Post:
I have recently installed 7.6.33 on a Win10 Pro machine and after running for a while get a message that my password is invalid. BOINC then shuts down the work units from the projects that I am running and deletes the data from the tasks page (doesn't delete the projects or any work done). Shutting down and restarting brings the tasks back. Have re-installed 7.6.22.
Similar problem here. Getting password is invalid pop-up error messages several times a day. BM 7.6.33x64 with V-Box. W10ProX64.
Temporary fix from Boinc Manager (advanced view), File Tab, Select Computer, & click on local host (or the name of your computer).
Noticed a couple of headless VM beta tasks (ALICE) had failed after the last blank-out. Nothing in the Windows log files.

It appears that FiND staff (Dublin, Ireland) gave GridRepublic (Boston, USA) the FiND project, Boinc user accounts and all.
GridRepublic seem to be (and correct me if I'm wrong) sending Charity Engine tasks to FiND account users.
Charity Engine seems to be a trade name for the Limited (for profit) company (registered in the UK) The Worldwide Computer Company Limited whose share holders include David Anderson.
This company appears to sell our computing resources.

So, Dave, perhaps you would be so kind as to let us know what's going on?

Post:
Most Boinc projects use 1 logical thread to process 1 WU.
When Boinc is configured to use 100% of the CPU, it would in your case process 8 different tasks, each on a different thread. You can set Boinc to use less if you wish.
The exception to this is MultiThreaded applications, which can use many threads simultaneously. Not many projects have MT apps.

GPU tasks tend to use a full GPU + part of a CPU thread (up to 100%).

This is not a new problem, but finally I decided to report it as I couldn't find a solution. I have AMD Radeon HD5850, which I believe is supported, but my GPU is not used. The message in the log is "No usable GPUs found".

Below are a little edited messages from the log file.

I used to run the client as a service, but reinstalled to be run under regular user account a long time ago, but that did not solve the problem. It is not run in a virtual client, even though VirtualBox is installed on my machine.

My video driver is 13.9 (well, not exactly the driver version, but package version) so it's quite recent.

Is this a bug in the detection process, or something wrong with my system?


While this may stem from using different user accounts and security, my guess is that your problem is related to the fact that you use to have Boinc installed as a service - which can prevent GPU's from working. I expect something of this old installation remains and was not properly replaced when you reinstalled Boinc to run as a non-service (now the default with the latest release).
I suggest totally uninstalling Boinc; delete the folders (x86 and x64), any Boinc 'user' accounts, clear any registry entries and after a reboot, reinstall Boinc (by right clicking and running as an administrator, then selecting advanced and making sure all users are selected. Probably best to close your anti-everything when installing). Would also recommend using the latest version of Boinc (7.2.28 x64).

BTW, (and unrelated to your problem) 4.2.18 is bad for some Boinc projects. 4.2.16 is the last good one.

6) Message boards : GPUs : multi GPU's may cause CPU cores to not be "fully" utilized (Message 49305)
Posted 25 May 2013 by skgiven
Post:
In this situation CPU utilization depends on three things:
The amount you tell Boinc to use (99%)
On what the scheduler reads as being required for the GPU apps
On what the apps actually uses

If an app says it needs 50% of a logical CPU, then task scheduling will go by that. If it says 10% or 90% then the scheduler will start up work going by that.

However, what the app actually uses is another matter, and the estimated CPU requirement is often inaccurate.

So with 2 GPU's and a 100% CPU usage setting, you could be using just over 10 of 12 threads (app says it needs a full CPU but uses next to nothing) or trying to use closer to 14 (app says/is told it needs 0.001 CPU's but uses a full CPU thread).

The CPU resource requirement read by the scheduler is based on average CPU requirements of the app. However, for some projects, some GPU WU's use more of the CPU than others, so the specified CPU resource requirement is inaccurate.

You could use app_config.xml files to specify the amount of CPU each GPU app uses and be closer to the mark, if you keep it in line with actual observed usage, say going by Task Manager. This would make the scheduler more accurate, and resource utilization potentially better, but as soon as a different WU turned up the accuracy would fall.

