[Radiance-general] Re: calculation consistency & notebook "sleep"?

[Greg Ward]

Sleep mode should not affect a background (or foreground) calculation 
in any way.  The processor picks up where it left off, and the only 
thing that has really changed as far as the programs can tell is the 
system clock.  If reporting is switched on in rpict, you will see under 
the real time section that you have quite a bit of unaccounted time in 
the calculation, but the results won't be affected.
