River,
THANK YOU for your elaborate instructions. With school and all, I just don't have time to worry about how to fix crashing work units. I will save your instructions in my e mail account in case I need it......... I thought It would be best to crunch for this project (LHC), and when there is no work, help out ufluids. It is an alpha project, however they seemed to have ironed out most of the work unit issues, unlike Rosetta. Now that I have a DSL line, I also donate my bandwidth to http://www.majestic12.co.uk/

I got a computational error 35% of the way on a CPDN workunit. How do I restore that workunit? I am running Boinc 4.45 on XP. 2.26GHz processor
As long as you made a backup of BOINC after you downloaded the unit and before that happened all you have to do is shut down BOINC and restore tha backup. But most only do that for CPDN as they have a lot of crashes. If you have a backup from that time frame b sure not to rerun the ones that were already run, and you will louse others that you downloaded after the backup. Not worth the work for one unit, just accept the fact that it is lost forever from your system.
I disagree, Ray. It *is* worth the effort to save just one CPDN workunit - and furthermore the CPDN prject people positively encourage users to do this.
If you did not backup that folder before, it is too late.
It you did backup the folder, and if you have any non-CPDN work held locally, proceed as follows:
1) set no more work on all projects, incuding CPDN
2) abort any new CPDN wu that was downloaded automatically and has hardly started (reason it will be sitting around for a long time while your reurrescted one crunches, it is better for the project to allow another user tog et started on it)
3) let the work on all other projects complete and upload and report
4) when you have a client running with no work, stop BOINC
5) copy the backed up folder onto the BOINC folder
6) restart BOINC
7) reset all projects except CPDN (this makes sure you do not re-run work from the other projects)
If you only have CPDN running on that box, steps 5 & 6 should be enough.
To backup the BOINC folder on windows there are two methods
A) right-click the folder, copy; go somewhere else and paste - all the files under the folder will get copied, this may take some time
B) if you have winzip, or if you know how to use the zipping facility built into XP, you can create a zipped archive of the entire BOINC folder.
To backup from Linux GUI, you can proeceed as for windows (A).
To backup from Linux command line, use tar - man tar will tell you exactly which switches to use to create a zipped archive.
Hope that helps,
River~~
