Optimizations have been prepared for the Linux kernel to improve the performance of I/O schedulers

Submitted by

Jens Axboe, creator of io_uring and the I/O schedulers CFQ, Deadline and Noop, has continued his experiments with I/O optimization in the Linux kernel. This time, his attention came to the BFQ and mq-deadline I/O schedulers, which turned out to be a bottleneck at least in the case of high-speed NVMe drives. As the study of the situation showed, one of the key reasons for suboptimal performance of subsystems […]

TSMC has created an improved magnetoresistive memory - it consumes 100 times less energy

Submitted by

TSMC, together with scientists from the Taiwan Industrial Technology Research Institute (ITRI), presented a jointly developed SOT-MRAM memory. The new storage device is designed for in-memory computing and for use as a high-level cache. The new memory is faster than DRAM and retains data even after power is turned off, and it is designed to replace STT-MRAM memory, consuming 100 times less […]

Microsoft and Caterpillar powered the data center for 48 hours from a 1,5-MW Ballard hydrogen battery

Submitted by

Caterpillar Electric Power and Microsoft announced a successful experiment in which exclusively hydrogen fuel cells were used to power a data center. According to the Caterpillar press service, they provided electricity to the Microsoft data center for 48 hours. The partners invited fuel cell developer Ballard Power Systems to collaborate. Used a large-format hydrogen cell to power Microsoft's Cheyenne data center […]

New article: ID-Cooling SL360: mini-space on your processor

Submitted by

An interesting example of expanding the functionality of a maintenance-free life support system is the LCD display on the pump, which displays monitoring data and other useful information. This material contains traditional tests of the cooling efficiency and noise level of a bright new product on a very hot processor. Source: 3dnews.ru

FreeBSD developers discuss using the Rust language in the base system

Submitted by

Alan Somers, developer of the new FUSE driver implementation for FreeBSD and author of the Rust wrappers for some of the FreeBSD libraries, began discussing the process of incorporating Rust code into the base system. During the discussion between the project committers, the cost and benefits of implementation were determined. The cost of enabling Rust support is doubling the build time, but the benefit is that it simplifies the development of some […]

8.2% of the top NPM downloads are for legacy packages

Submitted by

Researchers from Aqua Security published the results of an analysis of statistics on the 50 thousand most downloaded packages in the NPM repository. 7500 (15%) of the most downloaded packages were associated with outdated packages and defunct projects. To simplify the identification of outdated packages among the dependencies used in your project, the Dependency-Deprecated-Checker utility, published under the MIT license, is proposed. In 4100 (8.2%) examined […]

Chinese underwater data centers HiCloud have proven their functionality

Submitted by

The first commercial underwater data center in China, which is being created by HiCloud Data Center Technology (a division of Highlander), has confirmed its functionality. The system, as reported by Datacenter Dynamics with reference to Chinese media, has been operating stably since it was put into operation at the end of last year. Moreover, HiCloud reported that it had received orders from China Telecom and SenseTime to create the same […]
