IRC logs of #boinc for Tuesday, 2012-10-16

00:18 *** LarchOye has joined #boinc

00:19 <LarchOye> hey guys, how do I change the working directory / cache path for gridrepublic / boinc?

00:20 <LarchOye> I have an ssd system drive, and I *DO NOT* want to trash it prematurely by having boinc writing to it all the time

00:21 <Tank_Master> boinc only wrights once a min max

00:21 <LarchOye> also: I don't think the ssd is going to do much as far as accelerating the grid projects is concerned....

00:21 <Tank_Master> no, it wont

00:21 <LarchOye> I set mine to write like, 10-20 minutes... BUT

00:21 <LarchOye> Still, I don't want it writing to my SSD...

00:21 <Tank_Master> but, when you install it, you can specify where to place the project files and where to place the data files

00:22 <LarchOye> I have two 7200rpm sata HDD's in this box it can write to all it wants...

00:22 <LarchOye> heh

00:22 <LarchOye> You can?

00:22 <Tank_Master> yes

00:22 <LarchOye> is that a command switch then?

00:22 <Tank_Master> no

00:22 <Tank_Master> well, not that i know of

00:22 <Tank_Master> what OS are you installing it to?

00:23 <LarchOye> win7 x64

00:23 <LarchOye> do I need to install BOINC first, and then GridRepublic?

00:23 <MTughan> The data directory location is stored in the registry. I've changed it after installation without problems, just make sure you move all the data files beforehand.

00:23 <LarchOye> or ProgressThruProc...

00:23 <MTughan> I don't remember the specific key off the top of my head though.

00:23 <LarchOye> hmm, okay MTughan...

00:23 <Tank_Master> i believe grid republic is just a modified version of BOINC

00:23 <MTughan> And shut down BOINC while doing the move.

00:24 <LarchOye> otherwise I was thinking about symlinking it as another possible workaround...

00:24 <LarchOye> is there a 64bit boinc client available yet?

00:24 <Tank_Master> yes

00:24 <LarchOye> (that should be top priority btw)

00:24 <LarchOye> orly

00:24 <MTughan> I think I tried using a directory junction to move the data directory before, I seem to remember that didn't quite work.

00:25 <Tank_Master>

00:25 <Romulus> Title: Download BOINC client software (at

00:25 <LarchOye> you recommend 7.0.28 or .31 ?

00:25 <Tank_Master> doesnt really matter

00:26 <PovAddict> 64-bit client has existed since 2007

00:26 <Tank_Master> im actually on .36

00:26 <LarchOye> do you guys work on the project?

00:26 <PovAddict> LarchOye: I contribute to BOINC on and off

00:26 <LarchOye> PovAddict: yeah I've used it before...  just curious why it's not mainstream yet

00:26 <LarchOye> cool

00:26 <PovAddict> LarchOye: depending on my free time and how much the other developers pissed me off recently

00:27 <Tank_Master> I do not

00:27 <Tank_Master> oh how nice, OINC desides to run a benchmark in the middle of my compiling...

00:27 <LarchOye> yeah I've posted a few threads about ideas for new grid projects- maybe you guys could pass them along to the right people for me...

00:27 <Tank_Master> Boinc*

00:27 <PovAddict> LarchOye: well *that* doesn't work that way :P

00:27 <Tank_Master> no, that doesnt

00:28 <PovAddict> LarchOye: first there's the need to do research or whatever that needs lots of CPU, then comes BOINC as a solution

00:28 <Tank_Master> or GPU

00:28 <PovAddict> it's not like there's bored people wondering what to run on BOINC next

00:29 <LarchOye> okay the boinc client installer let's me change the data dir... cool

00:29 * Tank_Master would still loke to see Boinc mase use of openCL on the intel CPU

00:29 <LarchOye> the prog can install to C:

00:29 <LarchOye> I just don't want the data there... heh

00:29 <LarchOye> hmm okay now to figure out how to connect to gridrepublic account manager...

00:29 <Tank_Master> you can use boincstats as an account manager instead of grid republic

00:30 <Tank_Master> bam has a lot more projects it supports

00:30 <LarchOye> do you recommend it?

00:30 <LarchOye> orly

00:30 <MTughan> I use BAM, like it.

00:30 <Tank_Master> its what i used when i was managering 60 computers at the place i worked at

00:30 <MTughan>

00:30 <Romulus> Title: (at

00:31 <Tank_Master> its far more capible now than back then

00:31 <PovAddict> isn't that last sentence applicable to pretty much anything?

00:31 <MTughan> Not to AOL.

00:31 <MTughan> :P

00:32 <PovAddict> well my internet connection isn't liking the rain so far

00:32 <LarchOye> I've used BAM before... I wonder if my account still exists... heh

00:33 <Tank_Master> most likely

00:33 <LarchOye> woot, it does

00:33 <Tank_Master> hosts auto detech after a period of inactivity, but thats all

00:47 <LarchOye> hrm, I really oughta clean up my projects and stuff...

00:47 <LarchOye> oh btw, the project idea that I have is this:

00:47 <LarchOye> Model the Teraforming of Mars

00:47 <LarchOye> er, simulate... whatever you wanna call it

00:48 <LarchOye> but yeah, basically we should be able to start with the climate prediction project's source code- I think...

00:49 <LarchOye> obviously adjust it for mars...  then add in the ability to run crazy simultations, etc..

00:49 <PovAddict> yeah you have fun with that :P

00:49 <LarchOye> it would be helpful if we had lots and lots of real, current climate data (from as many points on the mars surface / orbit as possible)

00:50 <LarchOye> well- I need some computer scientists, and some climate model scientists to get it rolling...

