PROFILE

Worked on the ROCm/aiter repository to expand GPU hardware support and optimize kernel performance using CUDA, HIP, and Python. Delivered three features over two months, including adding gfx12 architecture support with backward-compatible enhancements and implementing GemmaRMSNorm and FP8 KV cache support for the fused QK-norm MRoPE kernel on gfx1201. Developed channel-last memory layout support for the causal_conv1d_fwd_split_qkv HIP kernel, introducing dynamic dispatch based on input strides. Focused on performance optimization and cross-architecture compatibility, while maintaining comprehensive test coverage with PyTest and PyTorch to ensure reliability and guard against regressions. No major bugs were reported.
