January 2026 performance summary: Delivered a major ROCm stack upgrade across getsolus/packages with amd-blis v5.1 and rocwmma v7.0.1 initializations, plus ROCm 7.0.2 library/tooling updates (miopen, hipcub, hiprand, pytorch, torchvision, torchaudio, torchtext) and sccache/jujutsu. Updated core rendering stack and dependencies (Embree 4.4.0, rkcommon 1.14.0, openvkl 2.0.1, openimagedenoise 2.3.0 with HIP temporarily disabled, ospray 3.2.0, opencolorio 2.5.1, openimageio 3.1.9.0, blender 5.0.1) to improve stability and performance. Migrated build system from Bazel to Bazelisk, enabling streamlined tooling; implemented image-packaging improvements (zstd/libwebp CMake configs, -devel rundeps) and several stability fixes (hipblaslt rocm-openmp-devel removal, libhsakmt propagation, hsakmt removal, minizip-ng zlib-ng fix). In pytorch/pytorch, removed obsolete compile-time test to prevent build failures and improve code clarity. This combination boosts GPU-accelerated workloads, CI efficiency, and long-term maintainability.
