* New: Added ability for a project to be specified as a "Backup Project" by setting its resource share to 0

Projects require at least Changeset 20315.
Projects supporting this:

- AQUA
- ClimatePrediction.Net (since June 4, 2010)
- Collatz Conjecture
- DNETC
- Einstein@Home (since June 8, 2010)
- Enigma@Home

On my XP windows machine with an NVIDIA GPU, BOINC continually requests GPU WUs from projects that don't support a GPU (such as climateprediction.net and world community gird) and therefore gets no WUs. After a few days of doing this, it will finally download some non-GPU WUs. I upgraded from version 6.10.18 to the new release 6.10.56 hoping that would fix the problem, but it didn't. So ... what to do ...

That's not a bug, that's a feature (works as designed:-)

If it didn't so earlier, BOINC had its reasons (debt issues,...).

Nothing, all is fine (in this respect).

* New: Added ability for a project to be specified as a "Backup Project" by setting its resource share to 0

It would be interesting to get a little description on the behavior provided for Backup Projects, covering such points as:

1. When the non backup projects have work, is any backup work prefetched? If so, how is it handled as it approaches deadline?

2. If not, then how far below desired must non backup work fall before any backup work is fetched? To zero work?, to first empty task slot?, to some percentage of desired? ...

3. If non backup projects work down to zero on local host, how much backup work is fetched? The full specified desired queue? some percentage of that? Only a task to fill a currently empty slot? something else?

4. Once desired work is again available, how is backup work in local inventory handled? For tasks already started? For tasks not started (if it does that)?

I'm just generally interested, the specific questions are just meant to stimulate response--not necessarily the right questions to get a general description.

Assuming the behavior turns out to be civilized, I like this addition, conceptually. Keeping everyone happy and believing it civilized is probably as nearly impossible as are other scheduler goals. Hence the questions.

If a project does not support GPUs, then why waste time requesting GPU work???

and therefore gets no WUs.

1. When the non backup projects have work, is any backup work prefetched? If so, how is it handled as it approaches deadline?

No. BOINC will only download work from that back-up project when either of the other projects do not have work or are temporarily out of the running.

2. If not, then how far below desired must non backup work fall before any backup work is fetched? To zero work?, to first empty task slot?, to some percentage of desired? ...

When BOINC is out of work for your normal projects, or about to run out of work, it'll fetch work from the back-up project.

3. If non backup projects work down to zero on local host, how much backup work is fetched? The full specified desired queue? some percentage of that? Only a task to fill a currently empty slot? something else?

I don't know. Am running that as a test with Seti down and Enigma as back-up. But Enigma still had work in queue, so I'll have to wait before I can answer that. Anyone else who knows?

But I think it's only one task per CPU.

4. Once desired work is again available, how is backup work in local inventory handled? For tasks already started? For tasks not started (if it does that)?

They'll just run every once in a while and before their deadline.

How should the client know if the project might have introduced a GPU application since the last request if it doesn't ask?

BOINC doesn't know which projects have GPU work and which don't.
A project that has no GPU app today may have one tomorrow. If you want BOINC to use the GPU on that project, it'll fetch work automatically, when it next contacts that project and sees they finally have a GPU app.

By the way, if you don't hammer the Update button, the back-off for the GPU scheduler polling projects will become longer and longer, eventually it'll only ask for GPU work from the projects once every 24 hours.

I thought wrong. :-)

Full 5 days worth of work.

Grumble. I liked your guess better than I like the truth. Nevertheless it is good to know the truth. Thanks.

Is five days your CI or AW setting?

For a backup project, shouldn't we ask for it to be CI only? In fact, I thought that was what David said when he checked in the change. I'll have to go back through the notes.

Edit - [trac]changeset:20286[/trac]: no, he didn't. Memory playing tricks again.

Join the club. :-)

CI = 0
AD = 5.1

Anyway, I sent it to BOINC Alpha as well. I'd expect 1 task per CPU from the back-up project, not the full amount of additional days... especially as they don't run anyway.

Message 33155 - Posted: 31 May 2010, 9:25:21 UTC

Dear Friends:

I installed BOINC 6.10.56 on my Quad-CPU HP workstation with an NVIDIA GeFORCE 8800GTS GPU. OS is Windows 7-64 bits, NVIDIA driver version is the latest, 197.45.

Unfortunately, when requesting new tasks for GPU, Milkyway@home replies:
"Message from server: No work sent, Your computer has no ATI GPU,
Your NVIDIA GPU lacks the needed compute capability (1.3, required for double precision math"

I don't see why and where there is a problem: my GPU is listed as CUDA 3000-compatible.

Please help.

Not a BOINC problem, but a Milkyway requirement. They only allow GPUs which can do double precision floating point math to do their work. Your GPU apparently can't do this.

I think only the GTX 2xx and 4xx versions can do double precision, as well as the Tesla.

I keep getting warnings about "Suspending computation - CPU usage too high" and "Resuming computation", which appeared only since version 6.10.54.

I tought it was part of the problems with .54, but they reappeared when I installed .56

Is that normal, due to new features?

Just wondering what with 6.10.57 that corrects a longstanding elapsed time loss bug all through 6.10.56 [back at least to 6.6.38], why there is a Windows and Mac version (confirmed to fix this) but not a Linux. Opposed to popular believe, total system hangs and power outs do occur for this platform too as frequent as they occur for W7... same powergrid here.

See Suspending computation - CPU usage too high for more information.
One extra detail I believe I've seen, which is actually quite annoying.

As Einstein (the second most popular BOINC project, I believe) does not yet use web site code which gives you the option to set this throttling function as you like, or disable it, you have to do so from SETI or another project which does.

This point is covered in the link Ageless provided. The nasty additional surprise for me was that if I subsequently changed a preference using the Einstein web page (in my case I raised a parameter governing my work queue size), then when my host updated preferences from the Einstein site (as it must, since the freshness date is now newer), the undesired (to me) 25% returned. In other words, setting 0 for this parameter at SETI does not currently propagate to Einstein (and most likely any other project running too old a version).

So, despite the fact I've embraced the new "backup project" capability to lower SETI from 4% to backup, I must do any and all general preferences adjustments at SETI, and not at Einstein, as I wish not to lose productivity and wish not to have a message log full of start/stop messages from this source. Fortunately when times are good I seldom change general preferences.
