Has it always done this? or is it a new core feature?

well it's always written checkpoints though how often and where does depend on the core it's using

the Tinker core only writes checkpoints when it's completed a frame (hence large Tinker WUs having 400 frames) - the gromacs core changed that by allowing you to set a timered checkpointing interval of between 5-30 mins (looks like yours is set to 15 mins here)

so yep all normal - though I thought it was meant to reset the clock each frame and write 15mins after the "Writing local files" message - I'll have a looky at mine and see

what core is this unit using? :confused:

edit: you may not have seen the checkpointing messages before if you used not to have the "-verbosity 9" switch

I get 'Writing checkpoint files' all the time on the older machines in my office - nothing to worry about (could up the timer interval to 30 min via -configonly switch on a shortcut - see set up faq)

keep crunching

edit: Rich, does the -verbosity 9 switch switch this timer off then?

the verbosity switch just controls how much information is written to the log. You don't need it on 9 - it's just most informative.

Amber core.

ahh that makes sense then - the Gromacs and DoubleGromacs both reset the clock when they finish a frame
