The simulations finished in september 2003 so there is no monitoring anymore. During the simulations we were able to monitor the simulations via this site. At that moment there were 31 CSM1.4 integrations running at the supercomputer of SARA in Amsterdam. Each integration being a simulation of the earth's climate from 1940-2080.
The pages below contain results of each integration. The plots show statistics about temperature, precipitation and windspeed for each integration for the period 1940 until the current year the integration was in at that moment. They showed the situation of at most 1 hour ago (the plots were automatically updated every hour)
In the optimalization process of the CSM model it appeared to be most efficient to use 8 processors for each ensemble member. We have 256 processors at our disposal on the TERAS supercomputer so we decided to run 31 ensembles simultaneously (31 x 8 = 248). The 8 processors left are used for a tool that reduces the size of the outputfiles. It is not necessary to save all the output of the climate model and there would not be enough space on the TERAS to save it.
The tool also makes plots of the (critical) fields temperature, precipitation and windspeed shown in the webpages above. It plots integrated values of these fields for each member in the experiment during the integration. this way we can easily check whether the output is nonsense or no-nonsense and if necessary decide to abort a particular run.
A simulation of 140 years takes little over a month of wall-clock time. This gives us the opportunity to do 62 (2 x 31) ensembles of 140 year.
