Abstract: Efficiently processing long sequences with Transformer models usually requires splitting the computations across accelerators via context parallelism. The dominant approaches in this family of methods, such as Ring Attention or DeepSpeed Ulysses, enable scaling over the context dimension but do not focus on memory efficiency, which limits the sequence lengths they can support. More advanced techniques, such as Fully Pipelined Distributed Transformer or activation offloading, can further extend the possible context length at the cost of training throughput. In this paper, we present UPipe, a simple yet effective context parallelism technique that performs fine-grained chunking at the attention head level. This technique significantly reduces the activation memory usage of self-attention, breaking the activation memory barrier and unlocking much longer context lengths. Our approach reduces intermediate tensor memory usage in the attention layer by as much as 87.5$\%$ for 32B Transformers, while matching previous context parallelism techniques in terms of training speed. UPipe can support the context length of 5M tokens when training Llama3-8B on a single 8$\times$H100 node, improving upon prior methods by over 25$\%$.

sp_high_school_new: High school dynamic contacts (2011-2012)
These datasets contain the temporal network of contacts between students in a high school in Marseilles, France. The first dataset gives the contacts of the students of three classes during 4 days in Dec. 2011, and the second corresponds to the contacts of the students of 5 classes during 7 days (from a Monday to the Tuesday of the following week) in Nov. 2012.
This network has 126 nodes and 28561 edges.

Kraken launches what it claims are the first regulated perpetual futures contracts based on tokenized stocks, available to non-US users and trading 24/7 (Krisztian Sandor/CoinDesk)

Kraken brings crypto-style, 24/7 perpetuals trading for tokenized U.S. stocks
The crypto exchange is bringing U.S. stocks closer to the crypto world, letting users trade derivatives of tokenized stocks around-the-clock and with 20x leverage.

…sometimes there’s •not• a clear standard way. Sometimes you need flexibility. For example, a lot of what makes UI programming hard is layout: you have to make your own very specific application look good on a variety of devices and screens, which means coming up with an •algorithm• for adjusting your design for all those different contexts.
That’s an intrinsically hard problem that requires design chops and nuance and contextual knowledge. Attempts to abstract the decisions out of that problem have been stubbornly unsuccessful. (How many layout engines are out there now?)
