Hi Mysteron, i'll try some a bit later for you & see what happens with checkpointing. The one's i'm crunching at the moment have been going for between 4 - 6hrs + so i'm not keen to see if I loose all that time during a test re-start.
Mine also go to 100% complete then crunch on for a while, no biggie really for me.
Yea leaving Windows auto-update on is bad news for boinc in general, I just let mine auto download & I install when I have the time.
On my slightly OC'd i7 3770 they take around +/- 9 hours each (GSCE-SV v1.05) on win 7. On linux machines they seem to be taking half that time or less, 4 hrs, so they done a lousy job with the windows app but good news for for Linux users.
The weird engines WU's take about 1min & the ALX's take 10min's. Havn't done any of the Shor's Algorithm yet.(no work)
I'll post the results of checkpoint test later tonight when I clear the decks a bit.
Cheers JN
EDIT: Like you my GSCE-SV WU's seemed to restart from scratch, but apparently it's a wrapper problem similar to what POGS does.
This is a quote from Oproject admin
--------
QUOTE: "Checkpoints are performed but are not visible through the wrapper.
After discontinuation of the application, program is executed from the checkpoint. Execution time is counted only after the last run of application.
The progress bar does not work properly.
This is wrapper problem. I'm going to improve (several days)."

This post was from last year so I presume it's still the same deal. He says in another post it checkpoints every 2mins?
Hope any of this is of help..
