The Blue Gene/P is a supercomputer "The Blue Gene at Argonne National Lab runs over 250,000 processors using normal data center air conditioning, grouped in 72 racks/cabinets connected by a high-speed optical network[1]" Sooo how many cars would it be able to run in BeamNG? Around 300,000 at once? That would be one huge demolition derby You take a guess
as much as it would take to max out 4gb of ram since beamng is 32bit right now. I think the dev version is 64bit (??)
0. BeamNG is for windows on x86 processors. Blue Gene uses Cyclops64 which itself is a subset of PowerPC. Individually its processors arent really that powerful, it just has loads of them.