FIX #2: Modify the start-up sequence of the /etc/init.d/boinc-client script.
(a)I got this from gfarmerfr an ATI/Ubuntu user on the DNETC forums after telling him how I was putting the delay in. I haven't actually tried it. It worked for gfarmerfr and he knows what he's doing. I believe this was tested on v9.10. In many ways this is a better fix but I was already into the script for other reasons (adding fan speed control) so I stuck with my sleep 6 version.
(b)Execute the following two commands to move BOINC start-up to the end of start-up processing:
sudo update-rc.d -f boinc-client remove
sudo update-rc.d boinc-client defaults 99

This fix worked for me with Ubuntu 13.04, Boinc 7.0.27 (x64) - Used as root wasn't owner in fix1.

I'm also using an NVidia GTX650TiBoost with 304.88 drivers (released 3weeks before the GPU).
8) Message boards : Questions and problems : Project hogs do not seem to obey BOINC computing limits (Message 48906)
Posted 1 May 2013 by skgiven
Post:
You might want to indicate the projects you are actually running, especially any GPU projects.

If you have 4 cores and you tell Boinc to only use 75% of them, it will use 3 cores. If you say 90% or even 99% it still means use 3 cores. The GPU usage tends to be an estimate, and not always accurate. Some GPU WU's use high amounts of the CPU during some stages of the run, especially at the start, and lower amounts at other times. Overall it might be fairly low, but at some stages it will be a full core. Do you observe this behavior when a GPU task starts?

Hi Richard,

Yes, for Sim1 the mt problem(s) existed with 7.0.28, 7.0.42 and still exist with 7.0.44

W7x64, i7-3770K (8threads), 8GB DDR3, SSD, GTX660Ti + GTX470 (and same issue on a different rig).
When CPU usage was limited to 75% (Boinc Manager) Sim1 grabbed all 6 'available' CPU threads, and thus interfered with GPU crunching:
I was running POEM on the GTX660Ti, with the GTX470 excluded as that fails - a project-specific multiple GPU issue. So app_info used to run two or more tasks at a time for POEM (1 CPU each), and cc_config preventing GPU in slot 1 (GTX470) from being used for POEM. The GTX470 was running Albert work (just one task at a time and 0.23CPUs).
When Sim1 started the GTX470 stopped running tasks (being in slot 1 and Slot 0 rightly getting preferential treatment) but the GTX660Ti only ran one task.
Before running Sim1 the CPU usage was just over 75% so Boinc was reserving cores for the GPU's according to the app_info.
When Sim1 started the CPU usage rose to 88 or 89% (so 7 CPU cores were being used)
When I reduced the number of CPUs to use (74%) Sim1 stopped, waiting for 6CPU threads to run on. If I then exited and started Boinc it still waited for 6CPU cores - so it would never finish!
When I increased the CPU back to 75% Sim1 started again. CPU usage rose to 88% and one PEOM task ran. I suspect the manager or Sim1 is not fully aware of the app_info settings.
When I increased the CPU to 99% a second POEM task started on the same GPU (as it should be). Actual CPU usage was now at 100%.
When I increased the CPU from 99% to 100% (all 8threads), device 1 started to be used (GTX470 running an Albert task).

You can't keep the CPU count at 100% or Sim1 will want to run the next task on all 8threads.

What we need is Sim1 (or any mt app) to count the number of available CPU's and subtract the number used by GPU's. I'm not sure where the mt app gets its available CPU count from, but it seems to be a different place than the non mt apps, as only 4 CPU tasks normally run on that system when I'm running two POEM tasks and have the CPU set to 75%.

If you want any further testing, let me know what flags to set, in addition to cpu_sched_debug.
12) Message boards : Questions and problems : Multi-core Computing (Message 47351)
Posted 17 Jan 2013 by skgiven
Post:
If an mt-app, such as Sim1, runs using all the CPU cores/threads, and there is a GPU in the system, no work will be done on the GPU while the mt-app is running. Hardly a desirable situation! While Virtualization can be used to better allocate CPU and GPU resources, setting up and maintaining VM's is hardly something for the average cruncher and performance tends to fall.

