В Linux стандартными средствами можно использовать часть оперативной памяти как диск. Для этого требуется указать тип монтирования tmpfs в команде mount
mount -t tmpfs -o size=5G tmpfs /mnt/ram
Теперь путь /mnt/ram можно использовать как обычный каталог. Для чего это может быть нужно?
▫️ Скорость работы с таким каталогом выше чем многие SSD и тем более HDD.
▫️ Если у вас очень быстрый SSD на NVMe M.2 то такой способ особо не прибавит вам скорости, но поможет сохранить ресурс SSD когда требуется обрабатывать очень много мелких файлов и оперативка позволяет выделить нужный объем.
▫️ Оперативка это энергозависимая память, поэтому выключении питания все файлы безвозвратно теряются. Такой "non persistent" каталог гарантирует удаление временных файлов.
Я написал небольшой скрипт для условного теста и сравнения скорости копирования файлов между SSD и RAM.
Вот мои результаты:
Single File Size: 30.0Gb
ssd > ssd: 0:00:12.850 / 2.3Gb/s
sdd > ram: 0:00:06.453 / 4.6Gb/s
ram > ram: 0:00:06.995 / 4.3Gb/s
ram > sdd: 0:00:06.217 / 4.8Gb/s
Dir size: 32.7Gb, File count: 11127
ssd > ssd: 0:00:15.063 / 2.2Gb/s
sdd > ram: 0:00:08.486 / 3.9Gb/s
ram > ram: 0:00:08.032 / 4.1Gb/s
ram > sdd: 0:00:07.026 / 4.7Gb/s
Скрипт для теста ↗️
На моём железе прирост скорости ~2x. Плюс экономия ресурса SSD.
В Windows такой фишки по умолчанию нет, но обязательно найдутся аналогичные решения

⚡️Это гигантский дата-центр Amazon за $11 млрд в Индиане.
Кампус строится под обучение и инференс ИИ и будет потреблять до 2.2 ГВт - примерно как 1 миллион домов.
В состав комплекса войдут собственные электростанции, поэтому нагрузка на местную энергосеть и тарифы для жителей должна быть минимальной.

🚀 AI TRENDS | Anthropic Secures CoreWeave Data Center Capacity Amid Rising AI Demand
Anthropic has agreed to lease data center capacity from CoreWeave to address the growing demand for its AI services, Jin10 reports. CoreWeave announced on Friday that the multi-year agreement will assist Anthropic in building and deploying its Claude AI model. CoreWeave's CEO, Intrator, stated that the deal will involve various Nvidia chip architectures within U.S. data centers. The financial terms of the agreement were not disclosed by either company. Anthropic, similar to OpenAI, has been at the forefront of the AI service surge, sometimes struggling to maintain its products online due to what it describes as 'unprecedented demand.' Earlier this week, Anthropic revealed a collaboration with Broadcom and Google to secure 3.5 gigawatts of energy, noting that one gigawatt of power is sufficient to supply electricity to approximately 750,000 U.S. households simultaneously.

🚀 AI TRENDS | CoreWeave's Junk Bonds Rise Amid Optimism from Tech Deals
CoreWeave's junk bonds experienced a rise in value due to increased market optimism following transactions with several major technology companies. According to Jin10, as of 9:05 AM New York time (21:05 UTC+8), the bonds, which have a coupon rate of 9.75% and a face value of 100 cents, increased to 101.88 cents. During the syndication process, the bond's size was expanded from the initially planned $1.25 billion. Data shows that another convertible bond issued on the same day, which was also increased to $3.5 billion, has yet to begin trading. This financing round is the latest for CoreWeave and occurred just hours after the company announced a new agreement with Meta Platforms to supply AI computing products. On Friday, Anthropic agreed to lease CoreWeave's data center capacity to meet the growing demand for its AI services. CoreWeave's stock rose more than 6% during intraday trading.
