Expression Isolation of Compiler-Induced Numerical Inconsistencies in Heterogeneous Code
Published in International Conference on High Performance Computing, 2023
Ciel is a tool that pinpoints compiler-induced numerical inconsistencies in heterogeneous programs using a precision-enhancement and recursive bisection strategy, achieving high accuracy and efficiency over prior methods across synthetic, benchmark, and real-world scientific applications.

MUPPET: Optimizing Performance in OpenMP via Mutation Testing
Published in The 15th International Workshop on Programming Models and Applications for Multicores and Manycores, 2024
MUPPET is a source-level mutation testing framework for OpenMP programs that discovers and evaluates code modifications to improve performance, enabling developers to identify optimization opportunities overlooked by compiler IR-based techniques and achieving speedups in 70% of tested benchmarks and proxy applications.

Input Range Generation for Compiler-Induced Numerical Inconsistencies
Published in The 38th ACM International Conference on Supercomputing, 2024
CIGEN is a tool that detects input ranges likely to trigger compiler-induced numerical inconsistencies by combining input partitioning, coverage-guided sampling, clustering, and optimization, achieving a 53.4% improvement over prior methods on GNU Scientific Library functions and enabling deeper analysis of inconsistency causes.

An Automated OpenMP Mutation Testing Framework for Performance Optimization
Published in Journal of Parallel Computing, 2024
MUPPET is a source-level mutation testing framework for OpenMP programs that identifies and evaluates code changes to uncover performance defects and optimization opportunities overlooked by compiler IR-based methods, using multiple search algorithms to find mutations that yield speedups in 75.9% of tested benchmarks and proxy applications while preserving correctness.

FloatGuard: Efficient Whole-Program Detection of Floating-Point Exceptions in AMD GPUs
Published in The 34th ACM International Symposium on High-Performance Parallel and Distributed Computing, 2025
FloatGuard is the first framework for efficiently detecting floating-point exceptions in HIP programs on AMD GPUs, combining hardware register access, hybrid instrumentation, and debugger-guided execution to overcome AMD’s trapping limitations, detect exceptions with low overhead, and reveal key differences from NVIDIA GPU behaviors.

Tools to Diagnose and Repair Floating-Point Errors in Heterogeneous Computing Hardware and Software
Published:
More information here
As assistant, I presented the tool Ciel, which pinpoints where compilers silently over-optimize and cause non-reproducibility. We demonstrated our tools on simple examples with seeded bugs. Attendees may optionally install and run our tools. The tutorial also allocates question/answer time to address real situations faced by the attendees.
