SUMMARY:Profiling the Impact of Hyper-Threading on Pagosa Hydrocodes
DESCRIPTION:Blake Milstead (University of Tennessee, Knoxville)\n\nPagosa 
 is a hydrodynamics computer code designed for massively parallel environme
 nts, operating within an Eulerian framework using a fixed Cartesian mesh. 
 This project investigates the performance of Pagosa on Sapphire Rapids nod
 es, which feature many-core architectures and high bandwidth memory. By co
 nducting strong and weak scaling studies, we aim to evaluate the impact of
  hyper-threading and propose modifications to Pagosa’s MPI environment, in
 cluding a hybrid MPI and OpenMP parallel decomposition. The anticipated ou
 tcomes will inform strategies for optimizing Pagosa, ensuring it remains c
 apable of tackling complex computational problems efficiently.\n\nRegistra
