Hi everyone,

I've managed to complete 2 WUs so far, but my third WU has run for over 4 days and only reached 70%. Its deadline is tomorrow afternoon.

If the system recognises a WU in progress and allows extra time to complete, then all is well.

If not, then I won't be able to justify burning so much CPU only to have the eventual result disregarded and/or receiving no credit for the eventual result returned.

This would be a great shame as this is such an interesting search in which to participate.

Any thoughts ?

Variable deadlines are used here for systems that take a little extra time.
WW's deadline is 7 days (up to 30 days). So as long as you are making progress you have nothing to worry about until the 30 day mark. Even at day 30 you may still be fine. As long as the work unit is active in the system you can return a result. How long it stays active depends on how long it takes for two matching valid results to be returned.

I absolutely agree with Monkeydee. And you can see your deadline as it becomes extended again and again, here: https://www.primegrid.com/results.php?userid=9029&show_names=1&appid=33 (I inserted your ID in that address, so it should work just for you). Green (meaning still not expired) date and time under Time reported
or deadline. /JeppeSN

Thank you SO MUCH both, that's excellent news on both counts.

I really had no idea that you could see deadline extensions - you learn something every day, even after 13 years of number crunching :-)

The Linux BOINC Manager ( I'm currently on v7.16.14 ) only shows the original deadline and not ( AFAIK ) any amended versions hence my original concern.

Cheers.
