as the title suggests , my only crunching machine will get a few units, crunch them in a minute or so and then sit there for 15 minutes without downloading any more

is there any setting i can add to make it poll for more work more frequently?

when i do a manual "update" then i get another few minutes of work

hope someone can can help :-)

cheers

Adrian,

There is a similar thread elsewhere and it seems MW will only allow three tasks per core and irrespective of how slow or fast these will be processed.

See the following: http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3698

Anthony.

thanks for taking the time to reply

BOINC Manager will always fetch new work after a completed task is uploaded. As a result, you should not have this problem unless no new tasks are available from the server for download.

With my installation, it checks once again a minute later for another fetch in the event the first fetch failed.

Mine asks for new GPU work with every upload, but sometimes the server does not give any. Is the project that starved for work units?

I guess so, the server status shows under 1000 wu available. I'm a bit surprised, thats almost CPDN bare.

I reckon its a combination of a work unit shortage and the very quick turnover in WU...

shame cos i have the fastest rig here and its barely heating the room

I see the same problem. It is not a new problem either, it has existed many years. Sometimes it happens because the project releases bad work, that errors out, which makes the server not give out new work. This seems to be the case for me right now. Check your tasks in your account for errors. This project is kind of sloppy, which takes getting used to. Overclocking may also be a culprit regarding errors.

I'm experiencing the same problem right now. Only getting a few units, sometimes my queues are empty.

Not sure if it is the same problem I have. I get about 60 units and when I return them, I don't get any new ones and then I run out of units. So I ended up created a job in Windows Task Scheduler which send an update command every 5 minutes. Since then, the only time I ran out of units was due to the fact that none were available.

I'm not sure you should be saying that out loud...you are essentially tying up the MW Server for YOU and not letting the rest of us in. It's not like each connection doesn't use Server time or the ports we connect on are unlimited, with 21,509 active users you could be the reason I can't get thru sometimes, and THAT'S why the backoff was implemented back in the day. I understand it works for you, but you are sequentially saying 'I am more important that you are and I want MY UNITS and I wan then NOW. That is not what the Project wants though, they want ALL of us to be at least somewhat happy. I'm just saying you want to NOT give away all your secrets in a public forum.

Actually it's important that the project leader(s) hear that people are frustrated and trying to cheat the system. This allows them to manage the cheating. Someones telling them they're calling in extra because xxx.
Now they now why there's an extra load on that server without having to research for hours.
If people can't get enough work they'll move on to other projects. So, either this project has more processing power than it needs, which is a good position to be in, or it has a project problem where it can't turn work around fast enough and the developers need to explain what's going on. Communication from the Project Leader is just as important as developing the code to fix the problem.
Thanks for reminding people of the impact of what they think might be a quick fix, doesn't necessarily help the system if everyone tries the same thing.

I was careful NOT to say he was 'cheating', he was taking advantage of a Windows feature that let him do things, 'cheating' implies he is doing something illegally, he isn't. What he IS doing is going around the established protocols and potentially causing problems for the rest of us, but this is all due to the Project having problems. If the Project itself could figure out the problems then he wouldn't have been forced to come up with an outside the box way to get units.

ALL I was trying to say was that he might not want to give away all of his secrets as others ARE listening, and they do have the power to affect his 'solution' that NONE of us may like.

Hello Admins, anybody here? I'd appreciate a feedback on this issue.
I haven't seen such problems yes, it started a few days ago and persists.
It causes my machines to run dry of GPU units, thus as a side effect the CPU cores allocated to GPUs start CPU tasks, then after a while when a few GPU units are received, they switch back to GPUs and so on. This results in constant suspending/restarting/reshuffling of CPU tasks.
