I think there is a problem with this WU
3/1/2010 6:29:59 AM GPUGRID Restarting task D328-OTTO_HERGflip656-10-100-RND8625_0 using acemd version 671

The progress reaches about 99.712 % and then bounce back to 99.216 %. Again to 99.712 and again to 99.216, and continuously such a way !!! It seems an infinite loop. (other times reaches 99.76 or 99.68 but bounces back to 99.712 - now the elapse is about 29 hours) I decide to abort it!!
GPUGrid is running continuously with no suspension!

Win XP 64b BM 6.10.35 (64b version)
NVidia GT9800

Sorry little error:

(other times reaches 99.76 or 99.68 but bounces back to 99.712 - now the elapse is about 29 hours)

the correct interval is 99.216 --------- 99.76 or 99.68

I've found that for me, the GPUGRID application writes checkpoints for use if it is suspended, but BOINC does not automatically suspend any GPU workunits at all. Instead, it suspends GPU workunits only if the user tells it to.

You still have the other problem of the application having problems going from one checkpoint to the next on that workunit, though. I suspect that it is repeatedly recovering from a checkpoint, then failing to continue through the next two checkpoints properly.
