Noticed recently that my available disk space has been eroding for no apparent reason. Checked BOINCManager\'s disk tab and discovered (after about 5 minutes of spinning beach ball) that CPDN\'s disk usage has ballooned from the already exorbitant 100 MB it started at to 3.7 GB. Is this normal? I don\'t have this kind of disk space to spare long term.

Completed sulphur models take a bit over 2gigs before final compression.
You have a lot of failed models, so you can gain space by deleting the folders for these.
Be careful not to delete the current, or queued up, models. :)

If you have any that completed successfully, you can move the folder(s) to a cd for future reference if you wish.

Thanks for the quick response - turns out that\'s not it, though. The full 3.7 GB is in the folder for my currently running project (the other folders were correctly disposed of by BOINC.) The bulk of it, 3.3 GB, is in the \"tmp\" subfolder. Of what\'s left, 300 MB are in the \"dataout\" subfolder. Should I take it there are temporary files not being properly dealt with?

This is getting tricky, because I\'m not a Mac person, so I\'m not sure what should be in \"tmp\".
This data may be what it is currently working on. You\'ll have to check the model name against some of the files.
The data in \"data out\" may also be current. It is if it is a subfolder of your current model. It will get zipped on model completion.

In Windows, a slab model leaves about 330Megs of zipped data after completion. Only a small amount of data is uploaded, as, when the project started, a lot of people were on dialup.
This remaining data may be asked for by the project researchers if they find the short data interesting. And it can also be used by the participant to study their completed model. This sort of thing is often discussed on the community forum.
Basically:
A) you can move the completed model folder to somewhere outside of BOINC,
B) you can save it to cd (which is what I do),
C) just deleted it if you have no interest in the science.

Thanks again. I think I misspoke though. When I said it was all in the folder for my current project, what I meant was that it was all in the folder for my current <i>model</i>, sulphur_emj7_000682387. All the subfolders I referenced were subfolders under that currently running model, i.e \"sulphur_emj7_000682387/tmp\" and \"sulphur_emj7_000682387/dataout\". All data regarding previous models appears to have been automatically deleted when those models crashed (thanks to the now-fixed FORTRAN library bug).

A bit more information on the \"tmp\" folder. It contains 22,533 files. All except 4 of them have file names of the form \"sulphur_emj7_000682387.0#####.cpdn\", where ##### is a number between 19544 and 42073. They appear to have all been created in sequential order over a 4-day period last week, from the 12th to the 16th. The earliest ones are 152k, gradually rising to 160k apiece by the last ones. Based on the timestep my model is currently on, it looks like each file corresponds to timestep number #####. For whatever reason, the program either stopped creating them or started deleting them at 11 AM on the 16th. Does this give you any other ideas? Again, it looks sort of like the program was just failing to delete its temporary files, but I don\'t know the guts of this thing.

Sounds like you accidentally found the dreaded \'G\' key feature on the 12th :(

It records the model state at every timestep. Closing the graphics window doesn\'t stop the recording - that only happens the next time you hit \'G\' (which you must have done at 11am on the 16th).

You can safely delete the sulphur_emj7_000682387.0#####.cpdn files.

Tolu is going to change the key sequence and add a recording indication to the next application release.

Neat! Thanks. I <i>was</i> screwing around trying to figure out what the graphical modes in the visualizer were...
