SUMMARY:Containers at Exascale for Cosmological Simulations
DESCRIPTION:Minisymposium\n\nContainers at Exascale for Cosmological Simul
 ations\n\nPotter\n\nThe next generation of large-scale cosmology surveys s
 uch as Euclid require, and will continue to require significant computatio
 nal resources both for single "high resolution" simulations such as the Eu
 clid Flagship Simulation series as well as for parameter studies such as E
 uclid Emulator. As we approach the Exascale era, the performance of the co
 des involved in these endeavours must be continually improved and maximize
 d to make the most efficient use of the available resources.  At the 
 same time, container technologies are increasingly used to promote portabi
 lity, reproducibility, and continuous testing and integration. I will disc
 uss my experiences applying container technologies to PKDGRAV3 (a high-per
 formance n-body code) and the impact on performance and the compromises in
 volved.\n\nDomain: CS and Math, Physics
