In contrast, the platform only on water cooling will be a rackmount solution, ie, — Blades are inserted directly into the cabinet. The company said that for this system will be designed in its own stand, as existing standard solutions do not meet the requirements for infrastructure and internal layout of the cooling system.

It should be noted that the "T-Platforms" already equipped with its current blade platform cooled. In particular, it has now developed a solution with mixed cooling, in which the computing nodes are cooled by water, and the control unit, power supplies and switches — air.

Water cooling this solution is implemented as follows: in the chassis are arranged with internal cooling channels board for water circulation pipe connected to the water. To them through a single input is a liquid, and the compute nodes are inserted into the chassis, tightly adhering to the cooling circuit boards. To divert water as there is only one way out. This water pipe connectors for the entry and exit fluid located outside the chassis. According to the authors, no internal releasable pipe connection significantly reduces the risk of water leakage and improves the reliability of the decision.

"This is an interim solution, which we are working on a number of technologies, they will be applied in dealing with the next generation — explains the director of marketing for" T-Platforms "Alex lumps. — Subsequently, however, will have to seriously alter a water cooling system to cool the water not only compute nodes, but all the other components of the fuel. "

Cooling in addressing the next generation, according to Komkova, to be implemented on the same principle: the water supply to the joint between the boards is cooling and transport it from the whole entire rack, not on each compute node.

Computational installation on a water-cooled already established in Russia. For example, a system with a peak performance of 117.6 teraflops, set in the South Ural State University. It uses the platform "SKIF-Aurora", developed in alliance with Italy’s Eurotech, RSC SKIF PSI RAS and with the support of Intel. Its development began in 2008, and by the beginning of cooperation with Russian partners have already been created hardvernye basic components such as motherboard, cooling water system, the chassis. In that decision, the water is piped to each individual computing node in the chassis.

Director of the IRS them. AK Ailamazyan RAS Sergei Abramov told CNews, he did not consider the presence of compounds of water tubes inside the chassis weakness "SKIF-Aurora", over which need further work, as the "platform has all the necessary certification and meets the security requirements." And in order to evaluate the cooling system "T-Platforms", first you need to see it in the form of running, he said.

It is estimated that the Director of Marketing "T-Platforms’, the development of the blade system for a new generation of water-cooling would require an investment of $ 10 million Part of the funds for these purposes, the company expects to use the money earned from, and some — to draw from the VEB and placement of bonds MICEX.

Recall that the company recently decided to issue bonds in the total nominal value of 100 million rubles., And in October 2010 the decision to enter the capital "T-Platforms" took Vnesheconombank. The deal with the bank, according to the parties, is still being prepared.

Completely abandon the blade with air cooling in the company do not plan to. According to the company, and at least two generations of platforms will be cooled by air. These systems will be used to build supercomputers small and medium power.

Supercomputing platform entirely on water cooling are already creating the world’s largest vendors. For example, Cray and IBM. Personal Supercomputers on the mixed air-water cooling produces the Federal Nuclear Center in Sarov.
