I have a desktop with a celeron 2.4Ghz single processor. Its running some flavor of ubuntu. BOINC is the only thing running on the machine besides the normal background apps. It takes a while but it has finished all the other tasks given it. It downloaded an ARP project on the 4th and the deadline is the 11th. Today is the 9th and it says its done about 38%. It states that it has 110 hrs left. Obviously its not going to finish on time. Do I need to abort ?

When that machine would be running 24/7, it would finish an ARP1 within 7 days.
----------------------------------------I suppose that machine is shutdown every now and then. Cause an ARP-task only makes a checkpoint every 12.5% of progress, you'll loose a lot of cpu-time. You could consider not to shutdown that machine for the time being or shutdown with hibernation keeping the task in memory. For the future disable ARP's in your project preferences.  |

I immediately restarted. Its in my laundry room without a monitor. I went to check on it today because it had run for 5 days and all my other machines (I have 5 total so far) had finished their ARP files. Is there a way to restrict just this machine from running ARP files? Once I get my bronze for this one I am moving on from it altogether. Lastly, I still do not know if I should abort this one?

There is a risk that after the deadline a resend is sent to a fast and quick returning machine. When you have not returned your task before that resend returns, you probably will not get the credits for it. It's up to you. |

Long as the result is still on the life list credit is granted, and it's documented up with that case that ran 160 hours. All 3 got credit. Seem to recall if no longer life the 'late' reported task gets a 'no longer needed' or 'not found', something to that effect. [Edit 1 times, last edit by Former Member at Sep 10, 2020 12:16:07 AM] |

If a unit is past its deadline the resend would have a deadline of half the original and so would go to a machine that regularly returns within that shorter timescale, so you might have up to a further 3.5 days to complete it, but no guarantee.

I guess now I have a Ryzen7, it makes sense for me to retire my old and very much slower laptop from this project. Currently running five ARP tasks at a time on it, leaving one core free. Perhaps deadline should be shorter still to restrict the tasks to faster machines?

While I have run some work for CPDN in the past I am very new to ARP and WCG. After I returned my 25000th result for OPN I decided to open up my systems to the other active projects. I noticed that ARP was only running one task at a time on my systems so I set up a second profile to give one system over to ARP exclusively and then increased the number of ARP jobs allowed in the Default profile.
Today I noticed my laptop was bogging down and went to investigate. It seems it doesn't have enough RAM to run more than 2 ARP tasks at once. It is also taking 40+ hours of uninterrupted computing to complete them. So the morale of the story is don't run ARP tasks on a seven year old laptop with 4GB of RAM and an AMD A6 6310 APU unless that is all you want it to do. |

I've pretty much dedicated the old war (plow) horse to crunching and while it's a bit slow (40-50 hrs/task) it does progress me along the badge path. Granted the progress seems more significant for the earlier badges. When it wears out I'll recycle it but in the meantime it just sits in the corner doing it's thing 24x7.  |
