Message 11000 - Posted: 16 Feb 2009, 7:53:26 UTC - in response to Message 10999.  

Seems the server can be finicky about updating the application for some reason. I deleted the previous versions (instead of deprecating them), so hopefully it should send them out now.

Can you also delete the old old aplication as well?

Yeah, just cleaned it out of the database ;) Don't really need it there anymore.

Message 11005 - Posted: 16 Feb 2009, 12:49:13 UTC

Funny thing that my AMD X2 @2600 MHz now is faster than a Q6600 @3300 MHZ, 20 minutes compared to 22 minutes with Linux 32-bit, how come?

64-bit Linux is crunching fine here and does them in 18 minutes on a Q6600 @3200 MHz.

Needing around 18.5 minutes on my C2D lappy with v0.19 (64 bit).
Compared to the old standard app it's good (~36-40 minutes with 0.17) but still bad compared to the opti app (~7-8 minutes with opti 0.16). ;-)))
Lovely greetings, Cori

I don't think the windows apps are compiled with any vectorization, so that's probably where you're getting the rest of the benefit from :( I wonder if we could compile the 64 bit windows app with -SSE2 or -SSE3, which probably would bring it pretty close to that.

-SSE2 would guarantee it can still run on all 64-bit systems. -SSE3 excludes at least some early AMD 64-bit systems (I know, because I am running 2 of them!).

But SSE3 is quite a lot faster. ;-)
I don't know how many old 64-bit system are out there though.
If it's not just a very small minority maybe having two 64-bit apps would be a solution?
That would imply of course one has to download one of those apps manually but with a little How-To added it would be easy for most users I guess (installing opti apps is just the same. *grin*)

Yeah, the Linux 64-bit could also have SSE2 optimizations.

The linux 64-bit app does have SSE2. It's using: -O2 -msse2 -ftree-vectorize -funroll-loops

Just added my wife's laptop back to MW and it is using the stock MW 0.19 Win32 app.

First unit took 21:17 and granted 31.56 credits. This is running on a AMD Mobile Sempron 3100+.

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

Switched over my Q9450 @ 3.36GHZ and it ran the first 4 v0.19 WUs in 832 to 837 seconds and still hit the limiter. They were granted from 24.97 to 25.12 credits.

Can't wait to see what this box will do with an opti app (Win32 please) and no limiter.

And my i7 parts come in today. Woo Hoo!!!

You should check with Bernd Machenschalk (Einstein@Home) in regards to doing a wrapper that has CPU feature detection...

Visual Studio does not support auto vectorization (which gives close to 100% gain on Core2/i7 and K10 class CPUs). Therefore, another compiler would definitely help for builds using SSE2.

Per my off-the-cuff analysis here, only 17% of hosts support SSE3. However, I couldn't break this figure out between 32 and 64-bit hosts.

Just swapped from the opti 0.16 client to the new stock 0.19 client, and first 4 away but I couldn't get the accurate figure for time or credit due to insta-purge.

I assume, like Labbie, it is hitting the credit limiter, but the 0.19 is fast compared to the previous stock client (0.17).

On 0.17 my QX9650 took 31 minutes, and I think I saw about 12.5 minutes on 0.19. Yes it is fast, but I was killing WUs in 3.2 minutes with the opti 0.16.

[EDIT]
Just saw another 3 through and report. Got to the results before insta-purge and saw them complete in 741 - 743 seconds and awarded 22.50 CS.

The new v0.18 stock app is also significant faster at PPC Macs to:
Mac mini G4 1,5 GHz are now at 1:15h from 2:15h in the past.
iMac G3 350 MHz now 4:20h vs. 8:15h before - very nice ;)

I was unable to get to check times as I was asleep when it crunched through a few of the 0.18 units and they purged too fast for me to see them when I got up this morning.

There are 2 running at the moment and looks like they will come in around 22 minutes.

All we need now is the Windows apps. <grin>


Have to admit the latest stock windows app. is a significant improvement in time reduction. 45-55 minutes on 2 systems down to 13-15 minutes.

Thanks to those folks who were generous enough to share their code with the project.
