I would like to look at checkpoint files. Actually, I do not wish to look at the content, but just size, time and date written, etc. What ls -l could tell me.

If I knew the name of it, the locate command could probably find it for me.

Just been digging around, clicking on the task and then properties for the time of the last checkpoint is a clue but looking at one of mine, I am not sure that whichever one it is is the only file modified at that time as a number of files seem to be modified about the time of last checkpoint based on cpu time since it occurred. There are files modified both in the slots directory for the task and in the task directory.

Yes, there are lots of files in use for each model, which is why they need to be given time to be saved before shutting down.

In the "boincdata"/projects/climateprediction.net directory, a file is written with the filename trickle_up_"rest of the filename". It is usually immediately uploaded, unless the communications with the project site has "backed off" because of a communication less than 60 minutes prior. When you know a trickle-up is not too far off, you can "Suspend Network Activity" from boinc manager so you can look at the file before it is uploaded.

Trouble is, I do not wish to see the trickle_up files; I want to see the checkpoint files.

Ahh, I didn't read that very well. Restart files are in the

boincDataDirectory/projects/climateprediction.net/"hadam4ModelName"/dataout

directory. Filename should be like atmos_restart.day
