RE: Gordon, Check if

Gordon,

Check if you're long term debt is negative.

You can use BoincView to do this. Download it at

http://boincview.amanheis.de/

It's a very usefull little program.

If your E@H long term debt is negative, Boinc won't request work for it, unless all other projects (with positive debt) are out of work.

That is a long term way of honouring the resource share settings.

Once the E@H long term debt is positive again, Boinc will automatically request work for it.

The 'problem' starts when E@H downloads enough work to fill your reconnect time, which it is supposed to do according to the current rules of Boinc. Due to this boinc goes into EDF (earliest deadline first) and commits all resources to E@H to make sure it is completed by the deadline. The consequence of this is that E@H builds up a huge long term debt by hoggin your cpu for days to finish before the deadline. As a result the other projects must get the same amount of cpu time (based on your resource share) before boinc requests any further E@H work.

In theory, over time, the resource settings will be honoured, although E@H won't get work for a week, or two or three, depending on your resource settings and reconnect time.

A way to get a more even spread of work on you machine is to lower your reconnect time, but this is only feasible for people with always on internet connections. With 0.1 or 0.2 day reconnect time the scheduler only downloads 1 or 2 workunits at a time which can be easily finished before the deadline, therefore not over committing and going into EDF.

In short, short term debt determines which project get the cpu, and long term debt determines which projects get new work units

Hope this helps.

Well, this is stupid. I change to 4.45 and in long term Einstein is -112,184s, Seti is +57,570, and Climate is +54,613. It will be years be fore I can use Einstein!!!!!!!!!!!!!!!!!!!!!! sOMEBODY REALY GOOFED!

The problem is that the

The problem is that the scheduler has two main mutually exclusive objects:

1) do not let the boinc client run empty

2) honour the resource shares

In the light of the fact that the bulk of the boinc users have dialup connections, the decision was made to make objective (1) the priority in the short term, ie always have boinc running no matter what, and objective (2) the priority in the long run.

The unfortunate end result is that you will not always have the perfect mix of WU's running on your client, but in the long run the resource sharing will be honoured.

It is always difficult to find the ONE solution that will be best for all of the millions of boinc users. Maybe in future they can implement a setting in the client whereby you specify whether you have a dialup connection or a permanent connection. With the permanent connection your reconnect times can be much shorter thereby keeping a good mix of WU's on your client.

112184seconds is only 31.xx hours. That's not that big of a deal.

JM7 has actually been trying to get such a thing implemented, but David Anderson (BOINC and Seti@Homes project head) is resistant to the idea. He doesn't want to makes things more complicated.

Yes 31 hours, but everything else is goofy in Einstein's calculations, so....................we'll see. In 7 days I should get some work........right!

Perhaps. It all depends upon how the resources shares and the LTDs even themselves out.

31 hours does not equal 7 days...

And what is goofy in Einsteins calculations?

Hi Gordon,

Still the same problem for me as well. Read our disscussion at

Well It's been 3 days and my debt has only dropped 3 hours.! 7 days is more like 10 days !!!!!!!!!!!!!!!!!!!!

I Started Einstein long after Seti & Climate, but it's long term debt is 31 hrs now. I had trouble for about 10 days so there was probably another 30 hours I've made up for. The shares were set to be equal for all projects, Seti & Climate work fine, Einstein doesn't! AND THAT"S NOT GOOFY!!!!!!!!!!!!!!!!!!!!
