[Opensim-users] Multi-core, multi-threading OpenSim

[Kesick, Nicholas Charles]

It may be in there now, but I see a note for Mono 2.8 (release date to be determined)



Parallel Frameworks:

New runtime ThreadPool implementation, increases scalability and performance of Mono on multi-core systems (done)

Hi all,



A simple and stupid question. I was trying to look for some

information if OpenSim is multi-threaded and able to automatically run

on multiple cores, or if due to some limitations of Mono (unknown to

me), this is impossible. Google seems quiet on this (or I might just

have been unable to trigger the right combination of keywords that

provide me with the answer I need).



If so, it would make more sense to launch multiple separate Mono

instances, each running a set of regions, instead of having just one

instance with all the regions in that server?



What would you recommend as a more reasonable configuration? I usually

have Linux installations with 4 virtual cores, and from visual

observation, only two (sometimes even just one!) is being used all the

time by OpenSim and Robust. Does Mono somehow pre-bind to a single

core and never changes? (In that case, launching multiple OpenSim

instances would all get pre-bound on a single core, thus not really

making any difference?) For a server that is exclusively used for

OpenSim, it seems a waste to let all those cores run idle...



Thanks for any input on this :)



Cheers,



      - Gwyn
