Posted 22 Nov 2015 by Claggy
Hello Crunchers,

This is my first post on this forum, despite crunching for more than 6 years now!

I would like to use my Intel iGPU (HD4600 on i5-4670) in addition to my NVIDIA GTX 660. My preference allows Intel GPU to work. I enabled both in my BIOS, download latest driver available and BOINC seems to detect both. I don't have a dummy plug nor a monitor connect to my motherboard. Even with everything I've done and read on forums, I can't get Intel GPU tasks. So, right now, I really don't know what else to do.

Here are the part of my log that might be interesting for this particular problem :

Can anyone explain me why I don't get jobs when requesting them? More important, how can I resolve this problem?

Thanks for your help and keep crunching!

That was reported at Albert, there was no response, this one works:

Your Intel GPU doesn't get work because:

a) it's too new for the plan class where driver versions don't matter. (Needs to be a 'HD Graphics [123]|HD Graphics 40**' Intel GPU)
b) for the plan class for your GPU, the driver version is too new.
c) for the beta plan class, you don't have it selected in your project preferences.

Posted 10 Nov 2015 by Claggy
I've tried entering a password in the gui_rpc_auth.cfg file, but still get the Authorization failure: -155 message.

Did you restart Boinc or the Pi 2?

You need to supply the gui_rpc_auth password, or navigate to the directory boinc is installed in:

http://boinc.berkeley.edu/wiki/Controlling_BOINC_remotely

http://boinc.berkeley.edu/wiki/Boinccmd_tool

and maybe allow access in the remote_hosts.cfg

7) Message boards : Problems and Bug Reports : gpu task taking 10 times as long. Stuck at 67% ? Should I abort? (Message 146873)
Posted 8 Nov 2015 by Claggy
The cure is to stop and restart BOINC. Suspending the task does not work if you have the pref setting 'keep tasks in memory when suspended' set.

Why? GPU tasks are Always removed from memory when suspended. The 'keep tasks in memory when suspended' setting relates to CPU tasks only.

I was commenting about observed behaviour with AMD GPUs. I didn't ever notice the particular problem of very slow running tasks with nvidia GPUs.

All GPU apps, be they Nvidia, AMD or Intel should exit memory when suspended (assuming they're not running a buggy boinc api)

On several occasions and over different machines, when this problem happened I would 'suspend' the entire cache except for just the running tasks. I did this to prevent any 'unstarted' task from attempting to start when I suspended the 'slow running' tasks. My recollection is that all concurrently running GPU tasks were affected and often had elapsed times of 30-40 hours or more instead of the much smaller time it should have been. I would suspend those tasks for at least 10-15 seconds before allowing them to restart again. Once restarted, they would NOT run any faster and would not reset to an earlier time or % completed state.

If I stopped and restarted BOINC instead of just suspending/restarting, or if I just rebooted the machine as I often did as a precaution anyway, the rate of progress would immediately return to normal. Tasks would restart from previous checkpoints, with the progress and elapsed time noticeably less than before but with the time still severely inflated. For example, the elapsed time might reduce by an hour or two when restarted, sometimes more. This behaviour was happening on at least 5 different machines at intervals of around 4-8 weeks - so highly annoying, if it wasn't noticed for a few days. At the time, all affected machines were running AMD GPUs on 32bit Linux.

These days, all my machines run 64bit Linux with current drivers and the particular problem doesn't seem to happen any more. Because the problem couldn't be resolved by suspending and restarting the tasks and because I had the setting to keep tasks in memory when suspended, I assumed that this was perhaps related. I didn't bother to run for several weeks with this setting turned off and then wait for another example to show up so I could see if suspending the task might then work.

I chose to add the functionality to my control script to monitor hosts very regularly (as low as every 3 hours) and log any hosts that don't meet the appropriate task fetch and task return rates, amongst other things. the idea was to catch performance issues as early as possible. If a possible problem is flagged, it gets checked manually and the machine gets rebooted if the problem is real. Unfortunately, the problem has gone away, now that I'm really looking for it :-). There are a small number of 'false positives' from time to time so the system should work if the real problem comes back.

So, yes, I shouldn't imply that the 'keep tasks in memory' setting was preventing 'suspending' from clearing the problem. That was just an untested assumption.


