Message 100941 - Posted: 16 Nov 2016 | 9:55:21 UTC

Hi,

I've been trying to get my computer to run AP27 GPU tasks, but they only run for a few seconds then go into Scheduler Wait state for a while before the task reinitialises and starts again from zero percent done. This repeats forever and I end up having to abort the tasks. From what I can gather on other BOINC sites, Scheduler Wait means it's waiting for more memory, though I can't find any exact matches on the forum here.

My GPU is an AMD/ATI Radeon (Turks) HD6670 with 2Gb RAM on board. BOINC reports it with CAL version 1.4.1848, 2048MB, 1970MB available, 1632GFlops peak, driver version 1800.11, OpenCL 1.2 AMD-APP.

Other PrimeGrid GPU tasks run fine, it only seems to be AP27 which is having this problem. I know it says AP27 tasks need 1.5Gb+ of VRAM, but as mine has more than this I thought it might be ok. I've tried this in the past and given up, but thought I'd revisit it with the Wallis is Born Challenge coming up, I was hoping it might have been a bug which has been fixed by now, but apparently not. Is there a setting I'm missing somewhere to get this working, or is the HD6670 just a non-starter?

Thanks,
Gary.

Message 100966 - Posted: 16 Nov 2016 | 19:08:08 UTC

In the BOINC Manager, on the Disk and Memory tab, have a look at the memory section. Mine, for example, says BOINC can use 50% of the RAM if the computer is in use and 90% if it's not in use. As my computers all have at least 12GB of RAM, this never affects me. But it could explain what's happening to you. If your settings are similar, I'd raise the percentage of memory available to BOINC while your computer is in use. I'd also look at the Computing tab and check the "When to Suspend" settings. I've got everything in there unchecked, so I don't think my system ever hits the "in use" state.

I'm not sure this will fix your problem, but it's where I'd start looking.

Message 100990 - Posted: 17 Nov 2016 | 0:17:42 UTC - in response to Message 100966.

Thanks for the suggestions JimB. My memory usage options are set at 95% when in use and 99% when idle (I don't tend to do much else with this particular computer, so just let it sit doing BOINC work most of the time and have most of the memory & cpu to itself). The BOINC log reports 3.86Gb of physical memory available (non-GPU) and 1.91Gb virtual. Plenty of disk space too (48.99Gb free). I've ticked the boxes to run cpu and gpu tasks while the computer is in use as well, so it shouldn't be suspending them unless non-BOINC work exceeds 80%, which it occasionally does when background admin tasks are running, but then ALL the tasks get suspended, not just one. I've even tried manually suspending all other tasks so there's only the AP27 one running, but it still does the same thing. I did notice that if I clicked on Properties for the task while it was in Scheduler Wait state, the virtual memory size and working set size were both only a few hundred megabytes each, but I don't know if that relates to the GPU's VRAM or just normal computer RAM, or even if that's relevant. All I can think of is that the task wants to allocate more than the 1.9Gb available, but I can't find any messages to support this or say anything else which might give me a clue what's up.

Message 100991 - Posted: 17 Nov 2016 | 5:13:19 UTC - in response to Message 100990.

In your BOINC Manager, if you click on Options / Event Log options (might be under some other menu, I think it's moved around between sections over time), there are three debug flags that could be interesting to look at. They are: cpu_sched, cpu_sched_debug and cpu_sched_status. I would start with only cpu_sched checked and see if that gives you enough new information. cpu_sched_status looks like it outputs the current state at intervals and cpu_sched_debug is maybe too low-level to be of use here.

Anyway, with one or more of those turned on in optins, you can see what your BOINC log (Tools / Event Log) is saying when you're seeing this scheduler behavior. Ideally it should tell you why it's suspending the job. You can turn those options off again if/when you get useful information. You don't need to restart BOINC or anything - they take effect immediately when you click OK in the options dialog.

I don't seem to have those options under any of the BOINC Manager menus, but I managed to turn them on via my cc_config.xml file and there's a menu option to reread the config file(s), so fairly easy to turn them on & off that way. I didn't get much from it with just cpu_sched, so added the others you mentioned, and a couple more which looked interesting... there's a bit more in the log now, but I'm still not seeing what the problem is :

The Einstein tasks mentioned are all suspended, as I suspended the project so that there's only my one PrimeGrid AP27 task active. I don't have any other tasks on that computer at the moment.

Does any of this look unusual to you perhaps?

Also forgot to mention, this is on BOINC Client version 7.2.42 for x86_64-pc-linux-gnu on an AMD Athlon dual core 64-bit cpu with AMD Radeon HD6670 gpu coprocessor.

Does any of this look unusual to you perhaps?

This one.

temporary_exit is an unusual state (not an error, not a normal exit), may be author of the app could help you to find what the app dislikes.

Thanks, yes, that does look a little unusual! Ah well, guess my gpu won't be contributing to the current challenge then, not to worry, I'll clock up a few cpu tasks instead. It would be nice to know what's wrong at some point though. Will wait and see if any app authors respond.
Cheers!

Thu 17 Nov 2016 09:25:15 GMT | PrimeGrid | [task] Process for ap27_155075_0 exited, status 0, task state 1 Thu 17 Nov 2016 09:25:15 GMT | PrimeGrid | [task] task called temporary_exit(60.000000) Thu 17 Nov 2016 09:25:15 GMT | PrimeGrid | [task] task_state=UNINITIALIZED for ap27_155075_0 from temporary exit

temporary_exit is an unusual state (not an error, not a normal exit), may be author of the app could help you to find what the app dislikes.


The boinc_temporary_exit() state is entered if the GPU is out-of-memory. Your GPU is reported to have 2048MB of VRAM, and the AP27 app requires less than 1500MB. So BOINC manager restarts the task, hoping that whatever was using up the memory has stopped, but in your case it never seems to succeed.

So either it's the case that something is running that is consuming VRAM (could be your OS/windowing system/video driver), which you might be able to reduce, OR BOINC is reporting more memory than is actually present in your card, either due to a BOINC bug, video driver bug, or OpenCL driver bug. From a brief look, most of the "HD 6570/6670/7570/7670 series" have only 512 or 1024MB, although some have 2048MB. If you're sure you have 2GB of VRAM, I'd try upgrading to the latest driver from AMD.

Cheers

Thanks for the info Iain, I'll have a look into this. I remember having a nightmare getting it working at all with various Linux drivers and thought I had the right AMD one, but maybe not. Will have a check tomorrow with a fresh head and cup of coffee! Cheers. :-)
