PROFILE
Shruthi Gorantala
Shruthi Gopalakrishna developed advanced compiler tooling and cloud deployment workflows in the google/heir repository, focusing on secure computation and scalable infrastructure. She engineered features such as batched LUT3 operation conversion, boolean vectorization, and polynomial evaluation passes, leveraging C++, Python, and MLIR to optimize intermediate representation and pipeline performance. Her work included robust build system enhancements using Bazel, cloud provisioning automation for Google Cloud TPUs, and disciplined deprecation of legacy GCP scripts to streamline maintenance. By addressing memory model correctness, data packing reliability, and documentation clarity, Shruthi demonstrated depth in low-level optimization, DevOps, and type-driven code generation across complex workflows.

Oct 1, 2025October 2025 monthly summary for google/heir. Focused on delivering enhanced polynomial handling in the heir-polynomial-to-llvm conversion pipeline. Key work included introducing a new pass createLowerPolynomialEval in the polynomialToLLVMPipelineBuilder to enable evaluation of polynomial expressions during LLVM IR generation, along with a dedicated test lower_poly_eval to verify correctness within the conversion pipeline. The feature is exposed via a configurable flag (--lower-polynomial-eval) to control its activation in the pipeline. Committed work includes 98d3d340ede863d3d1dd92548d304b639436abbe with the message: Add a test for lower poly eval. Also add --lower-polynomial-eval pass to heir-polynomial-to-llvm pipeline.

Aug 1, 2025August 2025 (Month: 2025-08) -- google/heir: Key features delivered: - Removed GCP TPU provisioning scripts and deprecated GCP integration to decouple the repository from direct Google Cloud provisioning. - Deleted documentation and Python scripts for provisioning, running, and destroying TPU resources on GCP, reducing cloud-provider surface area and maintenance overhead. Major bugs fixed: - No major bugs reported for google/heir in this period based on available data; effort focused on deprecation and cleanup rather than bug fixes. Overall impact and accomplishments: - Simplified maintenance and improved security/compliance posture by decoupling from GCP, aligning with broader platform strategy. - Reduced operational overhead and risk associated with TPU provisioning tooling, enabling easier migration to alternative infrastructures in the future. - Demonstrated disciplined deprecation strategy and clean-up of cloud-specific tooling, paving the way for more modular resource management. Technologies/skills demonstrated: - Python scripting cleanup and documentation removal, with careful version control discipline. - Cross-repo tooling awareness, evidenced by related activity in google/fully-homomorphic-encryption (commit bfcb519aca28f186d3d8739f3f1ffc4d2865edcc). - Focus on business value through simplification, governance, and maintainability of cloud integrations.

Dec 1, 2024December 2024: Delivered a Boolean Vectorizer in the TOSA-to-Jaxite pipeline for google/heir, introducing a boolean vectorization pass and a new parallelism option. The vectorizer is activated when parallelism > 0 and is integrated into the pipeline flow, with a dedicated test example for pmap_add_one_lut3 to validate functionality. This work enhances data-parallel performance in the translation path and expands TOSA->Jaxite capabilities. Commit 733c915347e16707c67617cd31bb12474788c4d9 documents the change and serves as the integration point for this feature.