00:50 <LarchOye> and honestly, it's one of the most important things there is...

00:51 <LarchOye> we literally have all of our eggs in one basket right now...

00:51 <PovAddict> I'd be far more interested in our climate than in mars'

00:52 <LarchOye> the sooner we begin colonizing and teraforming mars, etc...  the better chance the human race has of longevity...

00:53 <LarchOye> I'm far more interested in manned mars projects right now, than earth climate blah blah....

00:53 <PovAddict> if we keep wasting oil in our 10%-efficiency cars and in generating electricity, we won't have enough for rocket fuel to send enough people to mars

00:54 <LarchOye> honestly, the whole "global warming" debate is ridiculous.  for 10+ years people have been arguing yes/no blah blah... Yet NONE of them have bought any freakin solar panels yet

00:54 <LarchOye> omfg, oil is so obnoxious I don't know where to start...

00:54 <PovAddict> we *will* run out of it

00:54 <LarchOye> I'm really interested in solar thermal right now actually...

00:54 <LarchOye> well yeah, no shit ;_

00:54 <wdsmia> asks LarchOye to please watch his or her language… Thanks, your friendly channel op.

00:54 <LarchOye> ;)

00:54 <LarchOye> and a lot sooner than you think...

00:54 <LarchOye> bleh, sry

00:55 <PovAddict> and there's no alternative to it for rocket fuel

00:55 <PovAddict> or airplanes, for that matter

00:55 <LarchOye> grrr I hate not being able to swear anywhere on freenode...

00:55 <LarchOye> rocket fuel is h2 + o2

00:55 <LarchOye> sure as shucks aint gasoline

00:55 <PovAddict> hm true that :p

00:56 <LarchOye> h2 + o2 is the best weight / thrust option there is

00:56 <LarchOye> unless you could somehow get h2 plus he or li or something to work, heh

00:57 <PovAddict> the holy grail would be to find a way to collect energy during re-entry

00:59 <LarchOye> hmm

00:59 <LarchOye> that's a great idea

01:00 <PovAddict> you need a lot of energy to get a rocket to fly up and leave the atmosphere

01:00 <PovAddict> and you "get" a lot of energy during reentry, but it's in the form of heat that we try hard to dissipate

01:02 <LarchOye> nah man

01:02 <LarchOye> check this...

01:02 <LarchOye> are you familiar with Solar Thermal units?

01:03 <LarchOye> the ones that use a reflective parabolic surface that focuses the sun's rays onto a pipe containing some kind of heat transfer liquid..?

01:03 <PovAddict> yeah

01:04 <PovAddict> you can reach insane temperatures with that

01:04 <LarchOye> er- if you're familiar with the concept of heat pipes for cooling in computers, etc... that's pretty much what I'm getting at

01:04 <LarchOye> F@CK YEAH

01:04 <LarchOye> 700+°F I hear is the NORM temp those systems run at...??

01:05 <PovAddict> I saw a fancy system on TV

01:05 <PovAddict> they had those mirrors in a very large area of a desert

01:05 <LarchOye> so basically all we need to do is design some creative methods for turning the otherwise wasted heat from re-entry into something useful...

01:06 <PovAddict> and heated a special fluid in pipes

01:06 <PovAddict> the nice property of that fluid is that it conserved heat for a very long time

01:06 <PovAddict> so the liquid kept circulating overnight

01:06 <LarchOye> yeah the focused mirror arrays are sorta neat- except the whole "Grid" concept/design for providing electricity is the absolute WRONG way to do engineering...

01:07 <PovAddict> the sun came back up before the thing cooled enough to stop generating electricity

01:07 <LarchOye> I'm much more interested in small scale, local power generation- with grid tie

01:07 <LarchOye> haha, nice

01:07 <LarchOye> yeah that liquid would probably circulate for days or even weeks before it completely lost it's thermal capacity....

01:08 <PovAddict> it was tricky to tune, because if it cooled enough the fluid would go solid, which would cause a serious mess

01:09 <LarchOye> yeah I'm trying to come up with plans to implement ~1MWatt wind turbines on public school campuses, along with solar thermal collectors on the roofs of the buildings...  and supply the surrounding neighborhoods with electricity, and possibly even an alternative to natural gas for heating...

01:09 <LarchOye> orly, solid huh... any idea what the fluid was that they were using?

01:10 <PovAddict> some kind of salt

01:10 <LarchOye> hmm okay

01:10 <LarchOye> yeah I think it might make sense to have multiple stages of heat transfer or something....

01:10 <PovAddict> "Solar energy can be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 TJ in its 68 m3 storage tank"

01:11 <LarchOye> like, the primary fluid transfers heat to a steam generating system, and some alcohol/amonia/whatever type systems as well-

01:11 *** FnorZ has joined #boinc

01:11 <PovAddict> my small mind can't grasp the scale of 1.44TJ

01:11 <LarchOye> 68 m3?

01:11 <PovAddict> 68 m³

01:11 <PovAddict> cubic meters

01:11 <LarchOye> oh m^3

01:12 <PovAddict> yeah, that often gets messed up when copying as text :P

01:12 <LarchOye> TI89 syntax is the way to go for irc convo btw ;)

01:12 <LarchOye> ahhh gotcha

01:12 <LarchOye> bbiab- i need a smoke / food or something..

01:13 <PovAddict> copying from a webpage with m<sup>3</sup> HTML gives m3

01:13 <PovAddict> I don't know of any browser that does differently

01:26 *** FnorZ has quit IRC

01:32 <LarchOye> bbiab, gonna plug my puter into this ups...  apparently you have to power everything off to do that, heh
