How do you set the deadlines for the work units? |

The following is an excerpt from Stanford's F@H FAQ on how deadlines are determined.
Each work unit is benchmarked on a dedicated 2.8 GHz Pentium 4 machine with SSE2 disabled. Next, we apply this equation
timeout = 20 * (daysPerWU) + 2
deadline = max(30*(daysPerWU) + 2,10)
where daysPerWU is the number of days it took to complete the unit. The
"+2" days is there to give an additional buffer for fast WUs (to allow
for servers down, etc). If 30*daysPerWU is less than 10 days, we set
the deadline to 10 days, as a minimum time for all projects. The
timeout is the time at which the WU is resent to another client and the
deadline is the last time which we will give stats credit for the WU.
Occasionally, deadlines may be set shorter or longer than the above
calculation indicates, but the reason for having deadlines at all is
that the sooner we get back work units, the sooner we can put the
results to good use. The assignment server does take machine
performance into account in making assignments, thereby allowing slower
machines to receive more appropriate work units.
