Hum, would a 6 piston version work as well as a 3 piston one from a efficiency standpoint? Possibly with different turbos or some such?

Simultaneous multithreading you mean ;-) (Hyper threading is just a brand name from Intel for a previously existing technology damned SMT that existed on other CPUs before I tel used it, although theirs where the first x86 implementation and the first intended for home computers).

@BeRAd427 That would be weird... I guess you could have six cylinders with a gap between them and have a continuous piston between the two. It might arguably be considered two pistons instead of one, but if it's a single piece of metal you could probably get away with calling it a single piston. Then it would have to have some way of transferring energy, sideways out to a shaft somewhere. You can't have a crack shaft between the two piston heads as you probably couldn't call it a single piston then... It would be a really really inefficient engine most likely, and no one would do this for any other reason then just showing that it can be done...

@panda4247 That might be a better design then what I had in mind, I was thinking a lever instead...

@jimbronson687 It's a bit more then that. The first threads where. But as computer technology developed and especially out of order execution became possible a CPU could execute instructions from a different thread entirely while running code from the first thread. You can actually do it with a in order CPU too keeping more of the CPUs execution resources occupied, but chances are far higher then that there's just no instruction in either thread able to utilize the available resources or that one thread has to wait for the other thread to no longer need a specific resource in a given clock cycle.

@lelsewherelelsewhere9435 People calling SMT for hyperthrading is a bit of a pet peeve of mine. The technology is named simultaneous multithreading while "hyperthrading" is just Intels first implementation of it (others had done it before Intel).

@sirprise9548 Thank you. :-D

@dantemartinez5494 I think that it's possible, just really, really inefficient. If you have two opposing piston heads connected by a metal rod that's all a single piece of metal can't you argue that it's just a single piston facing two ways? Or even a piston that's just a single solid block of metal. You can divide the cylinders in two by having a opening in the middle between them and design the engine to have the piston move between them or increase and decrease the amount inside each end. It's obvious a bad idea, but it should be possible at least.

@cerberus1166 Yeah, no... That last comment of yours is just wrong, and you know it given your earlier comments in this thread. The cylinders are the holes, not the pistons or ends of the holes, just the holes themselves.
