The most powerful supercomputer built

05.11.2012

The US has completed the construction of the world's most powerful supercomputer, which is based on graphics accelerators (GPU) NVidia Tesla. The system is located at the Oak Ridge National Laboratory, Tennessee, which is owned by the Department of Energy. The new supercomputer, named Titan, has a peak performance of 20 petaflops. This value coincides with the power of the largest supercomputer. According to the June ranking of the Top 500 most powerful systems in the world, it is Sequoia, which is located in California and is also owned by the US Department of Energy.

According to NVidia, the Titan computer is equipped with 18688 NVidia Tesla K20 modules based on the most modern NVidia Kepler architecture. They provide 90% of system performance. Each module contains one 16-core AMD Opteron processor. The new supercomputer is designed for open scientific research. It is available to all researchers at universities, government laboratories, and other institutions where Titan resources can be used to simulate physical and biological phenomena and produce results through live experimentation.

NVidia CTO Steve Scott (Steve Scott) listed the main areas of application of Titan: materials research at the atomic level, climate change research, biofuel research, nuclear energy, fuel combustion processes and astrophysics. In addition, Titan plays a key role in the transition to the exascale level of computing, as the next stage in the development of the project is the creation of a supercomputer with a capacity of 1 thousand petaflops, added the press service of NVidia.

Thanks to the low power consumption and low price of the Tesla K20 modules, the Titan computer is 10 times faster and 5 times more economical than its predecessor, the Jaguar system (2,3 petaflops of power for the same size). If Oak Ridge National Laboratory upgraded Jaguar by adding more traditional processors, the system would be 4 times larger and consume more than 30 MW.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Medicines from the tap 01.09.2008

A study of tap water in 24 US cities showed that it contained traces of painkillers, stimulants, antidepressants, sedatives, antibiotics - 56 drugs in total. They enter the water supply from the sewer, having passed through the body of the sick, or with pills and potions, the need for which has disappeared and they have been flushed down the toilet.

The doses are only a few parts per billion or trillion parts of water. However, the effects of taking the smallest doses of unprescribed medications have been completely unexplored for decades.
