Jan 1, 2026

Month: 2026-01 — Focused on building extensibility for hipDNN within ROCm/TheRock. Delivered FlatBuffer Build Integration and hipDNN Artifacts for Graph Nodes and Engine Plugins, enabling users to define and modify graph nodes and plugins via flatbuffers. This included integrating flatc into the build system (CMake) and publishing artifacts that include the necessary flatbuffers tooling. This work improves forward compatibility of serialized graphs, accelerates user-driven extension of frontend nodes and engine plugins, and enhances standalone hipDNN build workflows. Major bugs fixed this month: none reported. The changes are documented in commit 0c350044654a490aabd9846b3c273a0ae6dd0443, with test results showing flatc binary and cmake targets are available and standalone hipDNN builds are validated (see issue #3516).

Dec 1, 2025

Concise monthly summary for 2025-12 focusing on ROCm/TheRock. The work centered on build-system modernization to decouple hipDNN from MIOpen and enable independent builds, while laying the groundwork for TheRock plugin_sdk migration. A new stub package was introduced to support TheRock builds and future migration from the existing sdk. Packaging and test readiness updates were completed to facilitate CI/CD validation and artifact installation.
