Anerudhan Gopal
Worked on the flashinfer-ai/flashinfer repository, delivering core deep learning and GPU computing features focused on performance and reliability. Over five months, contributed native cuDNN integration for sequence decoding and prefill operations, optimized graph caching for GEMM dequantize graphs, and enabled FP8 support for quantized attention with broader hardware compatibility. Used C++, Python, and CUDA to refactor kernel loading, streamline backend logic, and implement robust unit testing. Enhanced test reliability and documentation, ensuring stable releases and improved throughput. The work addressed both backend and API integration challenges, resulting in lower latency, higher scalability, and dependable deployment across diverse CUDA environments.

Dec 1, 2025December 2025 monthly summary: Delivered FP8 support in the cuDNN backend with broader version compatibility, enabling efficient attention on quantized tensors and expanding deployment across cuDNN 9.17.1+. Implemented initial FP8 Q/KV cache support and added a cudnn-native backend option for SDPA FP8. Expanded FP8 capability with per-head/per-device calibration tensors, dummy-scale handling, and an optional output data type. Lowered the minimum cuDNN version requirement from 9.18.0 to 9.17.1 to enable FP8 on older cuDNN versions. Added comprehensive FP8 validation tests with passing results and updated benchmarks/docs to reflect FP8 backend behavior. All tests pass across CI.
