Description

In this paper, we explore the challenges of running the current version (v1.2.2) of
Community Earth System Model (CESM) Simulation on Juqueen. We present a set of
workarounds for the Juqueen supercomputer that enables massively parallel executions and
demonstrate scalability up to 3024 CPU-cores.
