I was getting that yesterday, time after time. Just give it 30 minutes and do a manual update. Maybe try every 15 minutes -- after a while I did get new work. |

I cycled a little faster than that and got one after about 15 min or so ... so, not sure if the speed is the key or the persistence ... and I just got another on the second call to GPU Grid so now I have one ... make that two in the queue ...
I think the feeder "clog" issue is back ... where the feeder gets full of one and only one type of task instead of retaining a balance. I suggested several changes years ago ... ah well ... it is sure acting like the queue gets full of tasks for the PS3 and has no room for the tasks for the PCs ... unless they are the same tasks?
Only the hairdresser knows for sure ...
Anyway, I am back running with one in work and two in queue ... |

Trying now since over an hour to get a WU with all tricks, no luck... :-\
It gets really annoying with the time.
Edit:
Finally managed to get one, yay.

The computer with the 9800 GT is working on its last, though that is likely to keep it occupied until well into tomorrow ...
The GTC 280 has one more in the queue so it should be running out sometime tonight ... I will have to wait and see if I have to get prayer beads out again ...
In other news, WCG's having server problems for the first time in my memory that has lasted more than a few minutes ... so, I have about 3 days of CEP tasks done and in holding ...
Mind Modeling is also off line ...
The good news, the stress on SIMAP with a high resource share is paying handsome dividends as the growth in the Cobblestones earned is rising nicely (thank you), with a possibility that we may be able to see an increase of as much as 20K in the total.
Other focus projects are likewise seeing more modest gains but even there the increases are heartwarming ...
In sports, the inability to save community preferences continues for more than 20 straight days so you cannot see the glory of my signature ...
Stay tuned ... a special comment may be on the horizon ... |

Before the change in the feeder we did not have a single issue which you seem to describe. Sometimes there was no GPU work, but it had just ran dry and the creation of new ones had to be issued manually. There was no strange clogging. And we know the feeder has the bug of not sending work to clients even if there are enough WUs in the queue. So I assume what we're seeing here is just more of the same.
Interesting question though, are the WUs the same? I'd suppose not, but could they be the same? Would one want this? But I digress.

Well, if it would mean I would get work without hassle, then sure I would want them the same. But, I am suspicious that they are not ... some are tagged to go to PS3s and some to the GPU machines. If this is the case then you can get the case where the feeder gets full of PS3 tasks and none for the GPUs ... (or vice versa) ... in this case you have to wait until the PS3 users pull off enough tasks and that some GPU tasks get into the queue.
I forget the project (Rosetta?) but they had this issue where they had tasks of two types and the queue would fill with tasks all of one type and the actual usage was that the other type was pulled faster ... so, you had the problem that if the feeder was pulling in the wrong "mix" of tasks then people were starved.
There was some fiddling with the feeder but no serious work on it at the time ... as far as I know the minor tweak and the fact that the project increased the queue size "solved" the problem. Another case of not actually fixing the problem but just fiddling with the system until it limps along some more ...
What really should be happening in an environment with mixed workloads is that there should be separate queues in the feeder one for each class of work ... then the appropriate list would be queried for the work ... one could argue that this would also allow a shorter total queue length for the sum total of the queues ... but I digress ... |

I think the number of participants has increased quite dramatically from under 1,000 to over 1,300 in the last two months so unless the number of WU's being issued has increased proportionally this may be a factor as well... ( problems with the SETI cuda program may be sending some this way...) |

It would seem natural to use different WUs for PS3 and GPU, especially since until recently we still had the "GPUTEST"-WUs. But using the same WUs for both would certainly benefit project performance due to better load balancing.. if it wouldn't introduce all kinds of new problems.
Regarding the feeder issue.. I still think there are no signs of "the feeder gets full of PS3 tasks and none for the GPUs", but I can't know. I'll forward the question ;)
And, yes, having separate queues is definitely the way to go. That's simple, robust, elegant. Anything else is just tinkering.

Dear Paul,
thanks for this suggestion. It was actually the same case for us. BOINC people from Berkeley helped us understanding it the same day that ETA pointed me to your message after my holidays.
thanks.

you are most welcome ... just don't tell UCB I was anywhere near your project ... :)
Now, about that 6.56 app ... :) |
