May 2026: Stabilized CI and release readiness for ROCm/rocm-jax by reverting the ROCm base image upgrade from 7.2.2 back to 7.2.0, restoring build/test workflows and preventing pipeline downtime. This ensured continued development and validated compatibility against the 7.2.0 baseline, enabling timely feature work and releases.

April 2026 monthly summary focused on ROCm testing stability, CI infrastructure, and ROCm-related kernel/module reliability across JAX (jax-ml/jax) and XLA (openxla/xla).

March 2026: Stabilized ROCm paths in jax and XLA by delivering test resilience for GPU workloads and memory hygiene for profiling. Key outcomes include reducing test flakiness on ROCm GPUs, updating the test suite for consistent results, and adding robust memory cleanup for the ROCm profiler. These improvements enhance reliability, developer velocity, and observability for GPU-accelerated workloads across the codebases.

February 2026 monthly summary for JAX ROCm and related work: Expanded ROCm GPU testing coverage for core numerical routines and utilities, including LOBPCG tests, lax backend SciPy tests, memory-space export tests, and AOT tests on ROCm. This was enabled by a refactor of platform detection to improve cross-platform compatibility and reduce hard-coded assumptions, enabling tests to run on both CUDA and ROCm. Key commits include enabling LOBPCG tests on ROCm (cde00c5e), enabling ROCm SciPy tests (164cd497), enabling ROCm memory-space tests (1817083c), enabling deviceless AOT tests on ROCm (8e7b9fce), and platform-detection improvements (c0a1b80a).

January 2026 focused on unifying GPU support across CUDA and ROCm in both jax-ml/jax and ROCm/jax, delivering cross-platform interop, stabilizing the ROCm testing landscape, and expanding test coverage for ROCm-enabled workflows. The work enhances reliability, broadens device reach, and accelerates validation for ROCm users while strengthening cross-platform memory management and GPU testing practices.
