14:15 <PovAddict> I have no idea how long einstein tasks take, so I don't see the weirdness there :P

14:17 <efc> they are fairly slow for me, about a day a piece

14:53 * efc looks at the recent client list for seti@home

14:53 <efc> hppa2.0w-hp-hpux11.11  ..  i386-pc-os2-emx

14:55 <efc> wow, there is really supposed to be an OS/2 version.

14:56 <magnetik_> is there any way to check if GPU is working with BOINC ?

15:03 <efc> it may say on the application name, but not sure

15:03 <efc> my (new) GPU is still way too old

15:03 <magnetik_> i've a GTX 560 Ti, latest Nvidia driver, but I think it's unused

15:04 <PovAddict> touch the GPU

15:04 <PovAddict> if you burn your finger, it's working

15:04 <magnetik_> it's not.. any way to enable it ? :/

15:20 *** Caterpillar has joined #boinc

15:29 *** denom has joined #boinc

15:30 <denom> hey do boinc devs hang out here?

15:31 <denom> I wondering how I can get more precise statistics from the various boinc projects

15:31 <denom> s/I/I'm/

15:33 <denom> I'm looking for stats on how people use there computers, for instance: the distribution of when people leave there computers on...

15:33 <denom> wow, bad day for spelling :)

15:33 <denom> of course I meant `their`

15:34 <PovAddict> that information isn't public

15:35 <PovAddict> the statistics file has information for every single host, adding "fraction of the day the computer is on" to that list would have privacy implications

15:35 <PovAddict> I guess you could contact admins of projects asking for the aggregate data you need

15:44 <denom> PovAddict, I didn't think about privacy issues :/  The problem I have with the current metrics is that the efficacy of the hosts are measured in the "smooth" way that doesn't reveal the granularity of the usage

15:45 <denom> I think I could get around that by aggregating by cpu/computer-type (dropping the references to particular individuals)

15:45 <PovAddict> well

15:46 <PovAddict> even with DB access, the only information you can know is a rolling average of "percentage of time user is active / computer is on / BOINC is processing"

15:46 <denom> Unless a particular project timestamps each unit of work completed?

15:47 <PovAddict> specific information of eg. what hours of the day the computer is on (morning? evening?) isn't even measured by the client, let alone uploaded

15:47 <PovAddict> you could have very rough information based on when it contacts the server (if there's a time range where it never connects, it might be off, or network-less)

15:48 <denom> I think for my purposes I just need a timeseries of when the user is contributing through the day..

15:48 <denom> so info about computer on/off may not be needed

15:49 <denom> If we know the cpu class, how much cpu time, when the work chunk is completed, that would be enough to get a distribution

15:49 <denom> of *roughly* when the machine is active..

15:50 <denom> My purpose is to cluster users into categories: `servers`, `desktops`, `laptops`

15:50 <PovAddict> hmm

15:51 <PovAddict> not sure if anything stores when tasks are completed

15:53 <denom> I've  looked at e.g. the boinc SETI stats, and the metric that gauges how much a user is contributing (can't think of what it's called right now) has a temporal dimension.  It's just exponentially smoothed over a week (prpbably for privacy?)

15:54 <denom> I may just contact a project and ask what they think

15:54 <denom> It's good to talk about the prblem though, it becomes clearer :)

15:55 <PovAddict> recent average credit?

15:55 <PovAddict> that's calculated by all projects, server-side

15:55 <PovAddict> it uses some mathematical function for exponential decay

15:57 <PovAddict> denom: http://boinc.berkeley.edu/trac/browser/trunk/boinc/lib/util.cpp#L227

15:59 <denom> thanks PovAddict, this is helpful. I'll have to trace this code a bit

17:15 <junaidnaseer> hi ... there ... i just started using boinc on my computer ... i have a problem though ... the boinc is creating files in my home directory ... all over the place instead of creating a boinc directory and putting everything in it ... any work arounds ? please ? thank you ...

17:16 <PovAddict> boinc creates files in whatever directory you started it

17:16 <PovAddict> you shouldn't have started it from your home directory

17:16 <junaidnaseer> oooh

17:16 <junaidnaseer> ok

17:16 <junaidnaseer> thanks for the info

17:16 <junaidnaseer> :)

17:16 <PovAddict> you'll also have problems getting work since boinc will think it's using too much of your disk space

17:17 <PovAddict> because it thinks the entire home directory contains boinc files

17:25 <junaidnaseer> PovAddict, hmmm ... ok ... thanks a lot for the prompt reply ... I moved everything to a .boinc directory ... and started the client again ...

17:29 <junaidnaseer> PovAddict, I don't know, maybe I did something wrong, BUT I notice one thing NOW ... one is that I keep getting an error "Error: Cannot get the official hostname (error 0: Succeeded)" ? ... although everything seems to work fine and I can connect to all my 3 projects ... :)
