night-time auto-reboot?

[A.J. Rossini]

Our department is picking up a few decent PC's for staff.  I'm
wondering about the current feasibility of auto-booting in and out of
Windows 2000 and Linux on a set schedule (say, out of Windows to Linux
at 8pm, into Windows at 6am, or something like that).  We've got a
small cluster, and this would be just to augment that.

Most of our jobs are migrated via MOSIX, but we are looking at some
PVM/MPI code as well, and with respect to the later, will we have
problems?  (or would it just be a matter of making sure that the
MPI/PVM jobs are initiated as processes on the primary cluster
machines, since they can migrate back to "home" when the augmenting
machines switch over?)

I guess, what I'm looking for is some kind of logic for Lilo, or even
using something like UMSDOS to start up a Linux job (to take over the
system). 

Any experiences?

best,
-tony