The difference between just suspending tasks, and restarting Boinc/the OS, is that Boinc/OS is possibly still using the same core/thread for feeding the app,
restarting Boinc/OS, most likely will switch which core/thread is being used for the feeding.

Raistmer has done a lot of experimentation because the same problem on the Seti OpenCL apps on Windows, His current apps bind to a different CPU core for each instance.

Why? GPU tasks are Always removed from memory when suspended. The 'keep tasks in memory when suspended' setting relates to CPU tasks only.

Since Boinc 6.6.37 after i reported a Boinc race problem:

- client: when suspending a GPU job, always remove it from memory, even if it hasn't checkpointed. Otherwise we'll typically run another GPU job right away, and it will bomb out or revert to CPU mode because it can't allocate video RAM

http://boinc.berkeley.edu/dev/forum_thread.php?id=2518&sort_style=6&start=75

There are occasions when GPU tasks aren't removed from memory, during benchmarks, when computation should stop for the duration of the benchmark, and during 'Suspend work if CPU usage is above x %' when it is left in memory.

but it doesn't show any checking of a CPU work plan class. It should show something like

I'm also having difficultly getting work for my T5500 Linux host, x86_64 this time.

With all the BRP apps selected in project preferences (default venue), there is no mention of Gamma-ray pulsar search #4/FGRP4-SSE2 or Gravitational Wave search S6Bucket Follow-up #2 or #3:

10) Message boards : Cruncher's Corner : Building Boinc for Einstein@Home and the Raspberry Pi 2 (Message 142397)
Posted 6 Aug 2015 by Claggy
I've reported the problem of the Boinc client not displaying the Arm CPU model, it's been fixed, and backported into the 7.2, 7.4. and 7.6 heads,

If you want the fix applied to a self compiled client you should compile Boinc from the 7.2, 7.4 or 7.6 head and not a tagged client_release, use one of the following:

git checkout client_release/7/7.2

git checkout client_release/7/7.4

git checkout client_release/7/7.6

11) Message boards : Cruncher's Corner : Using Intel iGPU on Windows 10, anyone have advice? (Message 142307)
Posted 2 Aug 2015 by Claggy
I have enabled Intel Graphics in the project preferences page.

The event log just says:
01/08/2015 17:37:58 | Einstein@Home | Not requesting tasks: don't need (CPU: ; NVIDIA GPU: job cache full)

Boinc isn't detecting the Intel GPU, you'll have to either connect a monitor, or extend the desktop onto it before Boinc will be able to detect it.

host 11853017

Then you can worry about drivers.

What does the Boinc startup in the Event Log say? It could be that you're not allocating enough memory to run four tasks, mine is set to 75% when in use, 90% when not in use,
My Boinc startup, I'm presently running four Setiathome tasks, when is suspend them all, and grab four Einstein tasks, all four start:

So how do I fix the problem? As I say, there is plenty of free disk drive available yet the error message says none is available. I have not changed anything since installing the program.
Lawrence

You're set disk_min_free_gb as 50.00GB, you only have 48.91GB free, Set the 'Disk: leave free at least x GB' to a lower value, say 5GB, instead of 50GB, in either the Web Computing Preferences, or locally in Boinc Manager if you're using local computing preferences (these override the web computing preferences).

You can try setting <skip_cpu_benchmarks>1</skip_cpu_benchmarks> in a cc_config.xml

http://boinc.berkeley.edu/wiki/Client_configuration

<skip_cpu_benchmarks>0|1</skip_cpu_benchmarks>This will disable the periodic benchmark testing as well as block the 'run CPU benchmarks' from the manager menu.

I have just noticed after getting the AMD drivers updated this in the boinc logs, and clinfo reports the Intel GPU.

26-Apr-2015 19:02:57 [---] OpenCL CPU: Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz (OpenCL driver vendor: Advanced Micro Devices, Inc., driver version 1642.5 (sse2,avx), device version OpenCL 1.2 AMD-APP (1642.5))


So am I right in saying AMD have just released a OpenCL driver for Intel GPU for linux?


No, that says the Cental Processing Unit, ie the CPU has OpenCL support via the AMD drivers, no mention of an Intel GPU there.
