I just looked at the code and i see the problem. The stock app should be updated by the end of the day.


Nice :) But don't forget to test it across all platforms, since i'm not that sure that all OS will give the same output. At least that's what i've seen a while ago.

At least my SSE3-App I linked to in this thread does not suffer from any of these shortcomings ;)

I for one am grateful for you making this available Cluster Physik.

I've already added it to www.arizmoon.com which I will be updating now with what I think are the 'correct' SSE2 and SSE apps.

OK, I've updated www.arizmoon.com with what has been agreed in this thread as usable optimized apps for SSE, SSE2 and SSE3.

Please let me know if I'm wrong, thanks.

I have moved my additional download resource to www.zslip.com

A reminder on how to use CPU-Z;

On www.zslip.com you will find a link to CPU-Z. Download that and run CPU-Z on your PC.

Under the CPU tab in CPU-Z the 'Instructions' may show SSE, SSE2, SSSE3...

If all are included you can use SSE3, but if only SSE and SSE2 then only use SSE2. Use SSE if the other 2 do not appear.

Shut down your BOINC manager. Copy the appropriate app_info.xml and astronomy....exe app file as appropriate
to your 'projects' file milkyway.cs.rpi.edu_milkyway.

Restart BOINC.

In your BOINC Manager, under the 'Messages' tab, check that "Found app_info.xml; using anonymous platform"
appears in the first few lines. This confirms that BOINC is using the optimized app.

Just to be sure I have this right since I have been away for a few weeks.

The SSE2 application currently on zslip is different from the one that had been available at arizmoon a couple of days ago. Different hashes and the current zslip one I find to be approximately 25% slower.

Results from both have given validated results for me. So, is the current zslip application the one that gives more reliable results compared to the stock application?

You can try the SSE MW_SSEV2.zip app.It should be 25% faster than the SSE2 astronomy_sse2_app.

Original app:
fitness: -3.046272445362277

SSEV2:
fitness: -3.046272445362275

@ICE
You can delete the SSE2 astronomy_sse2_app.rar.It is the same,but slower.

You are welcome.

I have found a faster SSE2 app.It is about 20% faster than the SSE2_V2 app.

MW_SSE2_V3

Original app:
fitness: -3.046272445362277

MW_SSE2_V3:
fitness: -3.046272445362275

zslip is updated.

Hi Ice.
Only a little hint:
You should mention on the site that these are only Windows apps.
Someone could mistaken them for Linux ones. ;-)
The most who come there will know it from here, but just to make it sure. ;-)

Just installed the sse3 app and runs really fast.
7 minutes for each task instead of 45 on phenom 9500.

But why is credit for each task ~13 points instead of ~40 that it was?
Shouldn't it be the same?

Also, on my second computer, a xeon 5410 2.33mhz quad, the credit for each unit
is 9.2 points, Which results in the same 10500 credit per day as the phenom 9500!!!

What's up?

The admins have set a credits limit of 108 credits per core/hour. If your machine is faster you can do a lot of wus only obtaining 108cr/h.

More work but the same credits... Absourd...

That's really absurd.

I wonder what their reasoning is.

Why would a 35000 credit/day machine only get 10500.
