Hi

It'd be beneficial if BOINC automatically increased the cache size if it regularly runs out of work due to no internet connection being avaialble.

For me this would be useful as I have a couple of machines with intermittent connections, which regularly run out of work unfortunatley. There must be thousands of machines out there with the same issue, which aren't monitored by their owners, or aren't reachable.

I can't change the BOINC preferences as they're set up appropriately for other machines (only having three profiles available is another problem, but that's another issue).

Thanks
Danny

This would add unnecessary complication to Boinc and could lead to all kinds of other problems involving late return of work.

The simplest way to overcome your problem is to have a host specific General preference. Boinc already provides for this by allowing the use of a Preferences override file as in this example.
The simplest way to create this file is to make a copy of your global_prefs.xml and naming it global_prefs_override.xml. Edit the global_prefs_override.xml file by deleting the venue section and changing the value for
<work_buf_min_days>0.1</work_buf_min_days> for the specific host.

I know about the override file, and have one set up on a few machines. Its a work-around though rather than a solution. There are thousands of computers out there that've had BOINC installed and then no more attention will be paid - install and forget - as BOINC should be. Many of these machines will sit idle if they have an intermittent internet connnection.

Maybe this would need to be implemented after a purge function (which I've mentioned here (and I think FluffyChicken has too) and on Rom Walton's blog) then it would have no negative effect on deadlines.
