I was getting "no work from project" up until 01:59:46. Then I managed to grab 60 work units on one machine and by 02:02:51 it was all sold out and back to "no work from project" again.

Lucky me.

yes lucky you. I got some too, on 2 out of my 11 machines.

Usually it is a bit of a lottery getting work whe it is a small release like this one, as the program that puts the work onto the server does so gradually. So there might be 60 jobs waiting, then you get them all, and the next instat someone else gets none, but a few minutes later there are a few more waiting.

This explains why my two boxes got work at 2:02:39 and 2:03:10 UTC on the LHC server clock, where one of yours failed to get any at 02:02:51.

This kind of effect also explains why the faster machine out of my two lucky ones got less work than the even slower one - at 02:03:10 i emptied the barrel of all the jobs that had arrived since your box looked at 02:02:51 (less any that other people got). 12 jobs in 19 seconds, plus whatever was handed out to others in that 19sec.

I am pleased as my boxes have been off for almost a week, and I got them back on only 10hours before the work came :)

edit: add:

ps - you may be interested in Scarecrow's graphs - they have a time resolution of 1 hour so miss this knd of fine detail, but are good at seeing the longer term picture

Yeah, I got 10 WU's across 4 machines attached. Propably some kind of test run...

We'll see.. but ... LHC is still alive.. :-) nice to see that... :-)

---

I received 33 wu's at about 5 pm PST. Wu-Hoo!

---

I got nothing, cause i was sleeping and not aware that LHC will spill out work again. I hope there will be more soon.

I was sleeping too - UTC is my home timezone & I got up in the night as we do sometimes and noticed that BoincView was showing me 2 boxes with LHC. But it all happened without my conscious involvement around 90mins earlier.

My advice (should you choose to accept it) is as follows:

* sensible cache size (from 0.1 to 0.5 day unless you *really* need longer for a dialup etc)

* give LHC a double share of the resources so it is always "starved" by the time work is available. If all other projects are at the default resource level of 100, give LHC 200 for example. If your other projects vary in resources, give LHC double the average.

* leave LHC enabled all the time

* choose other projects that have run lengths of around your cache size (or on Rosetta choose a run length roughly matcing your cache size)

That way if work is on the system continuously for >4hrs you will get a fair share, if work is on the system for <4hrs (as here) you get a fair go at the "lottery" for it. And you will get that work whether you are nursmaiding your boxes lovingly, or in bed pushing up the ZZZs or out on the town.

Large caches mean that if you get work you get more, but also mean that your box will go look for work less often, so you'd be less likely to ask at just the right time. Large caches also mean you get heavy flak from those who like to shout about greedy users, whereas little and often gets the same result in the long term and without embarrassment in the forums (fora?)

HTH

There should be a bigger chunk coming through soon(day or two). I will try to keep you all updated but sometimes I find out at the last possible minute, our biggest contributor is based in Vancouver so a *slightly* different time zone to the one I'm used to.

I got 7 WU's, I have the same "stategy" as River~~.

Yeah, lucky. Will you end all 60 workunits in a sensible amount of time?

look at his host stats, he already finished all 60.

And i am out of luck, another spill just minutes ago and i didn't get some either.

and I got just 1, on a third box, making a totla of 22 WU today, so 3/11 boxes got lucky in these 24hrs so far and avg over all my boxes is 2 wu each today.

The thing about having lots of slow boxes (11 boxes all 0.5 to 0.866 GHz) is I don't get many but I usually get some... and in the meantime they keep my lounge nice and warm

R~~

edit 0.5 MHz -> 0.5 GHz :)

The sixty I got were entirely down to the BOINC application. I did nothing to provoke it. So yes, I did manage to finish all 60. As it happened it took about seven or eight hours of CPU. Though it took around nine hours for them all to be reported and acknowledged. I guess it would have downloaded more, if there had been more at the time, given how short each one was.

Weird.

BOINC says "no work from project" when I update, but frontpage says ~40,000 WU available. What gives?

Not wierd at all!! :). Just read it more carefully!! :)

The front page says that there are approximately 40,000 results in progress. This means they are out there on user machines being done. Currently there are no more to send.

well, those WU's got sent out quick.... impressive.... sounds like many machines attached banging the LHC front door all the time...

---

At first glance, yes, it appears impressive, but when you look into it, it's not that surprising. Compared with past runs, the WUs seem to be of very short duration so that a machine asking for a day's work gets a whole bunch.

I've noticed several of my machines that got a sizeable number each but have now finished them all.

Argh.

Reading is hard.

And my other machine just picked up forty this morning using the same method.

I too find that the world is a much better place when I rely on my assumptions. All the problems only start when this disillusionment stuff comes in ...

I've got five wu's on my main and 20 on my secound pc.
