Put this host on AP27 and got errors -- tasks immediately errored out.

Configuration is quite similar to this host which runs AP27 successfully. The only obvious difference is that the host with errors has 2 GTX1080s instead of one.

Is anybody running AP27 successfully on a system with 2 GPUs?

Any other ideas what the problem might be?

The obvious first thing to try would be to remove one of the GPUs and see if the problem goes away.

Yes, see this machine.

Can you verify that it is running on each GPU and not trying to load both AP27 runs on one card (there were some issues with this in earlier beta versions of the app)? Maybe run GPU-Z to verify each card is under load?

You might also try to update to the latest driver (a newer one came out on 8/15).

I don't think GPU-Z would help in telling whether it's trying to run them on the same card. The tasks error out immediately upon starting to execute.

Is there a log that might allow me to tell whether they tried to run on the same card?

BOINC event log only gives me this:

gpuz can tell you if the driver installed properly and the opencl library is usable

check to see that OpenCL has a checkmark for each gpu down at the bottom of the GPUZ screen

It's possible that the ocl library cannot be loaded resulting in the app not being able to start, which would lead to a stderr.txt similar to yours

By the way i'm running a 2x nvidia host and a 3x amd host

Although the tasks haven't validated yet, this system is not erroring out immediately, so it doesn't seem t a be a probelm with dual GPUs. Will troubleshoot the problem system when I have time.

By the way i'm running a 2x nvidia host and a 3x amd host


That was the problem -- driver update fixed it (although the update behaved oddly).

I had other systems that were broken by driver updates for Windows 10. This system might well have been running manual sieving and received the update without my noticing the problem.
