Product-Aware Deterministic Rounding for Quantized Matrix Multiplication
Piyush Sao, Narasinga Miniskar, Pedro Valero-Lara +2
Scalar rounding decisions interact through matrix multiplication. We study deterministic product-aware rounding after scales, clipping bounds, and grids are fixed, with each active…
A Nuclear-Norm Lower Bound for Dithered Scalar Quantization of Matrix Products
Piyush Sao, Narasinga Miniskar, Pedro Valero-Lara +2
We consider the problem of minimizing error in quantized matrix multiplication . Scalar quantization of the factors introduces rounding errors whose scale depends on the maxi…
JLIR: A Julia-Native MLIR-Inspired Intermediate Representation with Automatic JACC Kernel Extraction
Narasinga Rao Miniskar, Seyong Lee, Keita Teranishi +1
The Multi-Level Intermediate Representation (MLIR) has made reusable compiler infrastructure practical for domain-specific computation. However, MLIR's strong compile-time type req…
A Second-Moment Theory for Floating-Point Reduction Trees
Piyush Sao, Narasinga Miniskar, Pedro Valero-Lara +2
Summation error depends on partial-sum order, which standard worst-case bounds omit. To capture this dependence, we derive an exact mean-square error (MSE) recurrence for a binary…
Contraction-Gauge Preconditioning for Quantized Matrix Multiplication
Piyush Sao, Narasinga Miniskar, Pedro Valero-Lara +2
We study low-precision computation of C=AB with both factors quantized. We derive an exact finite-dimensional identity for the expected squared product error under independent, zer…
Classic and Quantum Task-Based Intelligent Runtime for QIRs Running on Multiple QPUs
Narasinga Rao Miniskar, Elaine Wong, Vicente Leyton-Ortega +2
High-performance computing systems are rapidly evolving into heterogeneous platforms that fuse quantum accelerators with traditional classical processing units (CPUs) and graphical…
LightStim: A Framework for QEC Protocol Evaluation and Prototyping with Automated DEM Construction
Xiang Fang, Ming Wang, Yue Wu +6
Fault-tolerant quantum computing increasingly demands rigorous, circuit-level evaluation of diverse quantum error correction (QEC) protocols and efficient prototyping of new ones.…
Q-IRIS: The Evolution of the IRIS Task-Based Runtime to Enable Classical-Quantum Workflows
Narasinga Rao Miniskar, Mohammad Alaul Haque Monil, Elaine Wong +4
Extreme heterogeneity in emerging HPC systems are starting to include quantum accelerators, motivating runtimes that can coordinate between classical and quantum workloads. We pres…
Leveraging AI for Productive and Trustworthy HPC Software: Challenges and Research Directions
Keita Teranishi, Harshitha Menon, William F. Godoy +25
We discuss the challenges and propose research directions for using AI to revolutionize the development of high-performance computing (HPC) software. AI technologies, in particular…
Characterizing GPU Energy Usage in Exascale-Ready Portable Science Applications
William F. Godoy, Oscar Hernandez, Paul R. C. Kent +8
We characterize the GPU energy usage of two widely adopted exascale-ready applications representing two classes of particle and mesh solvers: (i) QMCPACK, a quantum Monte Carlo pac…
Mapping Spiking Neural Networks to Heterogeneous Crossbar Architectures using Integer Linear Programming
Devin Pohl, Aaron Young, Kazi Asifuzzaman +2
Advances in novel hardware devices and architectures allow Spiking Neural Network evaluation using ultra-low power, mixed-signal, memristor crossbar arrays. As individual network s…
