The deadline is very short for work units like these, I have four running, none will be finished by the given deadline, (which I see is also shorter than the MCM work units). This is a 4GHz i7. If you've been sent retries or tasks for some lower-generation work-units they will have shorter deadlines. Unfortunately, the enormous periods of time it might have taken for all the necessary files to download doesn't help because the main BOINC server sets the deadline based on request time, not completed downloads time (which it doesn't know). As long as the tasks have started and passed a checkpoint they should be allowed to complete. However, be aware that given the problems some of us are having getting downloads at all, there's always a danger that the entire work-unit might be written off as faulty if the BOINC server sees too many errors (due to failed downloads...) I know it's not "good news" but it is what it is -- at least you managed to get some ARP1 work :-) (said he, twiddling his thumbs waiting 12 to 24 hours for files to download, and then finding that one of them got truncated so that time was doubly wasted!) Cheers - Al. |

Currently I am having more problems with uploads than downloads. Uploads are accumulating faster than they are uploading and that is with just one task running. Once my CPDN work runs down a bit, and more cores will be taking on ARP tasks I expect this to get worse!

Take the challenge ARP1 second half of November 2024 and return as many ARP1-results as you can.
---------------------------------------- And don't abort your ARP1-tasks!!!Adri PS I found I was late for the November challenge, so I created the one for the second half of November. [Edit 1 times, last edit by adriverhoef at Nov 17, 2024 12:53:24 PM] |

And don't abort your ARP1-tasks!!!Adri PS I found I was late for the November challenge, so I created the one for the second half of November. A noble effort, but I think a bit misguided at this point. Since Krembil's infrastructure is mostly incapable of handling the current load, encouraging more crunching of ARP will just exacerbate the current problems. Cheers

The data from the project is far too old because the climate has changed significantly in the last 4 years and your servers cannot handle the load and thus hinder other projects

Take the challenge ARP1 second half of November 2024 and return as many ARP1-results as you can. Seriously? And don't abort your ARP1-tasks!!!Adri PS I found I was late for the November challenge, so I created the one for the second half of November.  This weekend it has been a challenge to even return those few ARP1 WUs that one was able to successfully download and now we are at the point where MCM1 WUs are starting to constantly choke on upload and thus won't get any new ones in the first place.... smh, Ralf  |

The data from the project is far too old because the climate has changed significantly in the last 4 years and your servers cannot handle the load and thus hinder other projects Agreed about the capacity problems; that said, I rather suspect that it doesn't really matter how long it takes to finish now...The time period being modelled was already going to be historical when the project actually started (given the likely duration without problems), so the objective was [presumably] to see whether the modelling technique would be a reasonable fit for the reality, and for how far in advance. Whether that goal is achieved remains to be seen, and whether the changes in "initial conditions" would be modelled successfully is, indeed, another matter! Cheers - Al. P.S. -- It's someone's research project! I very much doubt that live forecasting would be done using distributed computing :-) |
