Right, before I go the whole hog and remove / reboot / re-attach I tried reboot / reset project / update project. That produced no immediate impact but I've just gone in and set work fetch logging on.

Before I have done anything else it has logged :-

Given that this says CPDN share = 1.0 and CPDN can fetch CPU I don't understand the last line, "No project chosen for work fetch".

On the assumption that this is saying that it has had no user request for a work fetch I'll suspend WCG and Rosetta and issue such a request ...

OK, as soon as I suspended the projects it took action of its own accord :-

To me this puts the problem squarely at the server end - I do not see anything extra I can achieve from here.

Something seems to have happened at the project a few months ago.
I finally got 1 task to download on a new AMD machine, then nothing more.
Soon after, it worked perfectly for several hundred test models on the test site, but still nothing from the main site.
Upgrading an Intel machine to a newer OS caused it to stop working too.

I'm hoping that it's something about the BOINC version, and that someday I might get the inclination to have another try at getting an old BOINC version from the last computer, to put onto the others, but in the meantime, they're just gathering dust.

There has been some changes as the server status page has a different layout now and the cakebox graphics don't understand the tables for tasks in progress for different sub-projects.

---

Although it probably won't help Bryn Mawr solve the problem, I thought I'd post my observations on how fetching from CPDN has worked recently.

I have two Linux machines that request CPDN tasks on occasion. I use app_config.xml to divide the work-load as I require, and set CPDN to a lower resource share to reflect the relative workloads wanted, but whenever a necessary CPDN work fetch takes place it will try to fetch enough tasks to have one for each "CPU" BOINC has access to! From that, it would appear that the only part of the request that is of relevance to the CPDN server is the inst value!

To ensure I only get as many tasks as I want my routine is usually as follows: suspend WCG (my only other CPU task source), reduce %age of CPUs to use to match the number of CPDN tasks I want on the machine, allow CPDN to get work then update CPDN - it will fetch just enough tasks to make up the numbers - then set CPDN back to "No New Tasks" to avoid future unwanted fetches, restore the original %age of CPUs and resume WCG!

I had last observed this on 25th April when I forgot to follow my usual CPDN fetch routine on my i7-7700K (BOINC is allowed 5 "CPUs" for CPU work [there's a GPU too...] and I only run 1 CPDN task at a time, so I try for two tasks at any one time...) and when it ran out of tasks it fetched 5 new ones because I hadn't put No New Tasks on previously!

However, as there seems to be a suggestion that this might be a recent change, I have just allowed my other machine (a Ryzen 3700X, with 13 of the 16 "CPUs" allowed to BOINC (and CPDN restricted to two)) to get more work; it had 2 running and 4 waiting [already more than I really wanted, but never mind...], so I paused WCG, set CPUs to 50% and allowed CPDN to fetch - it got two tasks as I expected (and the request was as shown below...)

Fri 01 May 2020 06:43:36 BST | climateprediction.net | [work_fetch] set_request() for CPU: ninst 8 nused_total 6.00 nidle_now 2.00 fetch share 1.00 req_inst 2.00 req_secs 86400.00

Fri 01 May 2020 06:43:42 BST | climateprediction.net | Scheduler request completed: got 2 new tasks

Note that I have my cache control set to 0.45 + 0.05 days so it asked for 1 day of work, (The Ryzen usually takes just over 7 days to do one of these, so if it were paying any attention to that it wouldn't send anything!) Note also there's a GPU, but I doubt that's making any difference to the actual request.

Pursuant to Les's comment about older clients, and other things that might come into play, my Ryzen is on XUbuntu 18.04.04 with a 5.3 kernel and uses BOINC client 7.9.3 (I didn't want the version available from Gianfranco's repository when I set it up), and the Intel box is on an earlier 18.04 with client 7.14.2.

So, as I said, probably not helpful for Bryn Mawr but it is a "data point"... (and perhaps a marker to try a different client?)

Good luck - Al.

[Edited to add some (obvious?) steps I'd forgotten to list...]

Thanks for that Alan, another data point is always useful.

A separate symptom that might, at a stretch, be related? Normally I can find the results of the weekly credit run on Thursday morning and it hits BAM on Friday morning. So far this week I still cannot see these results - is there a problem?

I haven't used Gianferanco's repository recently but have 7.16.3 (home compiled) on one machine and 7.17.0 also compiled from source downloaded from Git-hub without issues. I really don't know what is going on and have run out of ideas but suspect it isn't as simple as something to do with the BOINC version. If it were, I suspect I would have seen more posts about similar problems over at the BOINC forums.

My system is using Gianfranco’s version (I’m convinced that it was showing 7.17.0 at one point but it’s 7.16.6 now) but I’ve convinced myself it has to be server side rather than the client - but then, I’m Jon Snow and I know nothing :-)

Same for me. All my machines are now up to 7.16.6 and working fine.
I think your idea about the server is right. It seems to me that I have had problems in the past getting the work going.
Just leave it attached and it will show up one of these days.

Sometimes a script crashes, or doesn't get restarted after a server reboot. I e-mailed Andy about the credit thing.

I can confirm that Gianfranco's version was using 7.17.0 at one point, I think before a decent 7.16.x was released. There was some discussion about it over on the BOINC forums.

Edit 7.17 is the testing branch indicated by the 17 being an odd number Gianfranco will use the testing branch if he thinks it is has few enough bugs to be worth using over the current official release. This means that 7.17.0 that I am using from the code latest version of the master branch will almost certainly have different bugs in it compared to the one Gianfranco was using. (I haven't found any yet but haven't done any checking other than continuing to crunch, download work and upload some zips and would be a little surprised if I could find bugs without stressing and investigating a little more deeply.)

Looks like the credit script ran in the last day. Stats should be updated on cpdn now. Not sure when the credit sites pick up that stats from cpdn.

Normally cpdn updates on Thursday morning and bam gets the data on Friday afternoon so it could be tomorrow or Tuesday depending on cut-offs.

Many thanks for sorting it.

OK, can I come back to this problem?
Having done everything I can think of including disconnecting from the project, rebooting and then reconnecting I had a last try this evening with different results that could point to a client side problem.

Firstly I suspended all projects, changed by buffers to 10+10 and turned on work fetch logging. At this point I noticed that climate prediction was subject to a resource backoff of 5159.17 seconds (this did not show up under the projects page in the resource manager) so I did a project reset. This zeroed the resource backoff so I proceeded to resume climate prediction to allow it to request work. It decided that it could request work and requested 5184000 seconds but the number of instances requested was 0, despite the number of idle cores being 12. Unsurprisingly it got what it asked for, 0 instances :-

Once again, any suggestions would be greatly appreciated.

Still not spotting what the problem is. Next time you post from the event log it may be worth first clicking on one of the Climateprediction.net messages and then at the bottom right of the event log click on "Show only this Project."

It may not help us to spot the problem but I have certainly found it easier on my ageing eyes looking for stuff without the other projects' messages there to filter out with my brain.

My sincere apologies, as the only thing that happened during that period was the work fetch I thought it might be relevant to show what was happening to the other projects as well but I’ll certainly make sure I do so in future.
