Feature extraction and visualization algorithm improves functional memory and research outcomes in multiphase flow simulation analysis
By Galen Fader Oak Ridge National Laboratory A joint research team funded by the Department of Energy’s Exascale Computing Project (ECP) has created a novel end-to-end analytics and visualization program for solving domain-specific issues in multiphase flow simulations. The program operates alongside MFIX-Exa, a massively parallel CFD-DEM (computational fluid dynamics–discrete element model) code designed to […]
EXAALT researchers explore speculative task methods to improve scalability
A team working on the ECP’s Exascale Atomistic Capability for Accuracy, Length, and Time (EXAALT) project has developed a task-level speculative method that maximizes parallelism and computational throughput at large scales by predicting whether task-level outputs will be used in subsequent executions.
Novel algorithm delivers flexibility, efficiency for sparse linear system solvers on HPC infrastructures
Researchers funded by the Exascale Computing Project (ECP) have extended the sparse direct solver STRUMPACK to GPU frameworks, providing more flexibility and efficiency for execution of large-scale sparse linear solvers on high-performance computing infrastructures.
