- Merged: No
2. [ROCm] enable hidden unit tests on rocm-2: This pull request aims to enable hidden HLO-related unit tests on ROCm platforms by adding a requires-gpu-rocm tag to the tf_gpu_tags function, renaming it to tf_gpu_tests_tags for generality, and includes a bug fix for a file name correction, although it was not merged.
- URL: pull/27635
- Merged: No
3. Command buffer support nested buffer which has memory allocation/free node.: This pull request addresses the enhancement of command buffer functionality by supporting nested buffers with memory allocation nodes, utilizing move semantics when invoking cuGraphAddChildGraphNode, although it was ultimately not merged into the project.
- URL: pull/27639
- Merged: No
Other Closed Pull Requests
- ROCm Environment Fixes: This topic includes pull requests that address issues related to the ROCm environment. One pull request reverts a previous commit and adds a new ROCm header dependency to fix a broken CI build. Another pull request attempts to fix a failed test on the ROCm platform but was not merged into the main branch.
- Build and Integration Improvements: These pull requests focus on improving build processes and integration. One aims to enable building nvshmem on arm64 machines, contingent on changes from a previous pull request, but it was not merged. Another fixes the dumping process for repeated string fields in debug options to prevent parsing failures.
