Ishwar Raut enhanced the TensorRT RTX execution provider in the mozilla/onnxruntime repository by consolidating RTX-focused improvements to streamline GPU inference workflows. He removed dependencies on CUDA execution provider DLLs, enabling a more modular RTX path and simplifying deployment. Ishwar introduced RTX-specific allocators and optimized data transfer paths, which improved GPU throughput and reliability. He extended support for ONNX operations to execute directly on TensorRT RTX rather than the CPU, reducing CPU load and increasing inference performance. His work involved C++, CMake, and CUDA, and included aligning DLL naming and versioning for clarity and compatibility, supporting smoother upgrade paths.
May 2025: TensorRT RTX Execution Provider enhancements in mozilla/onnxruntime. Consolidated RTX-focused improvements by removing CUDA EP DLL dependencies to enable a more modular RTX path, added RTX-specific allocators and data transfer paths to boost GPU performance and reliability, and extended ONNX ops to execute on TensorRT RTX instead of CPU. Aligned DLL naming/versioning to RTX for clarity and compatibility. Also addressed a domain check issue to ensure correct RTX operation and updated DLL naming to reflect RTX. Business value includes simplified deployment, higher inference throughput, reduced CPU load, and smoother upgrade paths. Technologies demonstrated include TensorRT RTX EP, ONNX Runtime, C++, DLL management, and performance testing.
