Exploiting Task-Based Parallelism for the Red-Black Gauss-Seidel Method on 2D Grids
Shiting Long, Gustavo Ramirez-Hidalgo, Andreas Frommer +1
Gauss-Seidel is a well-established iterative method for the solution of linear systems, and multicoloring has been widely used to increase parallelism in iterative solution techniq…
Characterizing the Impact of Congestion in Modern HPC Interconnects
Lorenzo Piarulli, Marco Faltelli, Dirk Pleiter +7
High-performance computing (HPC) systems increasingly support both scalable AI training and large-scale simulation workloads. Both typically rely heavily on collective communicatio…
Performance-Portable Optimization and Analysis of Multiple Right-Hand Sides in a Lattice QCD Solver
Shiting Long, Gustavo Ramirez-Hidalgo, Stepan Nassyr +3
Managing the high computational cost of iterative solvers for sparse linear systems is a known challenge in scientific computing. Moreover, scientific applications often face memor…
