Hi, my problem is a little hard to explain.

My config :
boinc 6.10.18
win 7 64 bits
Core I7 920
projetcs : climate prdiction, WCG, Virtual Prairie, lhcathome, hydrogenathome

In fact this night, I had a power cut at the house.
This morning my boinc manager only shows me tasks from climate prediction only, instead of tasks from all my projects.
I checked in c:\programdata\boinc\ the boinc data directory and I still see a folder Climate prediction, word community grid, lhc@home, hydrogen@home etc.
Thoses folders ar not empty, we can see files from thoses projects.

Before the powercut, my lists of tasks in boinc manager was full of tasks from WCG and a few of climate prediction.
So why boinc needed this morning to donwload new tasks from climate prediction ? and not working anymore on the others projects ? WCG tasks just desapeared from the boinc manager.

For solution I tried to :
- put a cc_config.xml file with the full path of the boinc data folder and force to read the file in the boinc manager. No changes.
- I uninstall boinc and reinstall it.

Any idea how I can force boinc to check thoses folders to see if tasks are still in those ?

Thanks

I checked in c:\programdata\boinc\ the boinc data directory

Is that really the (current) BOINC data directory as listed in the Messages tab of BOINC manager?

Gruß,
Gundolf

I see my projects on boinc manager, but no tasks exept the new ones from climate prediction.

I reseted my projects, and it works now.
I don't know why I lost my previous tasks, if you have an idea, please give it.

Thanks

The science apps don't like having the "plug pulled" unexpectedly. BOINC needs a small amount of time to shut down gracefully, and a power failure doesn't allow for that.
It's the same if you just turn off the computer without first closing BOINC.
CRASH! No tasks left. (Especially with climate models.)

Climate models, for instance, use dozens of files. If some of these are being written to at the time of the failure, then it doesn't matter what's in either of the client state files. Even worse when the app is creating one of the upload zip files.

The plug pull cases whilst the client_state.xml write had not finished I thought were covered by restoring the client_state_prev.xml. If not, then what's the point of BOINC making backups?

I just exited BOINC, removed my client_state.xml file and restarted BOINC. It picked up on the client_state_prev.xml file and made a new copy, naming that one client_state.xml

So that works.

BOINC checks the start and end contents of the CS file, not anything in between. Still, to lose all work for all projects must've meant that all those were written to at the time of the power outage. A little unbelievable, although not impossible on an 8 core CPU (OK, 4 core, with hyperthreading ;-)).

@sekaiji, could you please check in Windows Event Log if Windows did a chkdsk upon restart?

Considering CPDN is on board, venture to think there were more tasks in the Tasks window then there were cores to handle them. sekaiji will surely confirm this one way or the other.

Or memory. Les, how much does one Hadam3p version 614 take up?

I'm not sure about that; I'll have to ask.
Vague guess - 500-700 Megs? Plus more for graphics if they were open at the time.

I've got two on the go at the moment. About 100MB on disk in the project directory, 300MB - 350MB for each model in their own subdirectory.

Each using about 215MB of RAM while running, graphics not possible on this Vista32 host.

Ah - got one on XP too. About 25MB RAM for graphics.

Obvious, of course. Just download one and see.
Similar to Richard - 222MB; graphics jumping between 18.4MB and 34.2MB.

So about 250Megs of ram with graphics.
