culaInitialize now fails

[jmorgie]

This app used to work.

Now:

s=culaInitialize ();
give s=10.
culaGetError gives "49"

what is happening? this used to work. Now i am revisiting a simple app to debug some new stuff but cula wont initialize.

thanks

I believe i do have all the correct components: cuda 3.2, cula r10 and latest nvidia driver. this is all code that worked last monday and nothing changed in the interim. i will look again; any other thoughts about what could be an incompatible context?

thanks

I am thinking that my gpu board did not survive the trip home from hawaii last week.

on the plus side, I use it as the display driver and my display is fine. but otherwise i cannot explain the bad context errors.

do you have / know of / a gpu diagnostic?

I use the NVIDIA GPU SDK to diagnose errors. First, run deviceQuery, then try out the bandwidth tests. They are enough to show base functionality.

There's a half chance that Windows got sneaky and did a Windows Update to an older WHQL driver when you weren't looking.
