IRC logs of #boinc for Sunday, 2009-08-09

00:02 <efc> Whats close to knapsack?

00:04 <PovAddict> efc: lots of WUs, with different RAM usage, and a limit of how much RAM you can use

00:05 <PovAddict> start as many WUs as possible, but don't fill RAM, and don't leave tasks forever "waiting for memory"

00:05 <efc> Wonder why people like throwing NP complete problems at BOINC

00:05 <PovAddict> maybe it's even a good idea to keep an interesting mix of high-RAM and low-RAM tasks, for performance (high RAM tasks are likely to also have high CPU cache misses, and two programs constantly filling the cache throw performance down)

00:22 <zombie_67> what is the server version of i7?

00:23 <MTughan> Xeon.

00:23 <zombie_67> xeon means many codenames

00:23 <MTughan> All Intel's server CPUs go under the name Xeon.

00:23 <MTughan> Look for Nehalem based Xeons then.

00:24 <zombie_67> ah, nehalem

00:24 <MTughan> i7 is Nehalem too.

00:25 <zombie_67> gainstown

00:25 <MTughan> Intel will be releasing new versions of the CPUs at 32nm soon though. Apparently, 6-core and higher clocked for the same power envelope as the current i7s.

00:26 <zombie_67> e/x 55xx

00:26 <MTughan> Hmm... I don't see hex-core procs on Wikipedia, but I though I remembered reading about them.

00:27 <zombie_67> they exist

00:27 <MTughan> And yes, you'll be looking at Bloomfield or Gainestown.

00:27 <zombie_67> I know this for sure....

00:27 <MTughan> Yeah, they exist, but as Dunnington, which is Core 2 based.

00:27 <zombie_67> Gulftown

00:27 <zombie_67> ?

00:27 <MTughan> Oh, I'm looking at the wrong table...

00:28 <zombie_67> Westmere

00:28 <MTughan> Yes, Gulftown is it. Hex-core, Core i9.

00:28 <zombie_67> 6 seems an odd number

00:28 <MTughan>

00:29 <Romulus> <> (at

00:29 <MTughan> It is... Maybe 8-core with two disabled for better yields?

00:31 <zombie_67> if so, then where are the 8-core processsors?

00:31 <MTughan> Hmm, good point.

00:32 <zombie_67> I am thinking it has to do with fitting cores in a fixed space

00:32 <BSDeepa> There's octocore?

00:32 <zombie_67> there is not

00:33 <BSDeepa> bah

00:33 <MTughan> I think Nehalem was designed to be more modular, so perhaps Intel is capitalizing on that.

00:34 <MTughan> Adding more cores to the same die space with the die shrink.

00:35 <zombie_67> exactly

00:37 <MTughan> Yep. Part of the Technogy section on Wikipedia: "Modular blocks of components such as cores that can be added and subtracted for varying market segments"

00:44 <zombie_67>

00:44 <Romulus> <> (at

00:44 <zombie_67> s-core servers

00:44 <zombie_67> 6 core

00:46 <MTughan> Yeah, that's Dunnington.

00:46 <MTughan> Same processor as the Core 2 series.

00:47 <zombie_67> oh

00:48 <MTughan>

00:49 <Romulus> <> (at

00:49 <MTughan> BTW, these are the Nehalem based Xeons you're probably looking for:

00:49 <Romulus> <> (at

00:50 <zombie_67> yeah

00:51 <zombie_67> [21:26]  <zombie_67> e/x 55xx

00:51 <MTughan> And looks like W too.

00:52 <zombie_67> what does W mean?

00:52 <MTughan> Workstation maybe? Looks like the high-end.

00:53 <zombie_67> more expensive than X

00:53 <zombie_67> more power too

00:54 <zombie_67> brb

00:57 <zombie_67> back

00:57 <zombie_67> as cool as nehalem is

00:58 <zombie_67> max cores/threads is not the way to go for max credits

00:58 <MTughan> What is?

