1) Message boards : Number crunching : AP task (NV) hitting 2GB memory limit and resetting over and over again (Message 1698223)
Posted 1 day ago by Harri Liljeroos
The problematic WU finished without a major hitch with the new app, and so have the rest of AP WUs since that.

Only thing to point out is that the app seems from time to time use high amount of CPU which causes some lag on computer. For example the clock app stops maybe for 5 seconds before catching up again. And when running two APs at the same time the apps seem to sync that high CPU usage making it seem even worse.

Maybe removing the -hp parameter from cmd-line or allowing only one AP at a time in app_config could improve the user experience.

I just installed Lunatics 0.43a, let's see what happens.

A few comments for your questions:
- I am running 3 WUs at a time on the 970. Two were APs and one Einstein BRP6.
- Two CPU cores were free to feed the GPU
- Intel GPU was not used
- 6 WUs running on CPU, 2 MBs and 4 CPDN PNWs

Tahnk you for everybody helping.

Hi
here's the task http://setiathome.berkeley.edu/workunit.php?wuid=1835824773

It is running on my GTX970 and the CPU usage and memory usage are very high. The CPU usage is about 95% and memory usage goes up to 2 GB and then the application just restarts itself. The application is Lunatics AP7_win_x86_SSE2_OpenCL_NV_r2721.exe with parameters:
-unroll 18 -oclFFT_plan 256 16 256 -use_sleep -ffa_block 16384 -ffa_block_fetch 8192 -hp -tune 1 64 8 1 -tune 2 64 8 1


Is there something I could try before aborting it?

make a -right-klick- on the messages, then you can select the project you would like to see.

and you can also make a -right-klick on the hm "messages-top-bar" to add or remove columns you wanna see.


Yes, I can select the project which messages I want to see, but I would still like too see the Project column for easier operation. Right clicking the titles in Messages tab shows "Show or hide columns" but it is greyed and has no effect.

Posted 5 Jun 2015 by Harri Liljeroos
I just installed the 64 bit version 1.66 on a Win 7 laptop. The problem is that the Messages tab does not show the Project column for the Messages. So it is difficult to understand from which project each message is coming from. There seems to be no selection options in the settings which columns to show for Messages tab. Other tabs (Projects, Tasks etc.) have this possibility but not for Messages.

I use BoincTasks on other computers also, same version even, and they all show the Projects column in Messages tab. They have originally been installed from older version and just updated to this 1.66 later on.

Has anybody seen this kind of behavior? And how to fix it?
7) Message boards : Number crunching : v7 7.00 not getting CPU time; Recent Estimated Credit (Message 1663157)
Posted 9 Apr 2015 by Harri Liljeroos
I've come to similar conclusions by trying to adjust the project shares between Seti and Einstein so that they would get about same RAC. But Seti's inability to produce constant flow of work has made it difficult to track. Currently Einstein's share is 12 and Seti's 50. That was giving almost what I wanted until the current server problems here hit us.

To make it more interesting, I'm running LHC with a share of 150. This keeps the CPU constantly busy with LHC work (when available) and as LHC don't have GPU application, Seti and Einstein use my GTX970 totally. 3 WUs at a time for both Einstein and Seti. Einstein is currently allowed to use the CPU as well but LHC dominates there and all Einstein CPU WUs (only very few at a time) run basically only at EDF mode usually starting just about 20 hours before the deadline.

Run time 17,018.30; CPU time 13,856.16. It ran during the night so I wasn't monitoring the system. Anyway it was running 8 CPU tasks and 2 CUDA tasks at the same time, so no free CPU was available.

Now waiting for wingman to finish his.

I think all this part in quota should be removed


Thanks, I may try that later. I'll wait and see if the scheduler fix has any affect for this. As we are not splitting any AstroPulse at the moment, it is hard to tell.

try to decieve BOINC telling it that Intel GPU AP is CPU app.
SETI BOINC server has no intel GPU app so we need same trick as when there was no ATi support from BOINC..


How would I do that? By removing this section from the app_info.xml?

<avg_ncpus>0.04</avg_ncpus> <max_ncpus>0.2</max_ncpus> <plan_class>opencl_intel_100</plan_class> <cmdline></cmdline> <coproc> <type>intel_gpu</type> <count>1</count> </coproc>


Or just by removing the <plan_class> section?

I briefly looked at SongBird's app_info and noticed that you don't have AstroPulse application for your Cuda card. Your app_info seems to be similar than mine for the AstroPulse Intel OpenCL (mine is from aistub file) except for the last <app_version> section. I did add that part to my app_info.xml to see if that makes any difference. Well, it didn't. Unfortunately I can not get any AstroPulse WUs for the Intel HDGraphics. Maybe this is because I have the Cuda application for AstroPulse running as well? This all I get as a response for scheduler request:

... but when I connected the monitor to it, it started working...

