BOF 2: (BATCH SCHEDULING)
use BOINC's reliable mechanism to improve turn around on important workunits
set server parameters to escalate priority of additional results generated for a workunit, these get sent to clients which return work quickly and reliably
tell the hosts to communicate with server every X days
if a host doesn't communicate with the server within that time frame (maybe + Y), good chance it's gone
how can we tell that a computer will be around?
keep track of uptime
many are not around on weekends
