You will need to add some lines to the app_info.xml file.

They plan on releasing one here in a couple of days.

I´ve read that a WU Astropulse will take about a weak. What kind of CPU is this calculated on and is it a 24/7 running computer. With only 14 days return it takes most cruncers out.

I´m running an AMD XP 4800+ @ 2,5 GHZ.
Most astropulse units was running 4 - 5 days at beta.

On my old Opteron-242 running at 1.6 GHz, it seems will clock-in on 6.3 days cpu-time, while on C2D-4400 running at 2 GHz it takes around 55 hours cpu-time.

So, any Core2-duo or Core2-quad crunching atleast 25% of the time can run Astropulse, while a 1.6 GHz Opteron/Amd64 must crunch atleast 60% of the time.

The faster the computer, the less time it needs to crunch to meet the deadline...

You can crunch all of the Astrokitty some of the time, and some of the Astrokitty all of the time, but you just can't crunch all of the Astrokitty all of the time....LOL.

With your Q9300 running at 3.525 GHz, would guess you'll use around 30 hours to finish Astropulse-wu's...

Hmm, it would be interesting to see, if anyone manages to use less than 24 hours on Astropulse-wu's, or if not, how long before it's possible...

So, a X9650 @ 3400MHz., should do them in 15-18 hours....With a SSE4.1 or SSSE3 enhenced.
You also run an opti app., like the AK_V8_SSxE3/4.1 opti versions.

No there isn´t an optimized app for astropulse yet.
You have to run the official.

How to get work for Astropulse when using optimized SETI@home application?

Henri.


I don't have one handy offhand, but the procedure and tips for setting up the app_info file was covered over on Beta back we were running Joe's experimental MB app's for 9x and AP at the same time (around 12/06-1/07, IIRC).

You could probably use that one as a start and just make sure all the filenames and version numbers are updated to reflect what we have here on the main project, if you're looking to get a head start.

AFAIK......optimized does not work on Astrokitty.......

Uhh.. big news..!! :-)

How it will be?

I crunch 100 % SETI@home..
When and where I can get the new app_info.xml ?(I'm an opt. app user :-)
So how much % SETI@home Enhanced and how much % Astropulse WUs I will get?
How are the credits? It's the same like with SETI@home Enhanced?
When we will see opt. Astropulse apps?

Which kind of WUs are Astropulse WUs? What will be crunched there?

Questions and questions.. ;-D

It will be interisting to see how things sort out betwix Apple and PC flavors of AMD/Intel [Windows,Linux etc].
When we finally figure it all out, all the rules will change and we can start all over again.

Questions and questions.. ;-D

A few partial answers:

A. In the SETI Beta "AstroPulse release soon" thread, this post by Richard Haselgrove includes both the URLs for downloading the AstroPulse files and the additions which need to be made to app_info.xml for Windows. Read a little further in the thread to see that it would be best to also remove the spaces in:

<executable />

<main_program />

Nearby posts in the same thread by Urs Echternacht give the patterns for Linux.

B. If the same data is split with an mb_splitter and an ap_splitter, there will be 40.4 times as many MB workunits as AP workunits. I'd expect that to be the eventual normal mode, though for now they're limiting AP work. However, the splitters work at different rates and MB splitting is inherently bursty while AP isn't. That means the work is not going to be evenly distributed in the project "Ready to send" pool and even the fastest hosts are likely to have periods when the host queue doesn't have a mix.

C. They've made an attempt to make the credits more or less match the stock setiathome_enhanced, and the new server-side adapting multiplier will take care of equalizing the remaining difference. Once everything settles out, AP work will give a very constant credit since every WU gets the same processing.

D. The AstroPulse FAQ and the science details to which it links describe the application and what it's looking for quite well. Each WU contains 13.4217728 seconds of the full 2.5 MHz bandwidth data captured by the recorder. 
                                                              Joe