00:58 <zombie_67> a super cheap CPU, and lots of CPUs is

00:58 <MTughan> Which is max cores, just not on one die.

00:59 <zombie_67> but not max CPU cores

00:59 <BSDeepa> You could just go out and ask companies if they got any computers they're gonna throw away

00:59 <zombie_67> the cost of the HW is not the (real) problem

00:59 <MTughan> Also, having more CPUs requires more supporting parts as well, and that can possible throw off costs.

01:00 <efc> The Netbook was getting pretty good WU/watt, while I was running it

01:02 <efc>

01:02 <Romulus> <> (at

01:02 <zombie_67> the dual core w/ HT ATOM will make some massive credits/watt with AWUA

01:02 <efc> 18 watts

01:02 <zombie_67> AQUA

01:02 <efc> the desktop atoms use more power though due to the crippled chipsets

01:03 <zombie_67> never heard of a crippled chipset

01:03 <efc> power wise

01:03 <MTughan> I thought all Atoms used the same chipset?

01:03 <efc> 945G and 945GC

01:03 <efc> the netbooks use lower power ones

01:03 <efc> 945GSE

01:03 <zombie_67> how does one cripple a chip-set powerwise?

01:04 <efc> the 945G uses 22 watts or something like that

01:04 <efc> for a 4 watt CPU

01:04 <zombie_67> okay, so the gse is BETTER, not that the others are crippled

01:04 <efc> GSE is something like 10 or 12

01:05 *** infinisoft has quit IRC

01:05 <efc> I call it crippling when the marketing department decides to withhold a better product thats already available

01:05 <zombie_67> still, the best credits = ATOM with 4x GPUs

01:06 <zombie_67> no, crippling = allowing you to use only (say) 10 of 8 cores in a CPU.

01:06 <zombie_67> reverse that

01:13 <PovAddict> it's crippling if those other two cores actually work

02:12 <Tank_Master> hiya Nickuwo

02:13 <Nickuwo> hey Tank

02:13 <Tank_Master> sup?

02:13 <Nickuwo> not much... watching a math lecture... I don't understand it :(

02:13 <Tank_Master> lol

02:13 <Nickuwo> u?

02:14 <Tank_Master> rather be working on your project?

02:14 <Tank_Master> just got back from doing the sound for a gig at church

02:15 *** jasong has quit IRC

02:15 <Nickuwo> hehe, I'm not sure. the papers I'm looking at are just about as math intensive. Doing sound?! thats awesome!

02:15 <Nickuwo> do you play an instruments?

02:15 <Tank_Master> used to

02:16 <Tank_Master> but I cant read sheet anymore

02:16 <Nickuwo> bah, you dont need to read to play

02:16 <Tank_Master> I just manage the mics and sound board

02:16 <Tank_Master> the support stuff for the stage, while I lerk in the background :D

02:17 <Tank_Master> plus sides are I get in free and I get to make th sound the way *I* want it to :P

02:17 <Nickuwo> thats pretty cool. I love that stuff... I just jammed with a few ppl today and recorded it. I should probably be mixing it along with a few other things...

02:18 <Tank_Master> I recorded onto casset tape :P

02:18 <Tank_Master> we so need to get a cd recorder at church

02:19 <Nickuwo> heh. cassett works :). what did you play?

02:20 <Tank_Master> back in elem school I played the violin

02:20 *** quail_linux has joined #boinc

02:20 <Nickuwo> nice

02:20 *** quail has quit IRC

02:20 *** quail_linux is now known as quail

02:20 <Tank_Master> was third for my grade one of the years

02:20 <Nickuwo> thats an interesting instrument... difficult I hear

02:21 <Tank_Master> wasnt for me

02:21 <Tank_Master> but I got a good ear

02:21 <Nickuwo> why didnt you stick with it?