Normally it's more productive to run 'single-threaded' tasks, and the best way for task sizes to be controlled is at the project level. Climateprediction have already created smaller models to accommodate lesser systems and infrequent users.
Years ago I was told that it wasn't possible to run one climate model on multiple processor cores. I expect that hasn't changed.
13) Message boards : Questions and problems : Bug in newer server code for computer preferences ????? (Message 47350)
Posted 17 Jan 2013 by skgiven
Post:
I think there are some differences between server versions, and IIRC some projects allow you to set one of the non-default/primary Preferences as the Default Preferences. So, for example on one project Work could be the Default project.
14) Message boards : Questions and problems : Project status = Suspended - Computer is not in use (Message 45013)
Posted 21 Jul 2012 by skgiven
Post:
Most projects allow you to configure this online, in Computing Preferences:

Suspend work if no mouse/keyboard activity in last
(Needed to enter low-power mode on some computers)
Enforced by version 5.10.14+ 0.0 minutes

If it's set to "0.0" or "---" minutes it should prevent this.

If you chose Run Always from Boinc Manager this should also force the system to always run.

The message in Boinc Manager's even log is "Suspending computation - no recent user activity", however it's easier to see by looking at the Tasks; these will show "Boinc suspended computer not in use".

While there is a W8 Pro version, by 'Pro' I just meant a professional version, as opposed to a home edition version that can't be added to a domain, and is likely to be missing things.
The actual name is 'Windows developer preview' (WindowsDeveloperPreview-64bit-English.iso), apparently not on your list either.

Anyway, with installer problems and 6.12.38 disabling the GPU/preventing recognition, I am a long way from being able to test any GPU project.

Some CPU projects might still be interested in testing W8. So far as I can see, it works reasonably well; for a pre-beta using a Boinc-beta. Did notice a few tasks fail after forcing a reboot once, they did not recover from their last checkpoint, but that's about it so far. Lots of other programs don't work too well (including CPUZ) but Boinc is surprisingly stable.

Tried that from the command prompt, but it said I already was a member of the boinc_admins group. Also, added my account to the boinc_users group, but made no difference:

Logged on as an administrator, ran the Boinc Install as an administrator, but got the same message,
    Failed to add user to the 'boinc_admins' group (BOINC Master).

Not really sure any of that was applicable; I expect W8 Preview is a Pro version.
So could this just be an issue with the Boinc installation software?
Perhaps not getting a recognized response from the system when attempting to add to the boinc_admins group? I mean it's not written for W8 and the wizard reports that it was interrupted following the above error message.

PS. An alternative to trying this from the command prompt for W8, would be:
Start+R, MMC, add local users and groups snapin, save to desktop, close, right click and run as administrator, change user memberships.

Installed W8x64 and Boinc 6.10.45 (as no other Boinc version would install) - so trying to test the only version of Boinc that works on Win8 (and DC's) :(

280.26 NVidia driver installed without a hitch, no probs during install and looks good in Device Manager, but not getting tasks from Einstein, which says I don't have an NVidia GPU (obviously restarted a couple of times).

1 x Nvidia Tesla C2070 (cost roughly $4000)
No, No, No


4 x Nvidia GTX 580 Liquid Cooled (cost roughly $700/ea)

yes... or 3 x Nvidia GTX 590...

Liquid Cooled - Not needed; get good cards and use MSI Afterburner to control fan speed and thus temps.

ONE GTX580 would do more work than a C2070!

Three GTX590's should do slightly more than 4 GTX 580's.

You would need a very good PSU.
Better with 2 i7-2600 based systems, each with 2 GTX580's or GTX590's, than one system.

Credit depends on what project you want to crunch for.

GPUGrid does HIV, Cancer and Amyloid Docking work amongst other Bio-Scientific research. A Worth While project IMO, whatever the credits.

There you could get over 500,000 credits per day with 4 GTX580's, but exactly what would depend on configurations, apps, operating system and task type.

Ask there for advice if you are interested.
