This may add even more

This may add even more confusion, but anyway: Apparently something went wrong with the optimization during compilation of the 1.07 Linux CUDA App, i.e. the CPU-Part is probably slower than it could be.

We already have a set of new Linux CUDA Apps built, I intend to publish these tomorrow as version 1.08.

Sorry for the confusion. Oliver is on his well-deserved vacation now, and we wanted to fix the existing problems before he left, but that went a bit hastily.

do you mean fullCPU app or 270 app?

Now I'm really confused and I do not understand, what to do.

I'm running with win7-x64 and the 260 NVIDIA driver. I'm not using any Linux. What do I have to do, to fix the cross validation problem? I should mention, that I'm using an app_info file on some of my computers.

Regards

Bernhard

Hi,

AFAIK, the newest Windows-driver (266.58 as of now) does not have the problems the Linux-driver has (but this is related to CPU load only?).

So removing app_info or updating app_info, so you use the latest E@H binaries should be enough.

Thanks Michael I've

Thanks Michael

I've updated the app_info file with the newest app version and it works.

The scheduler has been

The scheduler has been modified and the Linux 1.08 Apps published.

If running Windows, you should automatically receive the new 1.07 App (plan class "BRP3cuda32").

If running Linux and you have the beta driver 270 installed, you should get an App version 1.08 plan class "BRP3cuda32nv270".

If running Linux and not have installed the 270 driver, you should get an App version 1.08 plan class "BRP3cuda32fullCPU". This App includes a workaround for a problem that is present in NVidia drivers prior to 270 and requires a full CPU core to run.

In case you're using an app_info.xml, you're on your own anyway. You should probably download the new App that fits your system and update your app_info.xml.

Note that all of these new apps fix known validation problems.
