Release 4.0.17 not working for Windows Server 2008 R2


On our Windows Server 2008 R2 I tried updating the CUDA toolkit to the current release 4.0.17.

After doing so, I get an “Initialization Error” in all CUDA programs including those from the SDK.
After reverting to the release candidate 2 (4.0.13) the problem was gone.

I am using the Tesla TCC driver for Windows Server 2008 R2 (270.61) which seems to be the latest one available !?

best regards Rolf

270.61 doesn’t support 4.0 final, and is running behind the time being, run 270.81 from the CUDA 4.0 download page, or wait for 275.xx drivers to be posted on the site (I’m told it should happen today)

Just for clarification because this is not stated clearly on the CUDA 4.0 website:

Does the “development driver” for Windows 7, 64 bit support

a) Windows Server 2008 R2

b) TCC mode for using CUDA via remote desktop

Is the TCC mode a general option included in the latest driver versions by default?

Are the Windows Server 2008 R2 drivers identical to the Windows 7 drivers?

So far I stayed away from the regular development driver since I was told they do not support TCC mode which is mandatory in our case.

In any case, it would be great to state that explicitely on the download page to avoid confusion!
