Slicing Is All You Need: Towards A Universal One-Sided Algorithm for Distributed Matrix Multiplication

Many important applications across science, data analytics, and AI workloads depend on distributed matrix multiplication. Prior work has developed a large array of algorithms suitable for different problem sizes and partitionings including 1D, 2D, 1.5D, and 2.5D algorithms. A limitation of current work is that existing algorithms are limited to a subset of partitionings. Multiple algorithm implementations are required to support the full space of possible partitionings. If no algorithm implementation is available for a particular set of partitionings, one or more operands must be redistributed, increasing communication costs. This paper presents a universal one-sided algorithm for distributed matrix multiplication that supports all combinations of partitionings and replication factors. Our algorithm uses slicing (index arithmetic) to compute the sets of overlapping tiles that must be multiplied together. This list of local matrix multiplies can then either be executed directly, or reordered and lowered to an optimized IR to maximize overlap. We implement our algorithm using a high-level C++-based PGAS programming framework that performs direct GPU-to-GPU communication using intra-node interconnects. We evaluate performance for a wide variety of partitionings and replication factors, finding that our work is competitive with PyTorch DTensor, a highly optimized distributed tensor library targeting AI models.

Background Coding Agents: Context Engineering (Part 2) | Spotify Engineering

In , we introduced how Spotify uses a background coding agent to extend Spotify’s Fleet Management system. It can edit code, run builds and tests, and open pull requests (PRs) automatically. Once we had our agents up and running, a new challenge emerged:

체스할때마다 인류애 줄어든다.
하... 지기 시작하니까 기물던지고 일부러 가장 오래걸리는 수순으로 가서 실수유발하는거
진짜 꼭 그래야해? ADHD때문에 흥미 없어지면 못하는데, 게임하기가싫어

This is obscene. The vile Shabana Mahmood has confirmed the new immigration rules will be retrospective.

"Under the incoming rules they will have to wait 20 years after they arrived before they can apply for settlement. It means more than 10,000 refugees who were set to qualify for settlement next year will now have to wait a further 15 years before they can settle"

thetimes.com/article/6f8338d1-

Refugees who were months away from settlement now face 15-year wait

Shabana Mahmood’s asylum reforms will apply retrospectively, it has been confirmed — and it is claimed the bureaucracy will cost up to £1.3bn

I hate the word “impactful” - but I am otherwise very tickled by this honour. ipolitics.ca/2025/11/24/storyt

'Storytime with Paula': Simons named Most Impactful Speaker in the Senate

Alberta Sen. Paula Simons, recipient of iPolitics' Most Impactful Speaker in the Senate award, said the best Senate speeches require "careful research, political passion and strong story-telling – with a leavening of humour."
