January 2026 (2026-01): Delivered sparse attention (VSA) for the CK_TILE framework in ROCm/composable_kernel, enabling bf16-optimized attention workloads and greater scalability. Refactored kernel implementation into block and kernel components to improve maintainability and future optimization. Strengthened the build and test pipeline with new scripts and tests, including Jenga test support for bf16. Addressed code-quality issues and pre-commit failures to improve CI reliability. This work enhances performance, reduces build friction, and establishes a solid foundation for next-phase optimizations in attention primitives.
