Title: Astro-pulse optimized app?
Post by: autocrosser on 02 Oct 2008, 04:54:07 am: Was wondering if anyone is working on a optimized app for Astro-pulse? Right now on my Core2 Quad running at 3.0--I'm seeing 35/40 hours to finish one unit. Hoping that you guys can pull a rabbit out of the hat again :)

Hope soon will be some initial release for SSE3 and up CPUs.

Post by: Raistmer on 02 Oct 2008, 11:48:22 am: Yes, testing needed, but you need access to prerelease area for that. Ask one of moderators to grant you such access.

Thanks!!!

Linux app is waiting the person who will build it :)
Sources for Windows release are posted along with binaries, hope someone will try to build them under Linux too.

Post by: Raistmer on 11 Oct 2008, 01:39:50 pm: Sorry,but it seems nobody seen him here for pretty long time ...
But sooner or later Linux opt app will be build, no doubts.

Post by: Geek@Play on 12 Oct 2008, 02:24:55 am: 2 AP reported with errors from one of my boxes. This is the message I reported on the Seti site. I don't know how they uploaded and reported with the Seti server down.

Thanks for report. I answered in that thread. In short - it's OCing most probably.

Post by: Urs Echternacht on 20 Oct 2008, 05:17:08 pm: Sadly Crunch3r 's version seems not to work. Here is what stderr.txt looks like on T7200 running OpenSuSe 10.3 64bit after a first standalone test:

Can't open init data file - running in standalone mode

Post by: Urs Echternacht on 21 Oct 2008, 10:18:11 am: Crunch3r did try another build (http://calbe.dw70.de/astrop/AP_linux_32bit_sse3.tar.bz2) today of the optimized AP for linux, this time 32bit sse3. This one seems to work. Testing is underway (early T7200 speedup: ca. 67%)

later: 27.325%, 6:42:00 hous => prediction: ca. 24.52 hours total, taking 60 hours as previous host average, this build seems ca. 2.45 times faster.

the other day: Final run time: 24:14 hours, final speedup factor: 2.47 times faster than stock.

Excellent! Knew it was only a matter of time. Once we have verification of working radar blanking & finalised Berkeley release changes included (if any) I'll drop him a message to get the new updates if he wants them. I've little doubt that whichever compiler he's using on Linux, it's better than MS, so Linux might show a slight advantage for a short while. (Not ready to plunge into an ICC building spree just yet, 'till stock changes settle down anyway. )