02:21 <Tank_Master> I could play songs that someone else played with a differnt insterment

02:21 <Tank_Master> lost interest

02:21 <Tank_Master> took up to much time

02:21 <Nickuwo> bummer

02:22 <Tank_Master> didnt help they moved the practus time to the time that resess was at

02:22 <Nickuwo> eh, recess is a priority

02:23 <Tank_Master> at that age? heck yeah :P

02:25 <Tank_Master> though I have been helping with the sound system at church since I was in the 6th grade

02:25 <Tank_Master> so I know my way around the board quite well

02:26 <Nickuwo> thats cool. you should go into sound engineering. and mix some shit for me :)O

02:26 <wdsmia> asks Nickuwo to please watch his or her language Thanks, your friendly channel op.

02:26 <Tank_Master> lol

02:53 <zombie67> bout time

02:53 <Tank_Master> ?

02:53 <zombie67> heh

02:54 <zombie67> rsef was sweating all the work you had him manage

02:54 *** jasongopher has quit IRC

02:54 <Tank_Master> wasnt much

02:54 <zombie67> hah

02:54 <Tank_Master> build up hideouts mostly

02:54 <zombie67> hideouts?

02:55 <Tank_Master> on test

02:55 <zombie67> oh

02:55 <zombie67> he said he had to manage several worlds at once

02:55 <Tank_Master> ill be gone again this weekend for about 2 weeks

02:55 <zombie67> what?!

02:55 <zombie67> wow!

02:56 <zombie67> where are you going?

02:56 <zombie67> nice life

02:56 <Tank_Master> going to glasher NP

02:56 <zombie67> NP?

02:56 <Tank_Master> national park

02:56 <zombie67> ah

02:56 <zombie67> THIS TIME transfer gerneral and diplo

02:56 <Tank_Master> on theta?

02:57 <Tank_Master> only b2 can do that

02:57 <zombie67> yeah

02:57 <zombie67> so tell him

02:57 <Tank_Master> he's the leader

02:57 <zombie67> now

02:57 <Tank_Master> he is in vacation mode

02:57 <zombie67> WTF???

02:57 <Tank_Master> has been for a while

02:57 <zombie67> how do they allow a leader to do that??

02:57 <Tank_Master> same why u or i go into vacation mode

02:58 <zombie67> no

02:58 <Tank_Master> oh, assign roles?

02:58 <Tank_Master> its an option in the embassy

02:58 <zombie67> if you own a reposibility role, that should not be possible

02:58 <Tank_Master> ahh, ic, yeah

02:58 <Tank_Master> but allas, they do

02:58 <zombie67> k

02:59 <zombie67> last resort, let's do the same as last time

02:59 <Tank_Master> I may be able to get a go to transfer it, but im not sure

22:15 <PovAddict> they fixed the issue with international characters, so I joined the PTP app to try it out

22:15 <PovAddict> I'm writing a message explaining how much my experience sucked

23:46 *** Eythan has quit IRC

23:56 <PovAddict> so those ink-thirsty money-wasting machines called "printers" ever work right?

23:56 <PovAddict> I think manufacturers have lost their mind

23:57 <Tank_Master> all they care about is selling you crap

23:57 <PovAddict> eg. Google's income is advertising, but they constantly improve all their other services, most of which are free

23:57 <PovAddict> EPSON's income is selling ink, and it's clear the printer drivers are designed to do one thing well: let you know when you're out of ink and have a handy "buy ink" button

23:58 <efc> There are some more expensive printers with cheaper ink.. and I doubt they sell much.

23:58 <PovAddict> efc: EPSON has cheaper ink than HP

23:58 <PovAddict> HP cartridges have the whole ink-drop-firing mechanism

23:59 <efc> Can't remember who I'm thinking of.. they also had separate color tanks so you didn't have to chunk the cart for one color being out

23:59 <PovAddict> EPSON ink cartridges aren't much more than little plastic tanks, and all the mechanisms are in the printer

23:59 <PovAddict> well, almost every manufacturer has separate colors by now

23:59 <PovAddict> here's a stupidity, clearly designed to make you buy ink:
