Congratulations... You deserve a pat on the back for persevering, thanks for posting and allowing us to share your experience. I hope you don't mind that I point to your AP WU, wuid=309347223. The best thing about AP WUs seems to be that extended runtimes might fill in gaps of lean WU splitting and server outages. On the otherside... some might say that the lack of work is being caused by AP WU splitting and distribution. Comparing CPU times and credit claims of MB and AP WUs on your host, it looks like AP is underclaiming MB stock client by ~40%. As this is supposed to be addressed with the "adjustable" sliding multiplier within 30 days to narrow the gap, it seems that the early adopters are paying a premium to be the "guinea pigs". This is just the opposite of what I would expect; If the project administrators wanted to gain acceptance it seems they would be paying a premium in credits at first and allow the gap to narrow from the other direction. Folks might then be more accomodating to crunching AP during these "early" days; Especially considering the earlier distribution of "ghosts" and guaranteed missed deadlines due to issuing AP work to underqualified hosts. Just my opinion, JDWhale I agree, plus they never finish on my machines. They get to a point and continue to clock time, but the time to finish doesn't change and the percentage done doesn't change. I'm not talking about staring at it for 5 minutes, I mean all day while I'm at work. After that happened on both of my machines, I just started aborting them when I saw them, why waste cpu time on a process that won't finish? But then I ended up with no work because they are such beasts they loaded down my work load quota. For the past two days my machines had nothing to do. So I've switched to Einstein on both of my computers.

Because you have been running MB units, your DCF is set really low. AP units seem to have a decent estimate of time if your DCF is around .4 or so. It's not unusual for them to take about 140 hours or so. IMHO, this is really a good thing as most users start running AP units, it will lessen the loads on the servers. Please reconsider as AP is doing valid research as well. Wendy, The issue I see is they don't seem to complete on my system at all. They just run for many hours then seem to stop or make no progress as the clock continues to tick. While the standard work units click away on the other processor. Worse yet, because they are so much work, they also fill the queue and there are no other work units available for the second processor when it finishes up its current WUs. Right now my one machine has nothing to do and hasn't had anything for many hours. It would be nice if we could choose to ignore them somehow. Right now I've "wasted" 100+ hours with the AP units. ~Joe
4) Message boards : Number crunching : AstroPulse errors - Reporting (Message 796757) Posted 12 Aug 2008 by JSabin Post: Astropulse projects hang up on my system after spending tens of hours on them. I've had this happen three times now. In the future, if I see them in my queue, I'll just delete them. Anyone else having this issue?
5) Message boards : Number crunching : Nothing changed, but processing slows to 1/2 speed (Message 688368) Posted 3 Dec 2007 by JSabin Post: At onen point I experienced my one computer slowing down to about 1/2 speed. I don't know what caused it, but things took much longer than in the past. That appeared to happen again. However, this time it was just a series of WUs that took long in relation to credit. None had been crunched by another computer at first post, so I couldn't tell if I was crunching them in proportion. Rather it was easier to jump to the conclusion that my system was somehow processing slower. :) Thanks for the info, it helps to understand this a little better. I'm sure many others are curious what's going on. Of course if I was curious enough I'd grab a copy of the code and look.
6) Message boards : Number crunching : Nothing changed, but processing slows to 1/2 speed (Message 687868) Posted 2 Dec 2007 by JSabin Post: Sorry to be unclear. I meant duration of the actual task. And now the correction factor is twice as high too. Meaning that my computer is actually computing tasks slower approx. by a factor of 2. However, it seems like there were some low value tasks that took a lot of ocmputing power. I'm not sure how that value is calculated, but things look like they are on track again.
7) Message boards : Number crunching : Nothing changed, but processing slows to 1/2 speed (Message 687683) Posted 2 Dec 2007 by JSabin Post: This has happened in the past, BOINC will process quickly through WUs and then it will take at least 2 times as long. Nothing else has changed. BOINC still gets 100% cpu, but processes take twice as long. My one computer has gone from .24 duration to .5 something. Does anyone know why this happens?
8) Questions and Answers : Windows : I give up on Seti (Message 667145) Posted 26 Oct 2007 by JSabin Post: The other projects do not restart from 0% all the time Seti does. OK, that doesn't help me. I need more information as to how you're determining that SETI@Home restarts, as per my question in my first response. Do you see something in a result file that leads you to believe that SETI has restarted? Do you see the graphic display or screen saver start over at 0%? Is the progress indicator in BOINC Manager starting over at 0%? There may be an explanation for what you are seeing, depending on what you are seeing. If not, there may be a problem that we need to resolve, but we need to know what it is you're seeing first. I can assure you that the project starts over at or close to 0% if one does not have the CPU usage set to 100%. See my other post on this thread for further info. Intel T5300 core 2 processor, windows xp pro operating system sp 2. 1 gig memory.
