You are asking for help from the BOINC folks, on a linux list?  Rotsa ruck.
I was in the top 5000 when it was SETI@home, but they let some windows 
folks in & the next thing I knew SETI was shut down unless you ran it via 
the BOINC manager.  But the BOINC thing never learned about nice, and just 
took over the machine so badly I couldn't even type an email.  I worked for 
several days on a wrapper that did use nice, but their next packet 
transition always managed to defeat it.  When I complained, I was told to 
use windows!  Since it was my machine, not theirs, I nuked it off the 
system.

IMO, if they want to use my spare cpu cycles, then they can make an effort 
to get along with linux.  Telling me, when I complained, to use windows, 
was the last straw.

Cheers, Gene
