Topic 197459

Hi, I just installed a Nvidia Quadro 2000 card in my computer and it started crunching but after about 1,5% it went missing. I tried rebooting both BOINC and Windows but nothing helps. In the event log there is an entry 'No usable GPUs found'. This is on Windows 7 x64.

GPU missing waiting to run

Well your pc says it has a task running but at the same time your GPU is not recognized http://einsteinathome.org/account/130742/computers

Are the drivers up to date??

I installed the card

I installed the card yesterday. Then I installed the latest drivers. It was detected right way and started crunching. But just after 1,5% another task was started and since then I can't get it running. After the first run it was detected by BOINC as I checked the event log. No the event log says no suitable GPUs found. Really strange.

I uninstalled, rebooted Windows and installed again. This is the event log:

Are you sure that Windows, in

Are you sure that Windows, in its infinite wisdom, didn't treat your drivers as old and inadequate, and that it installed 'the latest, best, and WHQL' all by itself? As these drivers that come from Microsoft themselves, don't contain things like OpenCL and CUDA.

Double check that you use these drivers?

BOINC only checks for capable GPUs at BOINC startup, and can only do so when a driver is installed that contains OpenCL or CUDA support. Any driver that doesn't have these components included will give "No usable GPUs found".

Apropos, other cases in which BOINC stops running GPU work are:
1. When BOINC is installed as a service. As then the drivers run in a different session than the Windows user account does, and therefore the correct drivers cannot be found any longer.
2. When you use Fast-User Switching. For then the drivers may be loaded for the first user, who also installed BOINC. But they're not loaded for the second user.
3. When using remote desktop. When using the remote desktop, Windows uses a driver that contains nothing, but for basic 2D and 3D components. This driver cannot be updated. It's to make sure that any system out there can show the Windows desktop of the remote computer.

All of those cases are Windows things. Not much BOINC can do about to change that.

"Remote desktop in use;

"Remote desktop in use; disabling GPU tasks"

I learned the hard way you can't connect to a box running GPU tasks using remote desktop. It replaces the real drivers with fake ones. If you need to remote to the box you have to use a VNC solution.

Not fake ones, just drivers that don't contain many special hardware requiring things. This to make it compatible with any system out there. Even a computer with a 1 megabyte videocard can be used to RD into a Windows 7 computer.

Starting BOINC from a

Starting BOINC from a physical screen solves the problem. If I then disconnect the screen or switch to another source is it going to continue to use the GPU?

Do you mean just unplugging

Do you mean just unplugging the monitor from your GPU card?

If so then that is no problem since I do it several times a day since I use just 2 monitors on 5 of my desktops since GPU's here is their only job (pretty much anyway)

Yes those drivers get updated quite often and that is not even including the "beta" drivers.

In fact I just updated the driver on my NVIDIA GeForce GTX 650 Ti (2047MB) to driver: 33528 tonight.

I don't have a Quadro 2000 but you can run the Auto-Detect @ the GeForce site.

If you just turn it off, unplug it, switch a KVM to a different box, or anything like that, yes, it will continue to run.

Logging in from another computer using Windows Remote Desktop Connection stops GPU crunching. I use teamviewer.com to remote in. Install the app on every computer you want to remote into, plus the one(s) you will be remoting in from. If everything is set right, you won't even need to enter passwords (unless the remote box has restarted and you haven't logged into it in person). There's also a web login that I use at work where I can't install software.

Does this include boxes that auto start into a user account? I have some Boinc only machines and have set all of them to auto logon to an account that then crunches, would Team Viewer work in those cases? Would each pc have to use the same account name? I use UltraVNC now but have to use a password for each pc when I log in from another pc. It isn't hard or anything like that, in fact it's pretty easy, but I cannot log in from outside my home network. That is probably a user setting that I haven't found yet though.