9) Questions and Answers : Windows : I give up on Seti (Message 667067) Posted 26 Oct 2007 by JSabin Post: I too have given up. I have found the following to be true: 1. at 100% processor my computers overheat, none are over clocked, two are laptops. 2. at less than 100% WUs will reset back to 0% and start over. Ultimately completing, but taking 40-80% more CPU time to do so. 3. I found that I can turn off one of the CPUs to BOINC the processors won't overheat, but often WUs will begin processing backwards and taking very long periods of time to complete. e.g. one WU when two processors are enabled will complete in 3 hours (when estimated to take 3:15) however if I turn it to just one cpu, the same WU time will still say 3:15, but will take 7 hours. So with two cpu enable machine will do two WU in 3 hours, but one cpu will do one WU in 7 hours. Go figure. Based on #3, I thought I got a bunch of bad WUs and terminated them as they ran backwards. They'd literally get to 40% and then start counting % done backwards and time remaining upwards for a while, then start moving forward again. I killed a bunch, then discovered they eventually finished. So I think #3 is a variation of the bug #2. Thus I have taken BOINC off all my computers after they finished processing their last WUs (as of 16:30 UT today). Thanks for the fun, it was fun, but the frustration of dealing with the bugs and overheating have become more effort than the fun. Good luck all! Perhaps this will get worked out and then I'll come back. Joe
10) Questions and Answers : Windows : Computer with consistent under valued claimed credit (Message 664602) Posted 22 Oct 2007 by JSabin Post: I find that my computer agrees with most of the other SETI computers on claimed credit. However I just had one claim 37 when mine claimed 54. I took a look at their other results and they were equally under valued. Same build Windows, so what gives, anyone know?
11) Questions and Answers : Windows : How does one correctly update to a newer version of BOINC (Message 662725) Posted 19 Oct 2007 by JSabin Post: OK, so that's what I did, but then it wouldn't start, so I uninstalled and reinstalled. That seems to be when it detached...Oh well.
12) Questions and Answers : Windows : How does one correctly update to a newer version of BOINC (Message 662705) Posted 19 Oct 2007 by JSabin Post: OK, I've learned one of the ways NOT to do it. Anyway, I won't admit what I did, really I won't so don't ask. But I do have the latest running on all my machines now, but one detached in the process. So, what is the "best" way to do so? Thanks!
13) Message boards : Cafe SETI : Curious RAC:Pending ratio (Message 662049) Posted 18 Oct 2007 by JSabin Post: This was just for fun actually, which is why I posted it here. Just curious as to what others see as the pending vs the credited RAC.
14) Message boards : Cafe SETI : Curious RAC:Pending ratio (Message 661925) Posted 18 Oct 2007 by JSabin Post: I'm wondering what others see as a RAC:Pending credit ratio. Mine is running about 1:4. right now I'm also at about 10% pending to earned credit. I've been participating again for about two months and enjoying the process. I like the new system.
15) Message boards : Number crunching : Restarting WUs (Message 659648) Posted 14 Oct 2007 by JSabin Post: Thanks for all your suggestions. It turned out to be the computer would turn the active session inactive and go to the login page. It left the programs active, but upon return BOINC reset one of the WUs to 0. I turned off that function and it seems to be working properly. Thanks! Joe
16) Message boards : Number crunching : Restarting WUs (Message 659550) Posted 14 Oct 2007 by JSabin Post: I've got a new computer and it will restart WUs. By that I mean it will be cranking along 50% done or so and then start over at 0%. Ultimately these finish, but they may cycle once or twice. Some, on the other hand, just run right through. Thoughts?
17) Questions and Answers : Windows : BOINC breaks WIN XP Pro ??? (Message 653760) Posted 4 Oct 2007 by JSabin Post: I've had my computer for about four years. It's been solid. I installed BOINC and after about a week the computer blue screened. I recovered and after a few more days it blue screened again. I recovered and removed BOINC and the computer ran fine for a week. I reinstalled BOINC and it blue screened again after a day. Reboot, recover and it ran for a while (a few days) and blue screened again. This time requiring a full recovery of the hard drive and Win XP system. The system wouldn't reboot at first. After many hours of recovery the system is back up and running. ??? Is BOINC breaking other Win XP Pro installs?
18) Questions and Answers : Windows : WU Allocation (Message 628759) Posted 29 Aug 2007 by JSabin Post: Thanks, I'm just bumping it to 1/2 a day. I've never run out of work for longer than a few hours. My office machine in particular when there are communications problems. I think it makes sense to have the work on hand a little greater than the average turnaround time for the computer. That's what was causing the issues on my office computer. Not being greedy, just trying to keep the cpus busy. :)
19) Questions and Answers : Windows : WU Allocation (Message 628587) Posted 29 Aug 2007 by JSabin Post: connect every 0.1 enough work for 0.25 <--- There's the issue, I'll bump that a bit. Edit: yes set to work while computer in use. That's functioning well. Thanks I didn't notice that maintain work for setting.
20) Questions and Answers : Windows : WU Allocation (Message 628559) Posted 29 Aug 2007 by JSabin Post: What's the deal with WU allocation? My two machines often only get a new WU an hour or so before the current one is finished. That's assuming I can connect. While I see other noobs with 40+ WU and they haven't finished one. I don't get it. Right now my home computer has nothing to work on for the past few hours. My office computer ran out during the day today. My work computer is pumping through WUs when it has them. Is there something I can change on my computer to download a bit more work so I don't run out?
