Climate Dynamics and Energy         
Feedbacks Group (CDEFG)  


The group uses a 192-processor (24 nodes, 2 Intel Xeon E5420 Quad-core 2.50GHz CPU and 8GB RAM per node, InfiniBand DDR network) Linux cluster.

Using about 10 nodes, we can run 1 month of CCSM at T85_xg1v3 resolution in 40 minutes. Using only 1 node, it takes ~3 hours. Depending on whether we have alot of ensemble members to run or we need a fewer number done quickly, we modify the number of nodes accordingly. Talk to Karen if you'd like more benchmark numbers.
