[Stackless] is there any detail about eve's stacklessio technology?

[chenmin7249]

AFAIK, erlang achieved true parallel computing which scales very well both horizontally and vertically, actually unless python removes gil, in a predictable time, python is no match for erlang in true huge parallel computing area.


but erlang syntax is just ... too weird, and python fits well in small-medium parallel/event triggered system, and inter-process communication would cost much less than moving from python to erlang, i think that's why python/stackless fit almost all general purpose projects

I am sending this offlist as it is not really stackless related, but feel free to reply on-list if you wish.

I have embedded stackless into a couple of different programs of which it was quite a great fit for, but for servers of anything of this sort I have always had the base system run on Erlang.  As Erlang sounds like the exact fit that CCP is trying to use stackless python for, I am curious how it compares to how an Erlang based system would be.  Do you have any knowledge of the Erlang language and systems to make sure a comparison, or anything I could clarify about it?  I love using Python, but I have never been able to get the performance that I need out of it since I traditionally do massively parallel work and the GIL just... hurts, hence why I just use it as an embedded scripting language for client programs, but not for our server use.

CarbonIO is a proprietary CCP techology.

It is not fundamentally different from stacklessIO, just a rewrite allowing us to implement low level message routing in C, thus bypassing the C/python interface, the GIL and other such things, in certain areas.  Because of its tight integratino to EVE and our Carbon infrastructure, it is unlikely to be made available.

thx very much K, it's very helpful.
BTW, could you please provide more information on the CarbonIO technology? like a http link or company name or something, i'm pretty much interested, thx in adv.

Neiter CarbonIO or StacklessIO are open source.  The latter I always planned to dump out there, and I still may do so when I find the time.

We chose windows because that was the most widely available gaming platform at the time.  The client and the server use the same engine so Windows it is.  In terms of performance it does not really matter what operating system is running.

 

Cheers,

is there any technology detail like papers, blogs about eve's stacklessio technology? is it based on stackless python too like their main game logic?
google only shows the news.
