The only people who should now be running cpdn Classic models are Open University students while they are following the OU Climate Modelling course. Classic has finished as an active research project, so Classic crunchers need to move to boinc-based models.

Minimum computer specifications for current ClimatePrediction models are 1.6GHz CPU and 512Mb RAM. There are other boinc projects with lower minimum specifications.

Anyone needing advice about migrating from Classic to cpdn on boinc should register and post on the cpdn forum.

Or go directly to the boinc download through the Climateprediction front page.
