The three phase \"slab\" model (hadsm3) and four phase Mid-Holocene (hadsm3mh) are choices in your project specific preferences for climateprediction.net.

The Linux versions 5.04, 5.10 and 6.xx will output Error messages at the end of each phase in the terminal window, if you are running boinc from the command line. The error messages will have numerous lines

These are not critical errors and do not affect the output from the model. If you are not running the \"boinc\" executable from the command line, you may not notice these messages at all.
