I am running a simulation that takes forever to be completed! It has some switched-cap circuits inside and currently I use moderate simulation and ASP is also enabled, with 16 threads and 24 cores. I wonder if there is any option to break the simulation into smaller parts and use several computers to run parallel simulation.
I did read your question and tried to find a different solution which even might been faster.
AFAIK, Spectre APS will run parallel on cores/threads ( which you already do) but not over different machines.
