I have 5 computers that have been requesting about 120 WUs just sitting idle waiting for hours and nothing. Status just keeps changing to Deferred an hour over and over. Is the DL server broken???

Other projects take seconds to a few minutes to begin DLs.

A few WUs just came down and reminded me that CP does not respect the presence of GPU WUs. CP wants to run multi-week WUs using every CPU thread regardless of whether GPU WUs are running. I have to include <ncpus>22</ncpus> in the cc_config and abort the excess WUs. Makes no sense that such a long WU would insist on time-slicing with itself.

I'm not sure what the download problem is. One of my PCs just requested and downloaded a task without any errors listed or retries.

We can't see your PCs on the website as they are hidden. Have these PCs previously downloaded and successfully crunched work units? What are the messages in the boinc manager message log when it sends a request to cpdn for work?

Problem was that the only WUs are WAH2 and they only come in Windows. It was the Linux computers that didn't get any work. Shame they don't support Linux any more because I can do over ten times as much Linux work as Windows. With the end of support for Win7 coming in a few months I'll go all Linux.

If you read in the Linux board there is clearly still support for Linux, just not on a huge scale yet as Linux users are by and large in the minority vs. Windows and because I think they're trying to get a new project into the pipeline for Linux only that will be larger in requirements than the current one for Windows.

I also don't find Linux crunches any faster than windows. The only project that really shined for that was WCG for me. Having a Linux /boot fill up to capacity and not allowing me to install or remove updates at all has really soured my, all be it, limited experience with it. On Windows 10 with a 75 day uptime, so I must be doing something right :)

Why would any BOINC project write anything in /boot on a Linux machine? How have you set up your Linux machine to run BOINC? I gave mine a partition of its own so any bugs or malware is confined. (I have not experienced any.)

This is all I have in /boot:

/dev/sdb2 499656 77204 396240 17% /boot

I have all my BOINC stuff in a partition of its own:

/dev/sdb7 24059020 4089736 18740484 18% /home/boinc

and that is mostly Rosetta and WCG because I no longer get any CPDN work units.

Boinc did not write anything to boot.
However here's the content of my /boot directory, which is at capacity. Removing all of the extra colonels just adds them back when I attempt

sudo apt-get -f install
So at this point I can crunch on it all day, which isn't a bad thing, but can't actually do anything with the OS because the package manager has no more room.

My apologies for being so new at all of this but what's the command to actually check the size of the boot partition? Regardless, here is the content of mine.
Quite a few files in here - you would think Ubuntu would automatically only leave the current colonel plus perhaps one more. It doesn't appear to. Also this is badly formatted. Apologies.

.

Just looked in my boot partition. It has a few more files than yours but none written by BOINC. Also none of yours are written by BOINC. Here is a link with regards to removing old kernels. I shall be clearing mine out again soon. It still has the ones from xubuntu 18.10 as well as the 5.x.x from 19.04

Great. Look forward to trying it.

Sounds like what happens on Rosetta if one does not have enough RAM to sate the beast.

I have ten times as many computers running Linux as Win7.
GPU projects definitely run faster on Linux. Don't know about CPU projects.

In the days when CPDN produced tasks that ran on all three platforms, (Windows, Mac and Linux) the difference was marginal but I can't remember which was faster.

Now because all tasks are single platform it is impossible to say. Many Linux advocates claim it should be faster because of less bloatware but I would hesitate to make such claims myself without some hard evidence.
