I can't seem to get GPUGRID to follow my BOINC Local Preferences. I've got the Minimum Work Buffer set to .02 days, and Max Additional Work Buffer set to .15 days, and I still get seven WU's for my 4 GPU core machines, even when there is 5-9 hours left on the 4 wu's that are running. The resource share is only 62.14%. and my app_config is set to run no more than 4 wu's at a time. Am I missing something? Hope someone can help. Thanks in advance, Rick

The estimated remaining runtime could well be incorrect (due to the recent short and long test work units all being described as 5M Gflops server side).

Any Network Usage restrictions in place?

I cant see your app_config or settings.
So, is your i7-4770's Intel HD4600 GPU being seen by Boinc (it would say in the first page of your Boinc Log file)?

If so then you can exclude the intel_GPU from being 'used' by GPUGrid (you maybe already did this).

If the intel_GPU is being seen by Boinc and you have not excluded it from the GPUGrid project, your buffer settings will mean you cache up to 4h of work, for 5 GPU's.

This might help you work out what's going on,
http://www.gpugrid.net/host_app_versions.php?hostid=157727

You can see what your different app performances are listed as for that system.
Should be going by 'Average turnaround time 0.66 days'

I thought Intel GPUs are listed a resource type that is different than NVIDIA, and so they are naturally not included within any work fetch requests to GPUGrid.

Another possibility as to the problem might be that the server-side speed estimations aren't yet calculated. It takes 10 completed task for a given host (e.g. Computer X) on a given app's (e.g. Long-Run) given plan class (e.g. Cuda 5.5) before the server knows just how fast the host can do the tasks for that host/app/planclass combination.

Until that happens, estimations of speeds are.... often wrong.

PS: <max_concurrent> in app_config.xml currently limits the number of tasks of that app that can be running at a time, but it does NOT have any effect on how much work is requested. The best way to limit the amount of tasks queued up, is to limit your work fetch buffers.

Mine are set to:
Minimum 0.05 days
Max Additional: 0.15 days

Maybe development versions of Boinc handle the Intel GPU's differently, but I have an exclude_gpu setting for my intel_gpu for GPUGrid in my cc_config file:

<options>
<exclude_gpu>
<url>http://www.gpugrid.net/</url>
<type>intel_gpu</type>
</exclude_gpu>
</options>

It's been there for a while, so I guess I thought I needed it at some stage (maybe I didn't actually need it though and just read in some forum that I needed it).

I'd be curious what happens when you take that out, and restart BOINC. If it doesn't behave correctly, maybe we can look at it further to see if a bug existed/exists.

Thanks for the feedback, Jacob, & skgiven.
BOINC is only showing recognition of my 4 nvidia processors, NOT the intel (btw, I didn't even know mt computer had an intel GPU. Is there a way to use that one too?)

I do not have any network restrictions. My wireless network is connected full time to a cable modem, with backup to a second wireless network connected to my backup DSL modem.

I'll try to answer any additional questions posted. Thanks, Rick

Just after deleting my exclude intel_gpu, and immediately got,
GPUGRID - Requesting new tasks for intel_gpu

- Obviously I wouldn’t get Intel work, but I thought it might change the scheduler causing it to cache up more work, some wonky way. Unfortunately I can't test for this because the 2 WU's I have running are 3h and 6h into a run and Boinc thinks they will take another 60h and 70h (due to the estimates).

Rick, you can download the Intel drivers and use it at Einstein.

Right skgiven, you have a resource "intel_gpu" that GPUGrid doesn't explicitly say that it doesn't support (in sched_reply_www.gpugrid.net.xml), and so BOINC asks for work for it.

When it doesn't get any work for it, it should create an incrementing resource backoff, up to a 1-day backoff. You can see that backoff in both the Project properties, as well as the work_fetch_debug log statements (if you have that flag set in cc_config.xml)

For CPU, GPUGrid explicitly says "we don't do that resource" (<no_cpu_apps>1</no_cpu_apps> in sched_reply_www.gpugrid.net.xml), and so BOINC never asks GPUGrid for CPU work. That's why the project properties can say "Project has no apps for CPU". But GPUGrid doesn't yet do that for the intel_gpu resource type.

