SMart Spice Simulation Parallelization

[fioren]

Hello,


Does anyone have any ideas on how to organize a bunch of disjoined
windows sim machines as to achieve optimal time-of-simulation results?
I know smart spice hasdata parallelization capabilities but I am not
sure whether it is available for windows machines. Is there some
software that can facilitate and decrease simulation time? Organize the
machines under a common server and run something there, perhaps...Task
parallelizatiion vs data parallelization? Any help would be
appreciated. Thanks

What is it that you are trying to accomplish?

Well, I am trying to reduce the simulation time in any way possible:

What is the optimal setup (in terms of windows sim machines and
SmartSpice simulators) to eliminate the need for separate individual
remote desktop log-in on each machine and synchronize the machines so
that the same circuit can be run on separate machines(several CPU's)
but with different parameters, corners, etc. and the machines are
synced such that ideally SmartSpice can transfer, re-use data between
the sims (naturally a slow communication channel here would be an
overhead in sim time)?

Ideally this is the goal, a designer logs on to a single
machine/server, and specifies a circuit (testbench) to be simulated
with a bunch simulations for various corners e.g.; the server then
checks which of its designated sub-machines are free (!), notifiest
SmartSpice so it can start simulating on them. Now as more machines
become free, SmartSpice sends different parts of the testbench to
different machines to be simulated so in essence we have parallel sims
of the same circuit but on different machines. Now add in more
cicuits/testbenches as well so we have a machine that perhaps might
simulate like this: tt circuit A, ss Circuit B, ff circuit C, ss
Circuit A, etc. - (some kind of priority here) Something like
that... Does that automation seem possible on windows machines and
what would it require? Thanks

Does SmartSpice support such multiprocessing? I don't think so.
