48-core Cavium ThunderX processors

13.12.2014

Cavium announced the availability of ThunderX processors for single and dual socket systems. ThunderX CN88xx series processors are built on the ARMv8 architecture and, according to the manufacturer, are designed for next-generation cloud infrastructure and data centers.

The processors, which the developer himself refers to the fifth generation of his multi-core processors, use cores of his own design. The processors are designed to be produced using 28-nanometer technology. They are fully compliant with the ARMv8 and ARM Server Base System Architecture (SBSA) specifications.

Recall, speaking recently about the possibility of using "alternative processors" in supercomputers, Cray mentioned a collaboration with Cavium, which is developing computing clusters on 48-core Cavium ThunderX processors, optimized for load.

The manufacturer refers to the advantages of ThunderX for the first time scalability from 24 to 48 cores, while maintaining compatibility at the level of location and pin assignment. In addition, ThunderX is the first ARM-based single-chip systems with full cache coherence for two processor sockets connected by a Cavium Coherent Processor Interconnect (CCPI) connection.

SoC configuration includes up to four 72-bit memory controllers with support for DDR3 and DDR4 memory operating at an effective frequency of up to 2400 MHz. The maximum amount of memory supported by a dual processor system is 1 TB.

New SoCs are characterized by the presence of numerous hardware accelerators that are in demand in the tasks of information protection, data storage, networking and virtualization. Full system-level virtualization is provided by Cavium virtSoC technology. Embedded I/O has throughput in the hundreds of Gbps. Ethernet support allows you to connect thousands of ThunderX-based nodes.

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, ... >>

New wireless data record 28.05.2016

A team of researchers from the University of Stuttgart and the Fraunhofer Institute for Integrated Circuits set a record by transmitting data over a distance of 37 km at a speed of 6 Gbps. This is 10 times faster than modern equipment.

The data was transmitted between two antennas, the first of which was in Cologne, the second - in Wachtberg, located at a specified distance from Cologne. In Cologne, the antenna was installed on a 45-storey building, and in the second city - on the dome of the observatory.

This record speed was achieved using highly efficient transmitters and receivers in the 71-76 GHz band, intended for terrestrial and satellite broadcasting. The problem of signal attenuation during the passage of such a large distance was solved by using monolithically integrated millimeter wave circuits.

These circuits are based on gallium nitride transistors developed by the Fraunhofer Institute for Integrated Circuits. Thanks to them, the signal was amplified to a relatively high power of 1 watt. In addition, a highly directional parabolic antenna was used to transmit the signal.

Finally, the receiving antenna was connected to a low self-interference amplifier based on high-performance transistors with indium-gallium-arsenic semiconductor layers for high electron mobility. Such an amplifier made it possible to receive a weakened signal that had traveled such a long distance.
