SUMMARY:Study of the Recent Developments around the PaStiX Solver for the 
 EoCoE Project: Distributed Memory, Runtime Systems, and Low-Rank
DESCRIPTION:Minisymposium\n\nStudy of the Recent Developments around the P
 aStiX Solver for the EoCoE Project: Distributed Memory, Runtime Systems, a
 nd Low-Rank\n\nDelarue, Faverge, Korkmaz, Pichon, Ramet\n\nAs the core of 
 a large number of simulation tools, the resolution of large linear systems
  often represents the dominant part of the computing time. Massively paral
 lel versions are needed to maintain advances in multi-physics and multi-sc
 ale simulations, especially when targeting exascale platforms. The aim is 
 therefore to address the major challenge of designing and building numeric
 ally robust solvers on runtime systems that can scale up and push back the
  limits of existing industrial codes of the EoCoE project. In this talk, w
 e will study the recent changes made to the solver PaStiX with matrices is
 sued from the project such as the block low-rank compression factorization
 , the capacity to exploit modern GPU accelerators through runtime systems,
  and the scalability on distributed memory.\n\nDomain: CS and Math, Emergi
 ng Applications, Solid Earth Dynamics, Engineering
