Change the EVE client to work as distributed computing so Jita traders and AFK people make the dirty job.

Well, at the time that CCP was discussing it at Fanfest last year, Intel had this system under really tight raps.

Recently however they have relaxed the NDA and we are now allowed to publicly disclose the details on the box in general terms.

Here is the box in question : Monster Toy

and it is making use of Intel's beast of a proc running at 4.4 Ghz (air cooled) aka : Intel Xeon X5698 4.4 GHz


Take a wild guess who I work for :)

Cheers.


Looks pretty damn good, unfortunately I work for a competing manufacturer so errrrr.... forget what I just said ;)

Thinking I need to find an excuse to get a crazy OC cpu for our R&D guys, 4.4GHz is pretty tame though understand that you would have trouble getting a reliable rig at a higher clock. Then again buy two and pop in to HA :-D

So, looking at the tama graph... its running on the supernode with +80% over regular dedicated nodes.

Which would put a regular node's 100% mark at around 55% of the supernode graph. So, had this not been on the node it was, there would have been constant 100% utilization for an hour between 19:30 and 20:30?


So, looking the CCP GingerDude post.

I would like to know how that would go on a normalo not reinforced cluster... Especially with time Dillation in action

If you're going to use liquid to cool the cpu and motherboard, use mineral spirits. Its doesn't conduct electricity and is an excellent heat transfering medium.

Some days you're the bug, and some days your the windscreen.                   And some days, you're just a man with a gun.

Not that i know the stuff you talking about, but cooling liquids need more properties besides thermal conductivity and electric insulation. Just to make an example, you don't want corrosion, you don't want heat to create boiling micro pockets. The later freeing gass from the liquid that would very locally kill thermal conductivity. Just saying things are more complex :)

I am serious!

we thought about trying to get some co-workers to drink it, saying it was Quafe Zero, but someone talked us out of it for some crazy reason (was likely for the best).

But the liquid is ThermoChill EC6 UV Blue and we had 2 independent loops. CPU was on it's own and the motherboard/ram were on the other loop.

Stats from the web:

• Pre-mixed with no need for additional additives
• Electrical Conductivity <2µS/cm at 24C *
• Non-Toxic and RoHS Compliant

• Freezing Point - 6C
• 85% Bio-degradable Within 30 Days

• Shelf Stable UV Reactive Dyes of up to 2 years

• EC6 is a true Eco Friendly Product

Also, while we had a ton of fun building this machine, others didn't quite enjoy it as much :) Our area backs onto the the maintenance guys room and they had a few spare tables where we could setup for the build. And even though they're no strangers to loud noise this thing was another level all together!

We had 6 insanely loud fans pulling air in/across the dual 320mm rads and had it running benchmarks for days. Before long we started to fear they would sabotage the project in order to protect their hearing/sanity :)

(Each of the fans put out over 200 CFM @ 6000 RPM and over 60 dB)

Loving these tech blogs.

Keep up the good work

So, just what IS the coolant for that liquid cooler?Big smile


Why, I would have thought that was obvious. Hamster juice ofc Smile


Juice made from the dead Hamsters? WTB Red Pill Big smile

Good to finally see how all those small improvements kick in in one place.

Why is the hardware such a secret? The processor of which you speak is public knowledge.

Edit: As are at least two of the servers that I can buy it in...

In large fleet fights FPS generally drops below an acceptable amount if I zoom in while having graphic settings maxed. What hardware do I have to buy to keep FPS high in those situations? My Computer has 8GB RAM, a Quad Core CPU @2500MHz and an ATI Radeon 5780. I guess the graphic card is the problem? Or is it because EVE is limited to 2GB RAM? Is it possible at all to have high FPS in those situations even with the latest and best hardware?

As long as FTC is considering to ban any HFT, Intel & IBM will have to put those CPUs to some better use Lol

Anyway, good job, good achievement, but I hope you will not give up on the idea of researching/developing multi-threaded server code as a long-term solution?

P.S. Optimizing the client is always a good idea :-)

just because something has a name (X5698) doesn't mean it's publicly available or that a customer is allowed to repeat what it is they're using. it's very possible ccp is contractually obliged to be coy about a processor the world got wind of 9 months ago but that isn't in public channels and they have.

pretty painful how intel hands out cheap fast overclocks like crazy on air gear, then makes the server side people wait a year for parity. i'd always be tempted to buy & overclock fast failing servers. good luck adding HA or a quorum mode to the server. it'd be curious to note how determinstic stackless was, whether multiple instances of the server, handed the same inputs, would produce the same outputs, such that if one cheap super overclocked desktop went down another system in lockstep could take over, was already doing the same computation.

anyways, that's my boring theorycraft. night!

good luck seeing what your november 2010 fleet fights look like, equipped with westmere-ep cores and all your improvements. 800 person dev test is a good start, i'll keep my fingers crossed for your 1000+ person fight with caps & drones. who knows, get any more GHz out of those cores and maybe you wont need the time dialation feature, right? ;)

Hey, you've had StacklessIO already for a while. That was offloading network IO to other cores right? Have these network cores any kind of utilization during Tama type testing or fleet fights?

And what about CarbonIO / BlueNet? Are there tasks other than network IO that you've offloaded out of the GIL lock that are happening in threads other than the main stackless event loop thread? What kind of CPU usages are you seeing out of this, what subsystems have given you the most payoff for offloading?

Gl ccp. Report back.
