1) Message boards : Number crunching : N-Body long processing time (Message 62252) Posted 3 Sep 2014 by John Black Post: Good call Mikey. I have followed your instructions and now I am getting tasks that I CAN calculate. No more aborted tasks I am happy and MW@H is happy.

2) Message boards : Number crunching : N-Body long processing time (Message 62205) Posted 22 Aug 2014 by John Black Post: Hi, what is wrong with these N body tasks. I have, a record, for me, a task of 113 hours processing time. I also have a few that have been calculated that produce no results i.e. 6 Validation inconclusive and 2 Cant validate. The estinated calculation times are also rubbish sometimes when I reach it I have only done 10% of the task. I am running a dual core and have already contacted the guy who posted these tasks when around about 6th August all the tasks were erroring out who advised me to abort them. I think that I may stop calculating these until they have been removed from the task list as I dont like to abortthem. John p.s. I tried to post an image with this but I dont know how to do it. I have the .jpg but cannot post it here

5) Message boards : Number crunching : CPU Calculation errors on ps-separation tasks (Message 60856) Posted 29 Jan 2014 by John Black Post: Hi Penguin5540, yeah nobody seems to have any ideas what is going wrong with these tasks. That said I am now getting some sort of result that the system is accepting, though, when I look at the wingmates result they seem sort of different to me. I am no expert at what the dupe should look like in fact in some cases there is no dupe??? I am going to bash on and see what happens. Thanks for at least commenting Regards John

6) Message boards : Number crunching : CPU Calculation errors on ps-separation tasks (Message 60808) Posted 25 Jan 2014 by John Black Post: Hi again, it seems that my problems have gone as the latest tasks are working ok. I have no idea what caused the calculation errors but, as I have not changed my set up, it must have been a faulty batch of tasks?? Anyway they seem to be working ok now. John

8) Message boards : News : New Separation Runs (Message 60764) Posted 18 Jan 2014 by John Black Post: Hi Matthew, if you look at my post in Number Crunching http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3448&postid=60753 you will see that I am getting nothing but errors on my CPU with these runs. I see that some people, mainly using GPUs, are getting results. I have had no problems with other MW@H runs or with my SETI stuff so I think that the errors are due to the runs themselves not working on my CPU. I now have about 12 errors and counting. Can you suggest what I should do about this, other than suspending these tasks? Thanks for your help John

9) Message boards : Number crunching : CPU Calculation errors on ps-separation tasks (Message 60754) Posted 16 Jan 2014 by John Black Post: Hi again, I now have had 5 calculation failures on the trot so I am going to stop calculating in the hope that we can find an answer on this thread.

11) Message boards : News : New Separation Runs Started (Message 59121) Posted 26 Jun 2013 by John Black Post: Thanks Link, I am running at 100%. I have looked at process explorer and task manager and think that a proprietary backup system from Acer has been hanging on to my processing time. I have stopped it and hope to see a difference over the next 24 hours. I have checked the SET@H results and the are now showing a lack of CPU time as well. It looks as if that is the solution. Apologies to Jeffery it seems to have been a coincidence that the separation runs came along at the same time as this program started to hang. Thanks to all for the input. John

12) Message boards : News : New Separation Runs Started (Message 59106) Posted 25 Jun 2013 by John Black Post: Ok Jeffery, the unit that gave me the trouble is 387829872. For 5,000 odd cpu with Milky way I would normally expect about 7,000 odd total time not 70,000 odd so something is wrong somewhere. It is an old E4700 dual core Acer but I run it 24/7 I don't run games or watch TV or anything like that the only other thing running on the second core is SETI@H and I have been running both successfully for years. There is something different with that wu? What I will do is to start one of the other 6 and see what happens but if it runs for 18 hours then I will have to call it quits and see if I can download something with a shorter run time. Thanks for your input I will post here if there are any developments. John

13) Message boards : News : New Separation Runs Started (Message 59099) Posted 25 Jun 2013 by John Black Post: Thanks Jeffrey, I am set not to use the GPU as, since I started with BOINC, my GPU was too weak to recommend its use. I really do not want to receive GPU tasks. The Runtime was 73,811 and the CPUtime was 5,933 so I do not know what was going on in all these blank seconds. When I looked at the task and work number I noticed that there were no results from a wingman even though it has been validated. Please see Task 508422281 and wu 387829872. If the other 5 are like this then I am not sure that I should crunch them. Please advise me how to proceed. John

14) Message boards : News : New Separation Runs Started (Message 59096) Posted 25 Jun 2013 by John Black Post: Hi Jeffrey, is there something wrong with these runs? I have six and the first has been running on my CPU for 17 hours and still only 90% complete. I checked the progress that others have had with these separation wus and it seems that no one has had any success. I will continue to plod on and report back here if I have any progress. John

I have a E4700 dual core and a wee GPU that is set to receive no tasks. I am now running solely S@H on both cores as I am receiving no CPU tasks from MW@H. I am not complaining as I still have SETI to fall back on, I am just keeping you informed. Thanks for all your hard work, moving is never easy. John
