Re: OT - united devices



-----BEGIN PGP SIGNED MESSAGE-----

I had a play around with the UD stuff, and found it to be a pain to
run on low-end systems or in my case a dual-boot laptop.

Once the program has started work on a molecule (or group of
molecules) you have to let is finish that bit.. If you shutdown or
switch the system off, the software does NOT checkpoint its current
position so has to restart calculating from the beginning of that
molecule (or group) next time the software is started. 

Some of the molecule groups can take for ever to run.  As an
experiment I left the software running on a laptop (uninterupted) and
one particular group ran for 6 hours until I got fed up of it.  The
next day I let the software run as long as it could, and the
conformer count was reset to 0 and it restarted that group and went
on for 15 hours (I went to bed and left it...)  The following morning
I looked at the program and found it had only done 1 percent of the
data....

Over the next hour or so whilst I had my breakfast the software ran
through another 4 percent of the data..

If you run your system for 24hours every day without interruption, or
if you have a beefy system you might get through a data unit in one
go.  With it on a laptop, your best bet would be to 'suspend' the
system rather than completely shutting down.

When the current data unit is finished on my laptop, I will be
uninstalling the software to give it something more important to do..
 (SETI, RC5 or just playing solitare :-) )
