Analyzing Resource Utilization in an HPC System: A Case Study of NERSC Perlmutter
Jie Li, George Michelogiannakis, Brandon Cook +2
Resource demands of HPC applications vary significantly. However, it is common for HPC systems to primarily assign resources on a per-node basis to prevent interference from co-loc…
Accelerating quantum many-body configuration interaction with directives
Brandon Cook, Patrick J. Fasano, Pieter Maris +2
Many-Fermion Dynamics-nuclear, or MFDn, is a configuration interaction (CI) code for nuclear structure calculations. It is a platform-independent Fortran 90 code using a hybrid MPI…
Accelerating an Iterative Eigensolver for Nuclear Structure Configuration Interaction Calculations on GPUs using OpenACC
Pieter Maris, Chao Yang, Dossay Oryspayev +1
To accelerate the solution of large eigenvalue problems arising from many-body calculations in nuclear physics on distributed-memory parallel systems equipped with general-purpose…
Efficient Intra-Rack Resource Disaggregation for HPC Using Co-Packaged DWDM Photonics
George Michelogiannakis, Yehia Arafa, Brandon Cook +6
The diversity of workload requirements and increasing hardware heterogeneity in emerging high performance computing (HPC) systems motivate resource disaggregation. Resource disaggr…
ARcode: HPC Application Recognition Through Image-encoded Monitoring Data
Jie Li, Brandon Cook, Yong Chen
Knowing HPC applications of jobs and analyzing their performance behavior play important roles in system management and optimizations. The existing approaches detect and identify H…
Optimizing the Union of Intersections LASSO () and Vector Autoregressive () Algorithms for Improved Statistical Estimation at Scale
Mahesh Balasubramanian, Trevor Ruiz, Brandon Cook +4
The analysis of scientific data of increasing size and complexity requires statistical machine learning methods that are both interpretable and predictive. Union of Intersections (…