You can keep the GPU Exclusion in place if you'd like.
But I believe BOINC is doing its job of
- periodically asking GPUGrid for work for intel_gpu (since the project may start having tasks for it, since it doesn't explicitly say that it doesn't have apps for it!)
- creating an incrementing resource backoff when it gets no work (since the project may be temporarily out of work for that resource type).

If GPUGrid wanted to save a bit of RPC bandwidth for its users that have intel_gpu resources, I think they could add a line in the sched_reply_www.gpugrid.net.xml file to do so.

Does that make sense hopefully?

PS: You can fix your estimates by closing BOINC, opening client_state.xml, finding the GPUGrid duration correction factor, and setting it to something reasonable like 1.6

Jacob,
Where can I get the Intel drivers? I'd love to get more out of my machines. Thanks in advance, Rick

I think skgiven would have to answer that one.
I'd wager, though, that you go to the Intel website, and look for graphics drivers there.

Makes sense.

Maybe I thought I needed it in place when I was also using app_config (which is an anonymous platform), didn't want my logs saturated, or was just being overcautious. I certainly put some exclusions in due to POEM's needs.

Thanks for pointing me in the right direction, skgiven. Unfortunately, I guess you can't run the Intel HD processor if you already have two dual processor video cards in your box. It cost me $60 and an 80 mile trip to the computer store to find that out. But thanks for trying to help. Regards, Rick

Don't see why that would be the situation. Did they mention why, or just charge you $60 and say it can't be done?
Have you tried to use the IHD4600 to support your primary monitor?
While I don't have two dual GPU's in any system, I do have 3 discrete GPU's in one system and I can use my iHD4000 GPU to run Einstein.

The techs just told me they could only get two of the three to work at one time (I think they spent most of their time un-doing the mess I made trying to do it myself). I only have an HDMI output for the IHD4600, and don't know how to connect it to my KVM switch. I use to be knowlageble about these things in the 1960's & 70's , when you had to rewire computers to get them to complete a task. Now technology is moving faster than this old man can keep up with, but I'll keep on trying. Thanks for the nuggets of info. I'll keep following the trail, until I figure this out. Regards, Rick

Skgiven,
I can't thank you enough for the help getting my IHD to work. Your suggestion to use the IHD as my primary monitor did the trick, and I'm now crunching Einstein@home om it! Now more NVIDIA GPU time for your GPUGRID. Now on to my other two I7 machine and try to getr them to work too. Thanks again, Rick

I believe you need a load on the intel VGA (or DVI) port. One way is to plug a monitor in. Another way would be to use a dummy vga plug. The way most bios's are set up is if they don't detect a device on the iGPU and you have another graphics card they simply disable the iGPU

Also if you get the intel GPU driver through windows update its not usable for crunching. You need to get the 'full' package from the intel download centre.

Probably a bit late but maybe it will help someone else.

Thanks for the input MarkJ. Luckly, I installed the correct (full) driver directly from Intel's site. I was using the Intel port for my monitor (that was the only way I could get the Intel GPU to work), but maybe I need the dummy plug for drive 0 on my GTX690? I've ordered 3 VGA Dummy Pluggs (1 for eacj of my i7 machines), and hope to receive them by next weekend. It would be great, if that's all that's needed. Thanks again, Rick

i have 4 machines running with no monitors and no dummy plugs, 3 of the machine have 2 nvidia each and 1 has 1 amd card. they all work fine. i think only the integrated gpu (intel) needs dummy plug.

XtremeSystems.org - #1 Team in GPUGrid

I have my monitor on the iHD4000, and don't use a dummy plug for the 3 discrete GPU's in the same system (660Ti, 660, HD5850). I can still use the iHD4000 at Einstein and the 3 discrete cards to crunch. The only issue is that I cannot launch the NVidia control panel (but I don't really need to anyway - things are working well enough as is).
