Astropulse 601 task now at 55 hours and counting and yet still only 80% complete from an estimate that was a tiny fraction of this. Forecast completion on 9 hours and this reduces by just 5 mins for each hour of processing it seems.
the task is now overdue, how can I tell if the whole process is in error due to this excessive time, or will results be valid and useful eventually?
Task size estimated in properties to be 1.8M Gflops
On a 3Ghz AMD processor how long should it take?

Hi

You are running stock on a rather old AMD CPU.
Let it finnish, times seems about right for this CPU.

With each crime and every kindness we birth our future.

Astropulse progress is quite linear, so 55 hours at 80% indicates very close to 68 hours 45 minutes for the full run. That's reasonable for your CPU.

BOINC 7.2.42 strongly favors the original estimate in calculating its estimate of time to completion. Some projects have applications which give very poor progress values...

                                                                   Joe

If the task is overdue it will be sent out again to someone else, then if you report it and it validates the third task will get stuck when it reports.

I am running Astropulse with the Lunatics app. On my Opteron 1210 at 1.8 GHz it takes about 40 hours.

Toshiba Satelite P 200 2.1 GHZ Celeron Duo GT 7600 Nvida (NO Cuda) running AP's on both cores approx 30 hrs and that's with Dynamic frequency set to low (crashes otherwise ) so it's running at 1 GHZ for comparison..

Your computer shows 0 astropulse tasks. It looks like it was already assigned to another host, turned in, and deleted. I have a system similar to yours, but a bit slower. I have not run AP on it since AP v5, but I don't recall it taking 2-3 days to complete 1 AP task.

My daily driver is an AMD 4800+ which, at 2.5Ghz is just a bit slower than yours. Back when I was running stock AP, it used to take between 57 and 76 hours, depending on what else I was doing on the machine and whether any throttling was going on for temperature control.

Have you guys used optimized clients ?

They're almost mandatory in order to get decent performance, especially from older CPUs.

I just ran an Astropulse on an old notebook (Pentium M 1.86GHz) and it took it some whopping 61 hours to complete, using the stock linux client.

I'll dump some old Vista32 onto it and see what it can do with the latest optmized clients.

Yes all my machines are running Lunatics even the Lappy which has a problem and runs at harf speed but still faster than 61 hrs wow only 30 odd hrs on my stuffed Lappy

---

Yup, all my computers use them. Much faster turnaround times. A lot of the guys that write the Lunatics are contributors to the Seti standard apps. If the optimized apps show good results they eventually get migrated into the standard Seti apps. On my store bought home computer saw a 10 K increase in my RAC.(but results vary)

My old 1.5GHz Pentium M notebook does an AP in about 20 hours with Windows 7 x86. Using ap6_win_x86_sse2_cpu_r2137 optimized app.

That's not too shabby.

I'm expecting to bring mine back to life within the next 48hours and see what it gets me.

My Sempron 3200+ (1.8GHz) does APs in 44-46 hours using "AP6_win_x86_SSE3_CPU_r2137_all_opt_archSSE2.exe" Older CPUs aren't the greatest at running APs.

Using "AP6_win_x86_SSE_CPU_r1797.exe" my i5 2500K @3.4GHz and my i5 3570K do them in around 6.25hrs.

[edit] Maybe less if I wasn't feeding GPU's.

Cheers.

Thanks for encouragement
80% is now 9% with 65 hours gone and estimated 5 hours to go
so still 68 or 70 hours in total
where the 9% (as in nine not ninty) comes from is baffling

Maybe it started over for whatever reason? It happens from time to time, but should basically never happen.

started over ?????
it is now 68 Hrs 46 min with 9 hrs 21 to go (and rising faster than 1 sec per sec it seems) and on 16%, and now 7 days over due
Quite enough is enough I think
what a waste of resource !
I am cancelling the job and will immediately cancel any more Astropulse jobs as I receive them

Just go to your SETI@home preferences, http://setiathome.berkeley.edu/prefs.php?subset=project, and for "Run only the selected applications" change "AstroPulse v6:" to no. That way you won't get anymore. ;-

Cheers.

Probably for the best. I don't even see the AP on your list of work units in progress, error or anyplace else on your list. So I wonder if it was removed after the deadline was missed or if the 3rd person finished it and it validated then they removed it? Either way as you said, best to just cancel it. You might want to look at the lunatics optimized apps to speed up your work. That might help in the future. Sorry about all of that time wasted.
