I have a question:
astronomy_0.19_SSSE3.exe I use and I wonder if the version astronomy_0.20SSE3.exe calculate more quickly ...
Thank you very much in advance for your response and your help.

I don't think there was much difference. Mainly that it gives more data while viewing the wus.

Version 0.20b may be a bit (5% or so) faster.

Thank you very much, but I repeat my question with fewer errors ..

My computer courses on the CPU: astronomy_0.19_SSSE3.exe (win_0.19_SSSE3) and I wonder if the version astronomy_0.20_SSE3.exe (win_0.20_Win32_SSE3) calculate more quickly.

There is no version optimized for my GPU: Intel (R) Graphics Media Accelerator 3100 P35/G33/G31 Express Chipset
driver: igxprd32.dll version 6.14.10.5029
Clok GPU: 400MHz

Following your reply I do not know if it is good to do with 0.20b .....

Thank you very much in advance for your answers ...

The application you are running is an optimized CPU application. It will not make use of your GPU (but to be honest, there's not much to make use -of-, considering we're talking integrated graphics), nor will any of the applications available for Milkyway@Home, including the official ones. You should upgrade to 0.20 for the small speed boost, but that's the best you can do unless you get yourself a good dedicated graphics card (one of the higher end ATI ones is currently recommended for this project).

I would agree and concur with that.

Check the highlights. You are describing two different opt apps. One uses SSSE3 instructions, while the other only uses SSE3 instructions. If what you have typed is correct then the SSSE3 app is probably faster then the SSE3 app (regardless of the fact that the SSE3 is revision 0.20 and the SSSE3 is revision 0.19). At least this is the experience I have.

As for GPU, opt. apps are for selected Nvidia and ATI cards. You are using an inbuilt graphics system (as displayed by the line: Intel (R) Graphics Media Accelerator).

Hope this helps.

Never surrender and never give up. In the darkest hour there is always hope.

Message 37515 - Posted: 18 Mar 2010, 19:24:34 UTC - in response to Message 37510.  

perhaps checking "messages" possible your card doesn't support double pressision,
or that you have the CPU project running instead of the ati13ati13 GPU projects,

go to preferences and select only GPU projects, next time, you get new jobs you get the gpu then.

faudra controller les messages, car possible que la carte ne supporte pas double presission calculations
possible aussi que tu a un job qui tourne sur CPU de milkyway, alors faudra y allez sur les preferences et cochez que les GPU calculations. la prochaine fois il ne prendre plus les CPU alors.


regards

Hi, my XP64 host (QX9650&9800GTX+&GTS250), runs 6 WU's, at a time, cause the SETI WU's only use 4% (0.04) of the CPU. (4x CPDN + 0.04CPU+GPU + 0.04CPU+GPU)

The difference with Collatz C.* is even bigger and Milky Way, could 'act' the same.
Depends if the WU can be run on the GPU completely, but does has to be loaded by the CPU.

Btw. I should try a SSSE3 CPU app. Is there a DownLoad Site?
Trying a HD5770 at Collatz C., it's [i]single precision, so can't use it here, unfortunatly.

Message 37719 - Posted: 24 Mar 2010, 13:42:45 UTC - in response to Message 37702.  

Did found the optimized app.'s tried the X64 SSE3 app., which is faster, compaired to stock.

Also found a SSSE3, x86 version, I'm trying this ATM.
Only had a few MW WU's, cause I didn't know if the SSSE3 x86 app., is compatible with XP x64 OS and BOINC 6.10.17 X64![/color]

I do understand, from what I've read in the forum pages, only a Double Precision GPU, can be used for (optimized) GPU-Crunching.

Optimized or stock, MW only uses a double precision GPU.
