Two papers authored by researchers from Pacific Northwest National Laboratory (PNNL) were recently featured in the main program of the 2023 International Symposium on Computer Architecture (ISCA). The symposium was held on June 17 – 21 in Orlando, Florida.
The first paper, “Spy in the GPU-box: Covert and Side Channel Attacks on Multi-GPU Systems” by PNNL authors Sankha Baran Dutta, Andrés Marquez, and Kevin Barker, exposes vulnerabilities in microachitectural gaps in graphics processing unit-based systems.
The second, “Q-BEEP: Quantum Bayesian Error Mitigation Employing Poisson Modeling over the Hamming Spectrum”, outlines a new approach to reducing errors in quantum computing. PNNL researchers Samuel Stein, James Ang, Ang Li, and Joint Appointee Nathan Wiebe co-authored this paper.
These papers were featured in the security and quantum sessions of the ISCA, respectively.
PNNL researchers investigate challenges in computer architecture under several different projects. Barker manages the Center for Advanced Technology Evaluation (CENATE), which helps meet researcher needs by assessing the applicability of new computing architecture to pressing scientific problems. Marquez leads the Advanced Memory to Support Artificial Intelligence for Science (AMAIS) project to develop a memory platform for new devices. Both projects are supported by the Department of Energy (DOE), Office of Science (SC), Advanced Scientific Computing Research program.
The Data-Model Convergence initiative led by Ang uses a multidisciplinary software and hardware co-design methodology to create the next generation of scientific computing capability. The co-design Center for Artificial Intelligence-focused Architectures and Algorithms (ARIAA) focuses on developing technologies for the application of artificial intelligence. ARIAA Director Roberto Gioiosa also participated in ISCA by serving on the program committee for the related 7th Workshop on Cognitive Architectures.
PNNL scientists also contribute their expertise to several DOE, SC, National Quantum Information Science Research Centers: the Co-design Center for Quantum Advantage (C2QA) led by Brookhaven National Laboratory, Q-NEXT led by Argonne National Laboratory, and the Quantum Science Center led by Oak Ridge National Laboratory. Both Ang and Li serve on the Cross-cutting Co-design Integration Team at C2QA.
“Spy in the GPU-box” was supported by the Advanced Scientific Computing Research program and the National Science Foundation. “Q-BEEP” was supported by the DOE, SC, National Quantum Information Science Research Centers, Co-design Center for Quantum Advantage (C2QA).
