I 've just instaled CUDA 3.1 and run the example simplecublas.exe and it does nothing because sais “CUBALS inicialization error”.
I 'm using NVIDIA GEFORCE 8400 MGS with capability 1.1. I dont understand because I didn’t compile the example before executing, I 'm runnig the example of the SDK. And I tried to execute an example only with the minimun code to run a cublas example, and I have the same problem, without compilance or linker errors.
Maybe its a problem of the last version? Has anybody the same problem??
Can you give some more information about your computer? Operating system? GPU RAM? Wikipedia lists 128MB and 256MB as possible configurations for GPU RAM. If you’ve only got 128MB then your card isn’t CUDA compatible. If you’re using Vista or Windows 7 with Aero enabled then you may need to switch off Aero to free up some GPU memory.
I’m using Windows Vista Home Premium. This is the information which appeared when I exected deviceQuery.exe from de SDK code.

SKDs samples from version 3.0 run without problems, but all the samples from the SDK 3.1 dont’t run. Oly runs deviceQueryDrv.exe, maybe the new CUDA version doesn’t run over my GPU, I like new version because they improve CUBLAS and you can do printf in device code. I think I have to use 3.0 version.
Finally, I found the problem. With previous version, I don’t have to change my graphics configuration because my GPU have 256MB and it was enough, but the new version maybe needs more memory to execute the app and I chaged it as you tell me and it works!!
Thank you very much.
