SSE 4.1 and SSE 4.2 (Core 7i) do not add a lot of new instructions, but they likely would help those processors with them. All new processors have the preceding SSE code still there to use so you won't lose that, just whatever small improvements the few extra functions that SSE 4.1 and 4.2 could benefit from. Most of the rest of the code likely uses some SSE 3 and older code that is not superseded by newer instructions.

So my take is it would be nice to get those extra little gains, but the difference may be somewhat minimal. I have no access to a SSE 4.1 chip running both clients in Windows so I can't say for sure. It may provide more of a boost than I think as some instructions are for memory handling and vector computation.

It has been proven that the SEEE3 and SEE4.1 work best on different angles of the work. If we could only set them so the most efficient app crunched each work unit. But that will not happen, so we will just have to use what we have.

Thanks Arkayn. That really helps a lot for my Mac Mini coreduo and iMac 3.06 core2duo. I see you also posted combined versions for Windows as well, including the Win64 version for SSE 4.1. That will work nicely on my core i7.

And linux as well.

Of course I am not running AP on my iMac or the desktop for the moment. Still waiting for that last AP unit to finally clear out of my pending cache. It just went out to the 5th person since the 4th looks like they stopped crunching.

Yeah I noticed that you got linux in there also. The packages worked fine.

The bad thing about SETI is how long it takes to get work units to clear sometimes. I just had a couple from the October clear recently.

I noticed that when my computer started an Astropulse work unit, that the graphics for that task was displayed. Does anyone know if someone is working on an enhanced Astropulse that does not display graphics?

Arkayn, thanks for your efforts with the combined downloads with Alex's version(s).

Crunch3r did the first optimized version for Mac, but he has been having problems with the Linux builds and most likely will not do a Mac version until after he get them done.

Thanks for doing this. On my Core Duo iMac, I am running the 4.28 version of AP. How does this compare to the 5.00? Also in the Readme Folder/ Readme Astropulse, it says "Should run on MacOS 10.4.x and 10.5.x on PowerPC Mac's". Shouldn't that be Intel Macs, or is this not for my computer?

I just copied the readme into the folder so there was installation instructions there, I don't think I read that part. The 4.28 is what Crunch3r based his work on but it validated against the newer stuff.

Now we have to use the 5.00 version as that is all that validates in the system.

Optimized Astropulse 5.00 for Mac OSX (Intel) based computers.

Hi Everyone,

A SETI@Home Astropulse optimized application has been released.

This release offers significantly improved performance for SSE3 capable computers running on Intel-based Mac OSX.

Here are individual links for all the initial release builds:

Intel-Mac OSX Science App:

Mac OSX (Intel) SSE3 Compatible Science App:
Intended for Intel CPUs, running Mac OSX that have SSE3 capability.

Mac OSX (Intel) Astropulse v5.0_SSE3 (Intel-ONLY)

NOTE: The Mac package includes a folder w/ pre-made app_info.xml “combo” files for use w/ multi-beam AK_v8 science applications for Core, Core2 or Core2/Quad-based Xeon processors.

Known issues:
- There is no support for CPUs below SSE3 capability.
- Borderline OC'ers be aware that you may need to back off to maintain stability, the increased throughput of this application will stress all system components more.
- As Always, use these apps AT YOUR OWN RISK.

And most Importantly of all:
Several people have helped make this build possible. First and foremost, Raistmer, Crunch3r & Jason G for leading this effort!!!

Merry Christmas & Happy New Year 2009!!!

Regards,
Gecko

I downloaded and installed the AP client (Thanks Arkayn!). First 2 AP units failed with the same type of error codes. See this link. Anyone else having this issue? I updated to the new version that was published yesterday, but haven't had any new work units yet.

@ Beadman: Which astropulse application are you running? The ported "stock" one provided by Dotsch or the new optimized one released on the 24th?

My first 2 results running Opt AP app on my trusty iMac 2.0Ghz T7200:
http://setiathome.berkeley.edu/resul...tid=1100115454
http://setiathome.berkeley.edu/resul...tid=1100114229

First one validated & granted credit per normal.
2nd WU ran normally & pending results from wingman.

Is anyone else running the new optimized ap having problems?
Again, the optimized version is the one I posted here a few days ago.

If so, please sign-up on forum & open a thread here:
http://lunatics.kwsn.net/index.php

We need to know any issues/problems w/ app crashing, early exits or invalid results.
Keep in mind that the current Cuda issues could pair your valid results against 2 invalid Cuda results & therefore grant you no credit. Watch any "0 credit" results closely to see if you had Cuda wingmen.

