Large Parallelism Post: Part II Megatron-LM: Training Multi-Billion Parameter Language Models Using Model Parallelism
#parallelism
Во второй части нашего ралли по методам параллелизма я подробно разобрал Tensor Parallelism на основе статьи Megatron-LM 🌿
Сама суть методики заключается в параллелизме не просто слоев модели, а ее блоков. В статье разработан пайплайн разделения блоков трансформера (MLP и Attention) с помощью column и row parallelism - так достигается корректность матричных вычислений и нелинейных функций. Особое внимание уделено минимизации коммуникации между GPU - на Forward и Backward приходится всего 4 AllReduce. Также исследован совмещенный пайплайн: Tensor Parallelism + Data Parallel 🪑

Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” These administrators had built substantial positions in these scrips prior to the circulation of recommendations and offloaded their positions subsequent to rise in price of these scrips, making significant profits at the expense of unsuspecting investors, Sebi noted. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea. WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world.
