CCP Curt knows you love big technical blogs and brings us a great dev blog on CarbonIO and how we are improving EVE on the network level.

Seriously nice blog and some great info. And enough graphs to appease my graph-throne <3

Awesome dev blog. I can't wait to see the results when the tech benefits of CarbonIO/BlueNet really start to be taken advantage of.

so basically EVE is finally getting truely multithreated on the server side, sweet. any chance the code will ever become fully multithreated? and what about this being added on the client?

I'm going to preface this post with a disclaimer. I've never used python, never used any programming in the massive scale that you have, and many people here, especially CCP employee's, are much smarter than I.
I have what some would consider a basic question... why python? I've heard complaints about it left right and center, but people still use it.
Why not make all of the software in C++ or any of the other languages out there? What does python offer that C++ doesn't or even Visual C#?
Thought I'd start the flame war and my education.

What was happening at the four peaks of the CPU% per user graph where the CarbonIO spiked much higher than the original StacklessIO?

And here we were, thinking Incarna would hurt performance. Nice work!
Should be interesting to see how much this affects large battles.

Ooooh...two tech pron Dev blogs in less than 7 days! I'll have to read this one again after my brain again re-solidifies, but the first read through was exciting. Can't wait to see what this does to TQ in the wild.

Looking good finally moving away from Python with code that does not "have" to be in python. I have nothing against python in and of it self but for much of the work that you guys have it do it simply is not the best suited. Using C++ and optimizing the hell out of it will help a lot. 
Now the only thing left is to see about getting stackless to efficiently work on multiple cores  if you guys can manage that EVE will finally be able to deal with a 10k fleet battle without flinching or having your poor hamsters going on strike while demanding Segways. 
-------------------------------------------
Should you disagree with me, well I guess that is because I disagree with you. If you have a problem with that please feel free not to tell me. |

As I understand it, it's a pretty simple and sensible reason...it's faster to develop in Python than it is in C++. This isn't a question of skillsets, but more of dealing with the language itself. Python is a higher level language and so many of the necessities of dealing with C++ don't exist in Python, making developing a much easier thing to do.
C++ was also developing in the late 70's....there's been some advances in programming since then.
With that ease of development come some costs...these are likely the negatives you hear about. For CCP, and for others, the costs are worth the benefits.

Is BlueNet going to be available for the Incarna release, or just CarbonIO?
When are you going to "publish" BlueNet data?
Looking at the graphs on CarbonIO (Red) versus the StacklessIO (Blue) there are some very significant spikes in the CarbonIO CPU usage (brief though they may be, they are far above StacklessIO peaks). Have you investigated those causes? What affect on cluster performance would that cause (i.e. laggyness)?

I think, back in the day when the development of EVE started, python was chosen because it was easier to learn than C++. New employees would have fewer difficulties to get used to the code.
The reason why they aren't just replacing the python code with C++ code is, that it would mean a tremendous amount of work to rewrite all these lines of code.
Another point is that all the python code works, as it is right now. Rewriting it in C++ means that a lot of bugs would slip into the code. Basically tested software if better as untested software, right?
So, they are only rewriting the python code when they are required to change it anyway.

Most likely, python wasn't chosen because it is easier to learn, but rather because it is easier and faster to write code. A relatively simple task in Python which requires only one line of code may require hours of coding and debugging in C++.
The idea is that an hour of programming time is worth FAR more than a couple CPU cycles. Higher level programming languages are better business than lower level programming languages.

Whoa, wait a moment! Where did that one come from? I heard no mention of this in any prior devblogs, and not in the fanfest coverage either And yet, this is the kind of thing people will frantically gobble up, the kind of thing everyone wants to read.
When are which parts of this getting enabled? Is that an official feature of the Incarna expansion, or just something that happened to be ready at the same time? What are you hoping to do with this technology in the future?

It's exceedingly unlikely that the server code will be come fully multithreaded, as we do not have any intention of abandoning Python for game logic code and other high-level constructs. What BlueNet does allow for us to do is to take the lower level packet-slinging systems and spread them wide - something Gridlock has on its plate to do in the not-too-distant future for flying in space and the Incarna guys have already been doing for the walking around business.
CarbonIO has not been turned on for the client as yet, but since the client doesn't sling packets for a living that's not a big deal. It will need to be activated before BlueNet is leveraged at all, so you can expect it to happen before the multi-player Incarna release.

It more-or-less won't until we over in Gridlock get about leveraging it as mentioned above.

Players of many other games are happy to see new "content" that they would have to pay for, while EVE nerds, myself included, just love to see technical wall of text like this one. It tells something about the community and why we like spending time in a huge, confusing game with steep learning curve

Graphs. So pretty. This leaves me wondering if someone, somewhere in the near future is going to rewrite the GIL so that it can send processes to other cores/CPUs to be run, rather than keep them all on the same core. But... I don't know much of anything about coding so, to whoever explains why this is a dumb idea, be nice please.
This signature is useless, but it is red.

wow stealth server patch.
One question I have is whether the python develpment that CCP has done is getting any recognition/use in the larger python community. Are all of these advances only usefull in EVE or are they usefull in other places too.
