Lately I see workunits completing in a matter of seconds in stead of the normal times I usually see on my PC's. I have found this behaviour on different PC's, even after resetting the project. Is this normal behaviour or is something serious at hand?

I am running multiple projects and my BOINC version is 5.10.28 on all PC's. OS is Windows XP with the latest updates. Windows event logs are clean, or have warnings/errors not related to BOINC and Sixtrack.

System configs:
1) HP XW6000 workstation, 2x 2,4 GHz Xeons, 4GB ECC REG memory, 2x SCSI harddisks, nVidia Quadro 980 XGL gfx card

2) Dell Precision 450 workstation, 2x 2,4 GHz Xeons (low voltage models), 2GB DDR memory (non ECC, non REG), nVidia Quadro 980 XGL gfx card, 120GB IDE harddisk

3) HP XW6200 workstation motherboard with 2x 3,0GHz Xeons (800MHz FSB), 2GB ECC REG memory, Asus ATI X850 Extreme gfx card, 160 GB SATA harddisk


Here is a copy of a small part of the BOINC log:

If it is a problem, hope this info helps.

The results I've had a quick look at appear normal, all your fellow crunchers returned them with a very short run time as well. This is normally caused by the magnet configuration being simulated being unstable and the beam failing as a result.

Hope this helps

Thanks for the information. Won't report them again and will continue crunching future wu's when they are available. :)
