29.6.2011 6:49:49 GPUGRID Restarting task 4-KASHIF_HIVPR_n1_bound_so_ba2_308-23-100-RND5975_2 using acemd2 version 614
29.6.2011 9:26:34 GPUGRID Started download of I71R1-GIANNI_KKFREE4-7-LICENSE
29.6.2011 9:26:47 GPUGRID Finished download of I71R1-GIANNI_KKFREE4-7-I71R1-GIANNI_KKFREE4-6-10-RND1717_7
29.6.2011 9:26:54 GPUGRID Starting I71R1-GIANNI_KKFREE4-7-10-RND1717_1

At 9:26 newly downloaded long-run task was started even that running (short-run) task was not finished yet! Only 96% was done.

I think its because long-run has "higher priority" in boinc.

Thanks for reporting this.

There are three possible configurations that could prevent this:
Keep your cache at zero (not really recommended).
Only run either long or normal tasks, but not both, http://www.gpugrid.net/prefs.php?subset=project.
In Boinc Manager, Advanced View, open Preferences from the menu (under Advanced for 6.10.60). Set the value for Switch between applications every to 999 minutes; If you run a mix of long and short tasks, and if the short tasks can finish within 16.6h (should on a GTX470) then Boinc won't switch and start running a long task. Even a long task with higher priority should not start before an existing long task finishes (the longest long-tasks take 10h on my GTX470's).