So Intel drivers have the same problem as Nvidia a few years ago (drivers at that time did not detect computing capabilities when no monitor is connected. So people invented 'dummy plug')


I installed the Intel application and Boinc is requesting work for it from Seti but haven't received any. Reply is "no tasks available", only for ATI/AMD GPU.

Ask this in "Open beta for OpenCL AstroPulse for Intel GPUs started" so people which use this app can give you advice what to do:
http://setiathome.berkeley.edu/forum_thread.php?id=70717

Astropulse tasks are not always available but since you have no problems to get them for CPU and NVIDIA GPU (and all the tasks are the same):
http://setiathome.berkeley.edu/results.php?hostid=6969332&offset=0&show_names=0&state=0&appid=12

... probably there is something 'special' to do (OpenCL apps for Intel GPUs is 'new uncharted territory' for BOINC)



Will post to the thread, others have had similar problems. Thanks for your advice.

Hi,
I have set up my Intel HDGraphics 4000 for OpenCL and installed Raistmer's application. I noticed that I needed to plug in my monitor to that card to make Boinc or GPU-Z to recognize its OpenCL capability, installing the driver and SDK were not enough. Normally the monitor is hooked to Nvidia GTX 650 Ti.

Now Boinc is requesting work for intel_gpu but hasn't received any, the response is "no work avaliable for Seti Enhanced or AstroPulse 5.05 or v6". For CPU and CUDA I do get AstroPulse WUs and they run OK. This is in Windows 7 64 bit with Boinc 7.0.64.

The 3D Caps Viewer didn't first find the Intel Graphics at all, but when I connected the monitor to it, it started working. Now also GPU-Z and Boinc says Intel has OpenCL. GPU-Z doesn't find Cuda on my Nvidia card anymore but Boinc sees it and crunches away with Nvidia.

I installed the Intel application and Boinc is requesting work for it from Seti but haven't received any. Reply is "no tasks available", only for ATI/AMD GPU.

Thank you for your help.
15) Questions and Answers : GPU applications : OpenCL on Intel HD Graphics 4000 not recognized (Message 1368798)
Posted 17 May 2013 by Harri Liljeroos
Hi,
I am trying to get OpenCL to work on my Intel GPU. The CPU is I7-3770 on a WIn 7 Enterprise 64 bit. So far I have done the following:
- enabled the internal graphics in the BIOS
- allocated to it 512 MB memory in the BIOS
- installed the latest driver for it (9.18.10.3071)
- installed the IntelĀ® SDK for OpenCL* Applications 2013 (64 bit)

The computer also has a Nvidia GTX 650 Ti where the monitor is attached to. It runs the Lunatics CUDA application for MB and the OpenCL application for AP. GPU-Z sees both graphics cards but indicates for the Intel HD Graphics 4000 that no OpenCL is available (shows 0 MB memory for it though). Windows device manager indicates Intel HD Graphics working properly. Boinc is 64 bit version of 7.0.64 and does not find the Intel card.

I have studied the Intel SDK installation notes and checked:
- INTELOCLSDKROOT environment variable points to correct folder
- registry entries mentioned in installation notes are there with correct values

I have Raistmers AP application downloaded but not yet installed. Propably no point while OpenCL support is missing.

Can somebody help, what I am doing wrong or is there still something missing?
16) Message boards : Number crunching : BOINCstats partial graph display (Message 1308043)
Posted 20 Nov 2012 by Harri Liljeroos
I've experienced similar behaviour on my old Compaq/HP 8710w laptop with Win XP. It has a Nvidia Quadro FX 3600M GPU. Some of the graphs on BOINCstats would go black randomly even while scrolling up and down my stats page with FireFox. The symptoms got worse the longer the computer and FireFox were on. Reloading the page with CTRL+F5 might sometimes help or just blacken some other graph on the page. Restarting the computer usually helped for a while but eventually the problem reappeared. Adblock Plus is in use on that machine. IE did not have the that problem and I never used Chrome.

I tried different driver versions but that did not help. I did use that GPU for crunching for a while, but the high temperature did kill the original GPU, so now it crunches only with the CPU. I am currently using the driver version 176.87, which is actually the latest from HP for that machine, but newer drivers directly from Nvidia did not cure the problem.

I just viewed my own stats with that computer using FireFox and the graphs are showing correctly. This might have been the first I've looked at them with this computer since the layout was changed at BOINCstats. The computer has been on for about a week but it hasn't been used for anything else than crunching and I could not reproduce the problem. I'll leave the FireFox on and try again later to see if the problem still persists.

Posted 1 Oct 2012 by Harri Liljeroos
Something certainly "wasn't right" this time round. despite everyone trying to get uploads (and for that matter downloads) the thin blue line fell to the bottom and stuck there for most of Saturday and Sunday (UK times). When it picked up there was quite a surge in it, now settling down to its usual level - I reckon there was a visit from a tyre kicker sometime Sunday evening (UK time) along with the end of the Astropulse production.


If you look closely to the graph, you'll see that it has automatic scaling and the bottom is now 10 Mbit/s. So it was still receiving quite a lot of data even in worst situation.
