The exact wording is important.
Does it say "Project has no work"?

********

There is a back off timer intended to limit hoarding of tasks, so that it's fairer to all users.
The timer is nominally 1 hour, but is actually 1 hour and (I think), 30 seconds.
Any contact with the server either starts the timer, or resets it to 1 hour, hence the "Don't keep clicking the Update button" advice.

And this latest lot was only 2 small batches, so the 10 thousand plus computers lying in wait for work have quickly grabbed all of them.

The Server Status page only updates about every 3 hours.


One of the problems for those of us getting work infrequently is the people with a large resource share and large cache, they fill their cache and the rest of us get the scraps BUT DON'T get me wrong...as long as they are producing valid results I have ZERO problems with this at all!!! It just means at other projects we get the units and they don't so it all works out in the end. For example I didn't get any units during the last year but I crunched ALOT of Covid units in that time frame!!!
What CPDN should do (if they're trying to make everybody get some) is limit the number of jobs handed to each host. Milkyway already does this, they limit the number of jobs you can queue up per GPU, no matter how big you set your buffer or how fast you can do them, or how many you run on the GPU at once.

The 3 Windows batches are showing early signs of failures, but no hard fails yet, so I can't see what the problem is.

One of my PCs grabbed one of that first batch. It errored out with a Signal 11 between the 5th and 6th trickles.


Each of the three most recent Windows batches have one success so far. Two on I5 machines, one on an I7 the last being one of Ian's machines.
Nothing's crashed here yet. My i5 is up to 65% on each of 6 tasks. But two thirds was around where most of the SAFR ones crashed.

Yes! Painfully reconstructing new Windows 10 machine that finished one from batch #894 — and that was without the SSD that’s finally arrived (after being delayed by you-know-what).
I've had no problem getting computer parts. Parrots, yes, but not computer parts. Only one pet shop was prepared to break the rules and sell me some. There's the usual nonsense with people hoarding food and toilet rolls, but who cares? I just buy a different flavour.

I haven't either. But we just got a Christmas card yesterday, mailed the day before.
That is common in the U.S., for the fast delivery routes. Others may take longer.

Er... I don't understand. You're saying the mail company took 1 day, but your friend took until yesterday to post it? We're used to next day delivery in the UK, but it's a shorter distance.

Last month I got a bill in the mail. I sent a check in payment the very next day and got a late fee of over $20. Well, they got it late and cleared it as soon as they got it. But the post office held it up.

One of the things that Trumps Postmaster General did last year was sabotage the mail system in an effort to prevent people from voting by mail. It didn’t work, the mail-in ballots killed him, but it did slow down the mail quite a bit.

What he should have done is shut down the USPS. From what I hear they need some competition to give them a kick up the behind. The UK doesn't have problems with slow mail or expensive prices, as we have 10 competing couriers.

We didn't have problems with slow mail or expensive prices before we had 10 competing couriers.

Yes we did, the Royal Mail have always been and still are way too expensive. I never send parcels more than about 500g with them. If I was to post you a graphics card for example, which weighs a little over 2kg, I'd use Hermes for £6.66, not Royal Mail for £9.70.

Funnily enough I sent a graphics card Royal Mail today - it weighed 1.093 kg and cost me £3.20

Royal Mail are ok for light stuff, then the prices shoot up. I was talking about the big graphics cards, the ones with three fans and a heatsink the size of a VHS cassette, once you pack them in a box, the package is over 2kg.

I once tried to ship a computer (big heavy gaming machine, with insurance for £1000). Royal Mail said too heavy, Parcel Force wanted £120(!), Parcel Monkey did it for £30.

The other thing I hate about the Royal Mail is their pedantry. Very few people have a precise scale, so if I take something in that I'm sure weighs 85g, they'll claim it's 101g, and therefore over the 100g limit. If I don't take it in and just post it, the receiving end ends up with an £8 charge due to a 20p shortage on stamps. They're beyond a joke.

Yes, my i5 finished 5 today and 1 in a few hours time. But the newer chips like Ryzens are slower per core. As for anyone without a fast machine, they're going to be a while. My Xeon X5650s for example look like they'll take 40 days, which is longer than the SAFR ones! Which is weird, as the i5 is faster with the EU ones. Different programming?

My 3 I5 2.6 GHz laptops seem on track to finish the batch 892 WU’s in about 5.5 to 6 days. This is running them on only 2 cores on each not all 4.

[Peter Hucker wrote:]... Different programming?

The SAFR region is larger than the EU one and the recent SAFR models 24 months instead of 13 months for the EU models. A factor going the other way is that the resolution of the recent EU models is double that of the SAFR models.

The resulting estimated Gflops difference is listed below with a correction factor based on my machines.

SAFR50/24 = 7,694,788 Gflops (/ 2.39)


EU25/13 = 2,061,502 Gflops (/ 0.67)


Thus, for example, the SAFR/EU ratio for CPU time on my machines is expected to be (7,694,788 / 2.39) / (2,061,502 / 0.67) = 1.05.

The ratio for two models that finished on one of my machines from batch #890 (SAFR/24) and batch #894 (EU25/13) was 345,907.20 / 319,405.60 = 1.08 - i.e. about as expected.
