how much GAUs will be cost for running CCSM3?

[tao_zhang@noaa_gov]

Dear sir/madam,

I am asking how much GAUs will be cost at running a fully active T42_gx1v3 b30.004 control run of CCSM3 in bluesky for one year intergration?
Also, how much will be cost at running stand-alone POP ocean model for one year integration?
I am applying for the computing time, your response is greatly appreciated.
Thanks,

The charges incurred by the T42_gx1v3 fully-coupled CCSM3.0 vary, depending on the processor count, processor disttribution, and the charging (queue) factor. The following information is a copy of an internal cseg document that will provide you with the information that you need to figure your costs for this setup. (Unfortunately, this forum does not preserve the formatting, but you can extract the information that you need with a bit of effort).

Note that you can set up the model run to maximize throughput (column 3) or to minimize cost (column 2).
