CPDN has long deadlines because it has correspondingly long crunch times.
An 800 MHz computer with an FPU (and CPDN uses the FPU) takes well in
excess of 9 months to crunch the data running 24/7. A 600 MHz device with
no FPU will not finish within the lifetime of the phone - even running
24/7.
Will this always be true? I cannot be certain - ever is an awfully long
time.
Deadlines vaguely track crunch times on most projects. Long deadlines
usually have correspondingly long

1. Some projects has LONG deadlines - Climate for example.
2. There will be absolutely need for different and smaller units so it may
be counted in few hours / days.
