	Hi there, at the moment, one of my machines has some problems with NATHAN WUs. They are running for days without end and I have to abort them manually. The stderr file shows "Out of GPU memory". That's interesting, since the card is a GTX480 with 1.5GB RAM. In the past there was no such problem with the NATHAN WUs. My other GPUGrid machine, equipped with two GTX560Ti, seems not to receive any NATHAN WUs. How can I suppress those WU type ? best regards, Rene

That's interesting, since the card is a GTX480 with 1.5GB RAM. It's interesting because these workunits consume only 670MB (GPU) RAM. Is there any other GPU application running on this host? In the past there was no such problem with the NATHAN WUs. I don't have such problems with these workunits now, however I don't have any GTX 480s in my machines at the moment. Maybe you should try to uninstall your old GPU driver, and install the latest one. My other GPUGrid machine, equipped with two GTX560Ti, seems not to receive any NATHAN WUs. That is only a matter of chance. How can I suppress those WU type ? You can't. You can only choose between the long and the short queue.

	Did you try rebooting the computer to free any 'stuck' memory?

Do you think this might cause these problems ? It's worth a try to stop it, and simplify your BOINC configuration.

	Hmmm...at the moment a NOELIA WU is running fine and this morning a SANTI was completed without error. Lets see what happens next... ;)
