March 2025: Delivered foundational rocisa integration and improved modular usage of TensileCreateLibrary in StreamHPC/rocm-libraries. Implemented Meyer's singleton for post-C++11 compatibility, refreshed CMake and copyright notices, and launched comprehensive rocisa documentation scaffolding and README updates to support maintainability and onboarding. Stabilized changes by reverting rocisa-related issues (#1821) to ensure a reliable baseline and upstream alignment. Impact: faster feature adoption, clearer release readiness, and a stronger, more maintainable codebase.

February 2025 performance and core-compiler month for StreamHPC/rocm-libraries. Delivered targeted features to accelerate auto-tuning and expand hardware support, while hardening the build and serialization pathways to reduce maintenance risk. The work improves NN workloads, tuning workflows, and profiling capabilities, directly contributing to better ROI for ROCm deployments.

January 2025 highlights for StreamHPC/rocm-libraries: Delivered features and fixes across benchmarking, tuning, and developer workflow that collectively increase performance, broaden data coverage, and reduce maintenance overhead. Key outcomes include: (1) Expanded benchmarking data type support by mapping the B data type to bf16_r in find_exact.py, broadening coverage for performance analysis. (2) BBS kernel tuning and NN/NT/TN equality tuning for gfx942_80cu to boost throughput and accuracy on this hardware. (3) TensileLite build workflow documentation with a README and Makefile-based process to accelerate iterative development and tuning. (4) GlobalWriteBatch optimization for alpha multiplications using v_pk_mul_f32 across long and short stores, including conditional fp32 conversions when the write width > 1. (5) 64-bit move instruction optimization (VMovB64/SMovB64) to improve data movement system-wide. (6) TensileLite client 32-bit index overflow fix by using unsigned size_t for initial calculations and 64-bit accumulation where needed. (7) GlobalWriteBatch gwvw > 1 route cleanup to remove redundant logic and guard initializations. These changes span several commits and PRs, contributing to higher performance, resilience, and a faster tuning cycle.

December 2024 (2024-12) monthly summary for StreamHPC/rocm-libraries focused on delivering stable, high-performance GPU kernels and efficient resource management. Key work spanned feature enhancements, occupancy optimizations, and targeted bug fixes that collectively improve reliability, throughput, and applicability across ROCm platforms.

November 2024 performance summary for StreamHPC/rocm-libraries: Delivered two core features to improve observability and resource discipline across Tensile and hipBLASLt. Benchmark Logging Improvements add solutionIndex to GEMM benchmarks, enabling precise debugging and cross-implementation performance analysis. Kernel Resource Management and Occupancy Improvements refactor register allocation and VGPR/SGPR occupancy calculations, with fixes for non-unified memory configurations and gfx12 occupancy edge cases to improve reliability and performance. The changes were implemented through a broad set of commits (including fixes for accvgpr offsets, next_free_vgpr handling, SGPR occupancy, setOccupancyLimit, and gfx12 hotfixes) and culminated in more stable kernels and better performance tuning.
