Dec 1, 2024December 2024 focused on advancing quantization accuracy and reliability in ROCm/triton, strengthening the test framework, and ensuring CI stability and upstream alignment. Delivered int8 FA/KV scaling enhancements with in-test tiling and p_scale handling, added FP32 scaling support, and extended test coverage with no-causal and isolated tests. Performed upstream synchronization with FA-int8 branch and implemented CI/test infrastructure improvements (pre-commit, code cleanup, and enabling full test suite). Major bugs fixed include ref_out order alignment, disabling gradient for testing to save memory, applying code-review fixes, and removing deprecated autotune config. These changes reduce production risk in quantized paths, improve numerical precision, and accelerate development with stronger CI and upstream collaboration.

Nov 1, 2024November 2024: Delivered production-ready INT8 per-channel quantization for the Flash Attention kernel in ROCm/triton, including per-channel scales, a de-quantization path, and dedicated tests. The test suite was streamlined by removing an obsolete INT8 test to improve validation reliability. No major defects reported; focus was on feature delivery with emphasis on performance, memory efficiency, and maintainability. This work strengthens ROCm/triton's low-precision inference capabilities and expands deployment potential for latency-sensitive workloads. Technologies demonstrated include low-level Triton kernel development, per-channel quantization, and robust testing practices.
