Milkyway@home - September update

ToxicTBag · 27 Oct 2010 at 21:22

Evening Mr Edge, its down to 6m30s on average now am running 2 tasks per gpu 4850 but its 82 degrees with the fan at 100 percent, am looking around and in 2 minds wether to get a better ati card or wait until next month and see what suprises nvidia has in store..... why oh why does nothing these days seem to go smoothly...grumble moan whinge gripe

**Edit** To heck with that 82 blinking degrees...

CGS · 27 Oct 2010 at 21:30

Dont know if any of you already know this, but crunch3r has brought out optimised type file thingys for the GTX4xxx series of nvidia cards for MW

you can find em on this link
http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=1987

ive been running em for a day or so on my GTX460 and works fine though around 700secs per wu much slower than ati hd4750, but while seti is down I thought why not

Also it works running two wu's on one card
Has anyone else tried it ?

ToxicTBag · 27 Oct 2010 at 21:44

CGS your a gent and a scholar.....and have narrowly saved me from pulling out my last grey hair. Thank you very very much for that.....muhahhhaaaaaaa

Will try it in next half hour and post back if anything unusual.....muchas grasias

CGS · 27 Oct 2010 at 21:46

your welcome

I wouldn't worry to much all 3 of my 295's have been running between 80 and 87 Deg for months now

ToxicTBag · 27 Oct 2010 at 22:12

Oh this app is nice allowing .2 for cpu and .5 gpu it does a milyway wu in 5 mins 35 sec, c 725 fan 75 gtx470

Yup Mr Reaver sah the room is warming as we speak.....roll on midnight and break out the hawaian shorts lol

1cpu and 1 gpu only shaves off about 20 secs 5m5s so back to first try, there's going to be a big jump in milkyway output if people start using this app hurrah!!

Harlequin · 27 Oct 2010 at 23:46

since seti is dwon followed the chat to here - so how do i get my gtx 460 doing anything? right now its sitting idle

ToxicTBag · 28 Oct 2010 at 01:14

Hi Harlequin take a look a few posts up to CGS post follow the link and download the mw optimised app. If your not allready doing milkyway attach to project mway then copy the files you just downloaded into your milkywa folder inside your boinc data folder.
Restart boinc and voila

Harlequin · 28 Oct 2010 at 07:38

doh serves me right for posting late at night - its only using the gfx card now? sorry feeling like a noob...

ReaVerUK · 28 Oct 2010 at 11:40

You'll need to edit the app_info.xml to include the cpu tasks as well. The one you installed from the above link only has reference to GPU tasks.

I'm not that hot with MW@H app_info's but you'll need to add something along the lines of the following depending on the actual app you use for CPU.

Code:

<app_info>
 <app>
  <name>milkyway</name>
 </app>
 <file_info>
  <name>astronomy_0.21_x64_SSE3.exe</name>
  <executable/>
 </file_info>

 <app_version>
  <app_name>milkyway</app_name>
  <version_num>21</version_num>
  <file_ref>
   <file_name>astronomy_0.21_x64_SSE3.exe</file_name>
   <main_program/>
  </file_ref>
 </app_version>

 <app_version>
  <app_name>milkyway</app_name>
  <version_num>20</version_num>
  <file_ref>
   <file_name>astronomy_0.21_x64_SSE3.exe</file_name>
   <main_program/>
  </file_ref>
 </app_version>
</app_info>

This is mine for CPU only using to .21 app. You may want to process all of the current WU's whilst set to 'no new tasks' before playing just to make sure you don't mess anything up by mistake.

OK Harlequin i've been playing and have got mine running 2 WU's per GTX460 and using the CPU as well.

If you need the .21 app it can be found here http://milkyway.cs.rpi.edu/milkyway/download/

can you help, I cant find the .21 app in there just to many.
using i7 win7 32bit so what one should i select ?
grateful for any help

Hi, There doesn't seem to be a 32bit 0.21 app listed :confused:

and the site i originally used (arkayn) doesn't support them anymore

If only you needed the 64bit then i could have sent you it. Unless anyone around here happens to have it and could send it your way.
The file should work with the stock app (0.40?) if you replace any reference to 'astronomy_0.21_x64_SSE3.exe' with the appropriate file name.

What .exe's have you got in your MW project folder?

ToxicTBag · 30 Oct 2010 at 15:14

Afraid i dont have it either, just running mway on gpu

kolala · 30 Oct 2010 at 15:39

I have a copy of the 32 bit SSE3 ver0.21 that was previously available and anyone is welcome to a copy (mail me kolala at sky dot com ) but there may be a reason for its withdrawal eg it might not work with n-body data files or whatever...so use with caution.

Another option could be to revert to stock to get the non-optimized 32 bit app downloaded (easy), then create an appinfo file to use both non optimized CPU app and optimized GPU apps (hard)

I'm gonna give it a go later on when i've cleared my cache (~8Hrs) at least that way we will know one way or the other.

As you may be able to tell i'm v.bored 2 weeks off work is too much (unless your actually @ work waiting for it

)

CGS · 30 Oct 2010 at 16:24

let me know how you get on dont think i have any exe's other than cuda one for gtx460
