Just to tease you guys... I've been crunching Astropulse only on this machine for the past month:

Just got my second AP this year, then the cricket graphs flatlined.

And I'm crunchin' AP only on my Lifebook for over a year now,
55 in queue (17 day cache) and I'm happy !

edit: my main rig needs refueling with only 74 AP's left.

however the frequency of AP production is so low that my quad core might sit idle for some time before i get anyting. Also the credits for the Ap's are a bit reduced so its not such a great benefit as it had in the past

This is true, but it's still a benefit. 800 AP credits vs. about 100 MB CPU, yet the run times on my host are only about 6x higher for 8x higher credit.

Yeah, on my Sempron 3400 cruncher, when its cache was completely drained two weeks ago, I edited the app_info to only have AP. After 18 hours of "no jobs available," I let it have MB again. Filled the 4-day cache in one request (all MBs).

This post may not be entirely suitable in this thread but I guess I will post it anyway. After the last outage, I have noticed that all the MB units that I got on my laptop are pseudo APs. They now take about 9 hours to process instead of the earlier ~2 hours. I double checked to make sure they are not AP, but these do behave like them. And the credits are higher too, 100+ instead of 20s.

Has anything changed in the way computation is done or is it just me?

The tasks you describe are VLAR's, or Very Low Angle Ratio.
They do take longer to crunch but as you say the reward is typically 100 to 150 ish credits.

Out of the 792 tasks on my i7 - I have 1 Astropulse.
First time this computer has ever crunched one.

Estimated to to completion: 16 hours 4 minutes.

Well, I guess my machine isn't as slow as I thought after seeing my wingman's time http://setiathome.berkeley.edu/workunit.php?wuid=585092345 My runtime was 95,902.79 and CPU time was 80,761.84 his was 244,011.63/243,331.00 He is running stock but a Xeon with 4 cores.

Not so sure about this next one though. After just a little under 15 hours it's only 26.5% done. Gonna be awhile it looks like.

When I guessed speed, I assumed a normal Astropulse WU, not one like 585092345 which reached the repetitive pulse limit during the first FFA. The optimized AP apps stop fishing for repetitive pulses once the limit has been caught, stock doesn't. Then the single pulse limit was reached at about 82% progress so both optimized and stock quit early. The WU also had no blanking to slow things down. In other words, don't expect runs under 27 hours often.

I just checked my main righttp://setiathome.berkeley.edu/show_host_detail.php?hostid=5266723 . It got 23 AP's and it's running 8 AP's high priority right now!

I set one of my hosts to run only AP and they proved to be not that rare - I have 43 tasks, completing 8 per day.

55 in queue (17 day cache) and I'm happy !

edit: my main rig needs refueling with only 74 AP's left.

After seeing what your T7200 @ 2.00GHz was doing with just Astropulse_v505,
I've run down the cache on my T8100 @ 2.10GHz, and removed the AK_V8 entries from my app_info,
i expect the final RAC will be similiar to your's as the run times are practically the same,

Gave running the cache down a try last week. Both rigs are doing ap-only right now. The single-core machine usually only has 3 at a time (4-day cache), but the main rig has 18-24. Been doing pretty well with r339. It is faster on my CPUs than r168 was by about 10%.

Ran the credits/sec math on AP vs MB, and it turns out that AP gives me 0.001 credits/sec more (about 10%) than MB does, and I seem to have run into a batch of 30 repetitive pulse units, and those end up giving about 0.004 credits/sec more than MB (nearly a 50% gain).

I was actually surprised to see how easy it was to get APs assigned. Almost every single work request ends up getting one.

Is rationing over!!!!
(or at least easing)

I almost fell over when I saw this morning that i had received an Astropulse task

So. I've pushed it up the queue and it's crunching ahead of it's allotted timing!!!

It must be about a year since I was sent the last Astropulse.

I'd almost been resigned to thinking my settings must have been incorrect without knowing why!!!
