Re: Parallel computing?

Actually Linux supports suspend well, it just depends on the host hardware.
My Cannon Innova-book will suspend/sleep/etc.. linux all day long multiple
of times. While My Toshiba Sattelite Pro will not. I tracked it down to the
fact that the Cannon does the suspend/sleep in hardware entirely.. when
it's time to "hibernate" it writes the contents of ram to a track on the
HDD and shuts down. while the Toshiba requires software drivers, It tries
to talk to the OS... and has a lag time from the write to killing the OS so
file states are not exactly the same. Many newer systems use this soft
setup because it's cheaper. And we all know that cheaper is always better
for causing headaches.
