All,
I’m using an Nvidia 8800 GTS 640Mb card and all the Cuda Sample Programs work except the Eigenvalues. I’m using NVIDIA Driver Version: 173.08.
My real simple Cuda programs work ok as well. Device values are:
[font=“Courier”][root@zoozesrv release]# ./deviceQuery
There is 1 device supporting CUDA
Device 0: “GeForce 8800 GTS”

I’m not 100% cure why but this is the output I’m getting:
[font=“Courier”][root@zoozesrv eigenvalues]# ./eigenvalues

Although this doesn’t really bother me as its doing what I want it to do, I’m not 100% sure why this sample program fails (I’m afraid some of the maths is beyond my aging brain).
Any help would be most appreciated, kindest regards