Thanks gents

That looks like a stock version as it does not list the other info in there, now that I have seen what an optimized output looks like.

I will enable AP on the Mac for a little bit and see how mine will do.

Downloaded and installed the Dec. 24 version of the AP app. Have completed three WU so far, and all three indicate success, although all three are still pending... MBP C2D 2.4GHz T7700 OS X 10.4.11, BOINC 6.2.18. Each took approximately 84K CPU-sec

Hi all,

I'm wondering if there is any chance to get a client running on iPhone.
Is someone already working on it?
Is there any incompatibility?

I know that the iPhone is really not at all the perfect platform to run such software, but I'm interesting by porting seti@home (or any distributed computing software) on iPhone, so I've a lot of questions before starting this project.

Thanks in advance for your answers.

Best regards,
Alx

Just curious, for those of you running SETI@home on Leopard, how did you guys manage to address the sluggishness on overall OS X performances when all your processing cores are dedicated to Seti...?

I'm stuck with Tiger because of this issue, and Snow Leopard which is supposed to bring in performance enhancements and stability doesn't do good either.

I'm aware of Leopard's lack of "nice"ness issue pertaining process priorities.

I have both Mac Pros Clovertown and Harpertown, both displaying choppy effects on Expose, Dashboard, and Spaces. Spotlight is close to unusable. These happens only with all 8 cores allocated to SETI (or any other BOINC projects). However sluggishness is unnoticeable if they are set to crunch on 7 cores or less.

There is something wrong with your systems, not Seti.

I had Seti running full time on 8 cores for 4 months without any lagging.

If you have any third party extensions or plug-ins, they are more likely to be the cause of the problem.

Nope, I'm not saying SETI has problems.... because I had the same problems with Einstein on both systems as well. What are the chances of both systems of different configurations with a clean-installed Leopard suffering from sluggishness on 8-cores crunching but not 7 or less..? That doesn't happen on Tiger on my Clovertown, though there's no way to have Tiger on a Harpertown-based MP. So it's not a BOINC problem, but more on Leopard itself.

I've seen this too. I set my preferences for SETI to sleep when I'm active, so I don't have a problem while I'm using the machine. It hurts my RAC somewhat when I'm using my machine for a 10-12 hour day, but at least I can then run virtual machines, etc. without everything slowing to a crawl. It does seem to be particular to Leopard, though I didn't really notice it as significant until I started using Parallels on a regular basis.

I installed the new version right when I was already 6 & 5 hours in on some AP units. My time with r84 was right around 28 hours. These 2 units finished at 24.5 and 24 respectively.

I am thinking that it might do around 20 hours on a full run.

r103 lopped off 6 hours on the PC(2.33).

How do you upgrade the optimised AP client without having to screw up the BOINC ownership permission and lose all those downloaded AP WU altogether...?

Every time I perform an upgrade to the optimised clients, I had to reinstall BOINC Manager and lose all unfinished WUs.

You should not lose anything, I never have at all. I have even installed 6.5.0 to test something and then went back to 6.2.18 and my work stayed just fine.

Do you have everything in the default place?

Upgrading/downgrading to different versions of BOINC Manager is fine... It's just the problem of upgrading SETI/AstroPulse clients that's screwing up BOINC ownership which requires a reinstallation of BOINC Manager to restore permission. At this point, all previously unfinished WUs will be lost.

Me too! When I upgraded the AP app a few days ago, I turned off Boinc, did the upgrade, pulled the 6.2.18 Install out of my downloads folder, reinstalled it to fix the permissions, restarted BOINC, and everything worked fine - no loss of WU.

New Subject: The updated AP app is finally running - had to work my cache down... So far it's 5% complete at 92 minutes CPU time which works out to a bit over 30 hours... The December 24 version I tried was coming in at roughly 24 hours per WU...

Finally received an AP WU and finished it.
Here's the results, compared to a selection of the standard SETI WUs, all on a MBP T7700 2.4 GHz 4GB RAM OS X 10.4.11, BOINC 6.2.18:

CPUSEC Credits CPUSec/Credit (lower is better)
72629 749.85 96.9 AP WU
953 14.23 67.0
2711 25.40 106.7
4013 44.84 89.5
4905 53.9 91.0

So, except for those little 14+ credit ones, the new AP optimized is right in the middle of the range. Thanks to all concerned for the increase in performance.

Now that Dotsch has released the AP v5 application I can get PPC machines rolling with the full combined package.

This contains the AK V8 app for Multibeam, the AP 5.0 and the new AP v5 app with a app_info.xml file.

Intel Macs will be coming as soon as the optimized app is released.
