Compute Error

(moderation:
I read through a few of the compute errors already posted, and I'm uncertain as to what precisely is the cause of this problem. It does slightly annoy me as I have *just* started doing this, so my inability to contribute is aggravating.
Anyhow, that aside it reports this:
2008-09-20 23:40:12.3593 [normal]: Start of BOINC application '..\..\projects\einstein.phys.uwm.edu\einstein_S5R4_6.04_windows_intelx86_1.exe'.
Can't acquire lockfile - exiting

It proceeds to report that for several thousand lines it seems, then returns a compute error. As to what it might be, I'm uncertain. Any help would be appreciated, and I thank everyone for their time.

I looked at your computer and the workunits and it seems you are using Boinc 6.2.18 on XP SP 2. The file locking and directory not found sound to me like einstein can't find the directory where the data files are located. The 6x version has had some problems and you might want to go back to the previous version 5.10.45. It can be found Here.
Maybe someone who knows more can give specifics though.

Hi!
The "can't aquire lockfile" problem under Windows is very often related to the CPU throttling feature. If you have configured BOINC to use only < 100% of your CPU, BOINC will insert frequent pauses into the computation but this seems to work less than perfectly on several hosts.
It should be worthwhile to run BOINC with 100% CPU configured in the web interface and see what happens.

I'll go ahead and set it to 100% and see if it reports the same problems. If the CPU throttling is indeed the issue, I'm unsure if going to a previous version may fix that.
Seems you nailed the problem

Seems you nailed the problem on the head Bikeman. It's working fine now. Thank you both for your help.

I believe that this is all you need to do to solve the problem. Once the BOINC Devs fix the issue, you should be able to upgrade to the fixed BOINC and then use CPU throttling.
You would fix the problem if you went back to a version of BOINC before throttling was introduced :-). You'd probably be better off just leaving BOINC where it is and simply not using throttling for the moment.
You may get more information by doing a search for terms like "throttling" and "lockfile" on the BOINC boards. It's a BOINC problem and probably not related to any individual project's apps.
Cheers,

If the problem is inside the BOINC code that gets linked into the science app, we would have to provide a new app version, tho :-(. We'll see.
But anyway, the Windows app should get an update anyway when the compilation under a new compiler will work, so ideally the lockfile problem and the performance gap to Linux & OS X could all be fixed with a single new app, provided the fix arrives in time.

Hi I had the same problem, XP_SP3, Boinc6.2.18 and E7200 intel procesor, rosetta and einstein are going down, but on other computer (XP_SP3, T7300, 5.10.20) is everything OK... so I try downgrade...
