A resend of a lost task is not the same as a fresh work assignment.  These 
tasks has already been assigned to that device by the server at some previous 
time, and succeeded in getting lost in transit.  They will not be reassigned to 
a different computing device on your computer.

Subject: [boinc_dev] Seti Beta scheduler resends work to a GPU that didn't ask 
for it.

I get the impression that the present scheduler is broken in some 
respect, on both my i7-2600K/GTX460/HD7770 and my E8500/GTX9800+ hosts 
they will request work for one device, then get sent work for another 
device that wasn't requesting work:

I did initially report it on Seti Beta:


http://setiweb.ssl.berkeley.edu/beta/forum_thread.php?id=1950&postid=44291



Turning off Use Nvidia GPU in the project preferences stops work being 
resent to the Nvidia GPU when it wasn't asking for it,
i can then get CPU work resent to the ATI GPU when it wasn't 
asking for it instead,
