Phoebe Chen
Contributed to the iree-org/iree repository by developing a Conv2D to Img2Col transformation pass within the IREE Compiler, optimizing convolution workloads for both standard and quantized types. This work involved integrating the new pass into the global optimization pipeline through targeted build and configuration updates, enhancing performance for edge and embedded hardware. Additionally, addressed RISC-V timing compatibility in the Benchmark submodule by updating timing measurements to use RDTIME instead of RDCYCLE, ensuring continued benchmark accuracy after Linux kernel changes. Leveraged C++, MLIR, and system programming expertise to deliver robust solutions that maintained CI reliability and cross-environment functionality.

Mar 1, 2026March 2026: Implemented Conv2D to Img2Col Transformation pass in the IREE Compiler to optimize convolution workloads. Added build/config updates to hook the pass into the global optimization pipeline. Extended Img2Col support to quantized types, enabling optimized Conv2D paths for quantized models and sharpening performance for edge/embedded hardware targets. This work is tracked with commit 80d70d6f3e07b2f342f0c44a225fb7d4b579bb65 under the PR/issue: [GlobalOpt] Support Img2Col Transformation for Conv2D Including Quantized Types (#23278).

Jan 1, 2025Monthly summary for 2025-01 for iree-org/iree focusing on RISC-V timing compatibility in the Benchmark submodule. Delivered a fix to use RDTIME instead of RDCYCLE to maintain timing measurement functionality after RDCYCLE became privileged in Linux kernel 6.6, ensuring continued third-party benchmark support and CI stability. The change preserves benchmarking accuracy across environments and mitigates risk of regressions in performance measurements.
