SUMMARY:AP10 - ACM Papers
DESCRIPTION:Paper\n\nPerformance Optimization and Load-Balancing Modeling 
 for Superparametrization by 3D LES\n\nvan den Oord, Chertova, Jansson, Pel
 upessy, Siebesma...\n\nIn order to eliminate climate uncertainty w.r.t clo
 ud and convection parametrizations, superpramaterization (SP) has emerged 
 as one of the possible ways forward. We have implemented (regional) superp
 arametrization of the ECMWF weather model OpenIFS by cloud-resolving, thre
 e-dimensional large-eddy si...\n\n---------------------\nExtreme-Scale Tas
 k-Based Cholesky Factorization Toward Climate and Weather Prediction Appli
 cations\n\nCao, Pei, Akbudak, Mikhalev, Bosilca...\n\nClimate and weather 
 can be predicted statistically via geospatial Maximum Likelihood Estimates
  (MLE), as an alternative to running large ensembles of forward models. Th
 e MLE-based iterative optimization procedure requires factorization of lar
 ge-scale linear systems that consist of a symmetric positi...\n\n---------
 ------------\nProgress Towards Accelerating the Unified Model on Hybrid Mu
 lti-Core Systems\n\nZhang, Xu, Evans, Norman, Morales-Hernandez...\n\nThe 
 cloud microphysics scheme, CASIM, and the radiation scheme, SOCRATES,
  are the two computationally intensive parts within<br />the Met Office&rs
 quo;s Unified Model (UM). This study enables CASIM and SOCRATES to us
 e accelerated multi-core systems for optimal<br />computational performanc
 ...\n\n---------------------\nEnsuring Statistical Reproducibility of Ocea
 n Model Simulations in the Age of Hybrid Computing\n\nMahajan\n\nNovel hig
 h performance computing systems that feature hybrid architectures require 
 large scale code refactoring to unravel underlying exploitable parallelism
 . Such redesign can often be accompanied with machine-precision changes as
  the order of computation cannot always be maintained. For chaotic sy...\n
