AROS hosted on Haiku still would run single-threaded. Once AROS Hosted on Linux gets multithreaded, then we can talk about AROS on Haiku. (BTW, I kind of like Haiku myself!) |

Absolutely, there should be more then enough horsepower in a reasonable speed P4 to keep Haiku in more then enough resources for a snappy end user experience. My point is when a app/game that was designed for multicore is ported into a single core system (or the OS can only access one core in a multicore CPU because it's not SMP) , the end user experience is not going is not going to be a happy one. Clearly I am not talking about app/games that use trivial amount of system resources.

I didn't mean hosted would be multithreaded, I was just referring to porting AROS-hosted "as is" to Haiku. |

A heavily multithreaded game/app written using the BeAPI is going to run more smoothly on a single core machine than a multithreaded app/game written using Windows/Linux APIs on the same hardware though, but I get your point. |

That depends... Current operating systems are actually becoming less symmetric in order to increase performance and power efficiency. Not even a multi-core system is fully symmetric after all.Last edited by megol on 22-Sep-2013 at 10:12 PM.

Having an OS to use AMP means each core has it's own kernel that is largely unaware of the other cores. 10 years ago you could get away with it when systems were dual CPUs (vs today's common multi core), but today's standards set firmly at the SMP level.
