I think it is big bug with the function getrf and gesv! When I use geqrf, it goes well.

Re: Runtime error (4)!!
I noticed in another thread you were talking about using zero-copy memory, which is unsupported in CULA. If you're trying to do that here it could explain your error.
I'd recommend that you explore using the host memory interface because it is the easiest to use and in mosts cases it actually provides the best performance.
