One is based on 4.0-HEAD and the other one is based on the actual trunk (r13721). I ran the simulations for 1 year without changing anything in the reference namelists. I used 40 processors on 1 core of Jean-Zay machine in attached mode (monthly outputs). Results are worrying. '''4.0-HEAD = 4h cpu time''' '''trunk = 12h cpu time''' Time is tripled in the trunk. The timing.output file indicates an issue with diaptr that has been reported recently (ticket #2559). But a number of other routines are also super slow (e.g. sbc, zdf_phy, icb_stp etc). I'll try to attach the logs (if I find the attachement button) I am either missing something or we are facing a huge problem here. {{{#!imagebox [[Image(Capture d’écran 2020-11-04 à 12.51.26.png,45%,align=left )]] [[Image(Capture d’écran 2020-11-04 à 12.52.08.png,45%,align=right)]] }}} " Defect closed low MULTIPLE trunk critical fixed smasson
