I seem to have stopped running GPUGRID jobs for the last ~12 days, though other GPU BOINC projects run jobs and there seems enough jobs in the queue:

Another odd thing is my project stats show 1 and only 1 task (from Jan 2016) but nothing credited since, but that's not correct.

Any hints would be appreciated.

Exit BOINC manager with stopping scientific applications, and then update your NVidia driver.

The installed driver is latest Nvidia long lived (375.66)

Should it be necessary to move to short lived branch (381.22)?

Are there other appropriate cc_config.xml debug flags that can be set to help determine why? I'm not seeing the reason in the log so far.

Requests for new tasks always result in the following even when >2000 tasks available:

Thanks for any tips, I'd like to keep contributing to the project.

Same problem I had....kept deferring communication..no tasks even though available.

I've enable other debug flags but am unable to determine why no work units received since early July.

I've enjoyed contributing to this project, particularly seeing the resultant publications, and would like to continue. Of course there is WCG, but I'd like to continue with GPUGrid as well.

Others things I've checked:

Updated client and manager to boinc-client-7.6.33-2.2.x86_64 (Suse Tumbleweed repos)

Ensured 32 bit libs needed were installed
http://boinc.berkeley.edu/wiki/Installing_on_Linux

Turned on additional debugging in /var/lib/boinc/cc_config.xml

Verified client_state.xml values look okay
https://boinc.berkeley.edu/dev/forum_thread.php?id=10936

Checked client logs in ~/.BOINC

Any other suggestions for how to troubleshoot would be appreciated.

Have you tried the 384.47 Linux driver?

Hi Jacob,

Unfortunately, updating the Nvidia driver to 384.47 didn't improve things.

Cheers,
Pete

It seems to be an issue with the server software. Might be impossible to troubleshoot further, without a GPUGRID dev/admin to look into it. Sorry.

Perhaps the server put your host to the blacklist forever. To fix this you should try to force the BOINC manager to request a new host ID for your host. You can do it by stopping the BOINC manager, editing the client_state.xml, searching for <hostid>260678</hostid>, and replace the number to the number of a previous host of yours (or a random number, if you don't have an older host), saving the client_state.xml, and restaring the BOINC manager. Maybe it won't work for the first time, so you might try this a couple of times.

Thanks for the suggestion on changing hostid in client_state.xml - and for the tip on stopping boinc manager (and verifying with ps) as otherwise the value reverts.

I replaced the old hostid (260678) and re-used an older hostid (94323), which has propagated up and is reflected as the currently active host at

http://www.gpugrid.net/hosts_user.php?sort=rpc_time&rev=0&show_all=1&userid=63993

Still no new tasks are received.

Is the matter now perhaps one of scheduling priorities with other projects? When suspending all other projects and updating GPUGRID the log is shows

If you're asking how to read the work_fetch_debug, here goes. Pay attention.

A "work fetch iteration" has happened. This usually happens every few seconds, but can also happen when the user has changed something like Suspend/Resume, No-New-Work, Update-click, etc.

Sun 23 Jul 2017 11:48:15 AM EDT | | [work_fetch] target work buffer: 17280.00 + 25920.00 sec

Your current buffer settings are: Maintain at least 17280 seconds (0.2 days) of work for all resources, and when asking for work optionally ask for an additional 25920 seconds (0.3 days).

- "can request work" means that you are not actively setting suspend or no-new-tasks.
- In this case, there is not a "project backoff" (which a project could request after you contact it).

- "shortfall" is 345600 seconds. This is (17280 + 25920) * 8 CPUs. Basically, all your CPUs don't have any work. In fact, "nidle" (number idle), is 8, meaning all 8 cpu resources are currently idle. WE NEED CPU WORK!

- "shortfall" is 43200 seconds. This is (17280 * 25920) * 1 NVIDIA GPU. "nidle" is 1. WE NEED GPU WORK!
- GPUGRID says "project is backed off (resource backoff: 261.47, inc 1200.00)" ... This is a RESOURCE BACKOFF. It means, since you didn't get work for this resource type (NVIDIA GPU) last time you asked, then your BOINC Client backs off (stops asking) this project for work for this resource type... for a time interval (261.47 seconds remaining) that can exponentially increment (1200 on next increment) up to 24 hours.
- Note: I believe clicking "Update" will clear any project backoffs or resouce backoffs.

No "request for work" for you. :) work_fetch_debug correctly decided: Do not ask GPUGrid for work.

Sorry this doesn't help solve your problem. But now you know a bit about reading work_fetch_debug.

Thanks Jacob!

I've been reading posts and the wiki, piecing together the responses and their meaning, but your post was one of the clearest I've seen.

I suspended other projects today while debugging (which is maybe the exact wrong thing to do as the priority scheduler may then never escalate GPUGRID?) thus the no CPU or GPU tasks running.

The update button is being used but does not clear any project backoffs or resouce backoffs - though again perhaps this is related to scheduler and resource share tracking?

Would temporarily detaching from all other projects eliminate scheduling contention possible reasons for the backoff, or is that not a correct route to pursue? (The odd thing though is no changes were made in early July, when tasks stopped being received, but of course there maybe be more than one issue in the stack being resolved.)

Thank you everyone for the suggestions.

Clicking "Update", while project GPUGrid is highlighted, should clear its backoffs.

If you don't mind losing in-progress work, or stats on your host, or setting up your BOINC environment again ..... then you might consider uninstalling BOINC, removing your data folder, then reinstalling BOINC.

As I said before, I think there must be a server-side bug that is preventing the server-side-scheduler from sending work to Linux clients. Unfortunately, GPUGrid admins haven't been offering much help to us peon users as of late.

I have also been having trouble getting tasks for my Win7 machine -- keep getting "no tasks available" when server status shows that plenty are available. This has been going on for several weeks. Now and then I will actually get a task -- but usually not.

Also been happening with my XP machine -- but not as often. (No remarks about XP plese . . .)

So long GPUGrid...

I've enjoyed contributing to this project (off and on since 2010) but the amount of debug time, just to get tasks, is far too high - and the periods of no tasks far to long. Other BOINC projects run fine, with no feeder issues and rare server issues.

Several years ago I ran Folding at Home on a PS3, but never checked out their Linux client. A quick visit to their site and minutes later I'm crunching long runs on my GPU. It was so easy.

I might give GPUGrid another shot in the future, but for now I'm glad to be able to contribute once again to another GPU cancer research project.

I'm glad there are many users who are able to contribute to GPUGrid, but happy I decided to look again at F@H.

Thanks to everyone who took the time to answer my questions.

Cheers,

Thanks as well for crunching for us. Sorry we can't help you right now but we are aware of the problems with the current implementation. Hopefully in the near future we will find time to improve on it.

I just wished F@H was in Boinc environment.

Hi,
Having the exact same problem here. Running a windows 10 laptop with a GTX 670M. Haven't got new tasks from this project for weeks despite 1000 + being available. All other projects crunch on the GPU just fine. I'm glad I'm not the only one having this problem. I'm getting no new tasks, either for CPU or GPU, from this project. Haven't changed anything on the machine. I must say this is pretty frustrating - I think it may be time to look elsewhere for me, too, until this gets resolved.
Here's hoping it's soon!
