Well, I'd been having problems, but lately I've had plenty of Ubuntu work coming through. :)

I haven't checked, though, if some of my hosts are still having issues.

And to further clarify the answer, I believe that indicates you have enabled

https://boinc.berkeley.edu/trac/wiki/HomogeneousRedundancy

Probably with the "Coarse grain" setting?

Wiki wrote:
An "HR type" is a host classification. Currently the following HR types are defined:

0
No homogeneous redundancy (all hosts are numerically equivalent)
1
A fine-grained classification with 80 classes (4 OS and 20 CPU types).
2
A coarse-grained classification in which there are 4 classes: Windows, Linux, Mac-PPC and Mac-Intel.

So WU's are only sent to "similar" hosts, so the validation doesn't have to worry about the line ending variations. Is that correct?

Well, I've obviously been getting more work, but it's still nowhere near keeping all my cores busy. Oh well. I'll just keep plodding along slowly. :)

I've started to get a few tasks, but nowhere near as much work as I'd expect.

Yup. Really gummed up if the steadily decreasing number of WU's in progress is any indicator. I personally don't have anything left. I'll hang around for when the log-jam breaks free, but I'm forced to work towards goals elsewhere in the interim. :)

Agreed. Many other projects do actually indicate when they have no work available. As an example, here's a work request from Sztaki, a project that commonly doesn't have work available at all times of the day.

Thu 27 Aug 2015 08:10:48 AM CDT | SZTAKI Desktop Grid | update requested by user

Thu 27 Aug 2015 08:10:52 AM CDT | SZTAKI Desktop Grid | (Project has no jobs available)

But I don't know if they need to set something up in any of the server side configuration files to do so.

Well, I'm still waiting for things to get better. Way to many cores that aren't getting work here. Looking for ideas. Linux (Ubuntu 14.04) Boinc (7.4.25) Min cache (I've tried .5, 1, 2 and 5) Additional Days (I've tried 1.25, 2, 3 and 10) I've removed most other projects and have taken the 2 left and set them to NNT and even Suspended them. Still not getting work. Yet, when I enable work fetch on one of those projects (SRBase), I get tons. I've tried adjusting the project specific dcf from the current calculated value of 1.00000, to 0.10000 with no improvement either. One thing that may be unique to my world is that almost all of my hosts are hitting the project using a single firewall source address. I'm sure I've got more coming at you than your average User. :)

Just some sample work requests from a single representative host:

Thanks for the Post Krzysztof. It always helps when the management lets the volunteers know things are going on behind the curtain. :)

Correct. Overnight some of my team mates saw the message that they'd hit the limit of tasks in progress of 8 per core. They also have indicated that limit seems to have since been lifted. :)

Well, over the last 8 hours, things have slowly improved. Still have a slow trickle coming in, but also still not at a complete cache, even considering the current limit of 8 WU's per core. At least some of my hosts finally have more work on hand than cores. :)

Now, as of about 30 minutes ago, I've started receiving messages after the work request "no applications" so hopefully that means we have something being worked on server side. :)

For much of the last two days, my Linux hosts have not been receiving much work. Even though the project indicates it has work, the common response to work requests is to simply receive 0 tasks. Is there a problem with availability of work for Linux? Or even in general? I don't have many Windows hosts, but they are also not getting much work when requested.

Also, in reviewing my tasks that are "Pending" status, many of them report the matching WU is "Unsent" so there really should be work, but it seems it's not going out.
