Worked on the bytedance-iaas/sglang repository, focusing on kernel development and GPU computing for machine learning workloads. Delivered a HIP-specific optimization for quantized GEMM weight shuffling, introducing conditional logic to leverage aiter’s shuffle_weight function when appropriate, which improved performance on HIP-enabled platforms. Addressed kernel robustness by explicitly casting program IDs and destination indices to int64 in the pre_reorder_triton_kernel, resolving data-type mismatches and enhancing stability under edge cases. Used Python to implement these changes, applying skills in performance optimization, quantization, and bug fixing. The work demonstrated depth in low-level kernel reliability and targeted improvements for production environments.

Sep 1, 2025September 2025—bytedance-iaas/sglang: Delivered HIP-specific optimization for PTPC GEMM weight shuffling using aiter; introduced conditional usage of aiter's shuffle_weight when SGLANG_USE_AITER is defined and HIP is active; added support path enabling aiter gemm_a8w8_bpreshuffle for PTPC GEMM. No major bugs fixed this period. This work improves performance and resilience of quantized GEMM on HIP-enabled platforms and lays groundwork for broader AITER integration.

Jul 1, 2025July 2025 — bytedance-iaas/sglang: Focused on kernel reliability and data integrity within the sg-lang kernel path. Delivered a targeted bug fix to improve robustness of pre_reorder_triton_kernel by explicitly casting the program ID and the loaded destination index to int64, eliminating default int32-related data-type mismatches. Impact: enhances correctness and stability of kernel execution under edge cases, reducing risk of incorrect results in production workloads and simplifying future maintenance. The change is tracked under commit 5f6756b038ff5de318adbe2d8272ba1e8dc980c5 and addresses the issue referenced as #7814.
