AI clusters

Homa, a transport protocol designed for data centers, is being presented as a replacement for TCP in AI training clusters. The argument is that TCP's limitations on latency and congestion control make it poorly suited to the traffic patterns of large-scale machine learning workloads, and that purpose-built protocols can deliver better performance for GPU clusters.

A week of releases across the Linux ecosystem: OpenMandriva ROME 26.09 and Nitrux 7.0 shipped, Ubuntu 26.10 entered beta, and updated versions of Firefox 157, Wine 11.19 and Git 2.56 landed. In project news, the COSMIC desktop has stopped accepting AI-generated pull requests, a decision drawing attention among developers. The roundup bundles the main open-source headlines from the past week.
