This dissertation aims to address the correctness and reproducibility challenges in Graphical Process Unit (GPU)-accelerated applications, which are becoming increasingly prevalent in High-Performance Computing (HPC) and Artificial Intelligence (AI) domains. The growing use of GPUs as accelerators has introduced new challenges in ensuring the accuracy and consistency of numerical computations. One major source of these challenges is the inherent nature of floating-point arithmetic, which is heavily used in GPU-accelerated applications. Floating-point arithmetic is prone to numerical errors that can accumulate and lead to incorrect or inconsistent results. The massive parallelism of GPUs and the use of reduced precision formats exacerbate these challenges, making it difficult to detect and correct floating-point errors. Moreover, the lack of standardization in reduced precision formats across different GPU vendors poses significant challenges in maintaining the reliability and portability of GPU programs.This dissertation focuses on developing techniques and tools for floating-point error detection and tuning in GPU programs. The proposed work includes a tool called GPU-Floating Point Exception (GPU-FPX) that detects floating-point exceptions on Nvidia GPUs, and a test suite called Feature Targeted Tests for Numerical-libraries (FTTN) that identifies the numerical behaviors of Advanced Micro Devices (AMD) and Nvidia GPUs. These methodologies and tools aim to provide developers with practical solutions for understanding and addressing the challenges of numerical accuracy in GPU programming, ultimately enabling the creation of more robust and reliable GPU-accelerated applications across a wide range of domains, from scientific simulations to deep learning.
