6.6.11 has a bug that if a GPU job is running,and a 2nd GPU job with an earlier deadline arrives, neither job is executed ever. Maybe you get hit by this.
I use a script running in an infinite loop to notify me when this happens. Then a boinc restart fixes it... until next time. Also turning off "leave applications in memory while suspended" in your computing preferences seem to help a bit, but it doesn't solve it completely.

wow. never knew that... i dont see that in my system but that is because i run the cpugpu perl script often to catch random downloads so boinc gets restarted several times an hour.
soon as the scheduler gets fixed ill give the new one a shot :)

On days I work (12 hour shifts) I'm at my computer maybe 3-4 hours, so odds of me catching it is slim, hence I use 6.4.5 for crunching. I just switch to 6.6.11 to download 5-10 days cache, rebrand it all and then back to crunching.

Well, you could use a script to restart boinc automatically when the bug kicks in. I didn't do it because I didn't like too much complexity and at the end I preferred I have the control over boinc restart.

Restarting boinc several times an hour surely squashed that bug. :D

Yesterday, some changes to the scheduler were introduced. The problems I posted above, it seems, were across all platforms as the changes were generic. The battle with task scheduling in boinc is an ongoing and never ending one.
I haven't checked boinc with the new changes to see how it runs. Feel free to check it. At last we'll have a "modern" boinc release with proper multi-gpu support in linux in the next round of "official" releases.

Yes, you have to compile from source.

ok hope i got the right one. never did 'get' what to do with svn there are so many different sources. looks like the one i got was trunk 6.9.0. is that the correct one?
