Model name: CM2.4A18

Coupled climate model.

Component Name Resolution #Processors Throughput (y/d) Data volume (GB/y)
Atmospheric Dynamics FV-LL M90L24: 288x180x24 60 1.5 146
Atmospheric Physics AM2p14
Land LM2 M90: 288x180 60
Ocean MOM4p0 OM3p25: 1440x1070x50 600 1.25
Ice MOM4p0 OM3p25: 1440x1070x50 600 1.25

Notes: The throughput of this model is limited by the throughput of the FV-LL model, which runs on a lat-lon grid and is limited in scalability. The scalability is improved on shared-memory systems by using Persistent Shared-Memory Execution Threads (PSETs), a technology developed on the SGI-Altix platform, and currently being ported to the Cray-XT platform with assistance from Cray Research Inc.

Model name: C360-HiRAM

Coupled land-atmosphere model with ocean boundary conditions supplied by AMIP datasets.

Component Name Resolution #Processors Throughput (y/d) Data volume (GB/y)
Atmospheric Dynamics FV-CS C360L32: 360x360x6x32 1536 1 912
Atmospheric Physics HiRAM
Land LM2 C360: 360x360x6 60
Ocean AMIP
Ice AMIP

Notes: The atmosphere is run on the cubed-sphere grid, This novel grid removes many scalability barriers associated with more conventional grids.
