Hi,
Is this possible or all cusparse\cublas function can be called just from host?
I have an algorithm that includes tridiagonal solver and i want to use cusparse instead without the overhead of going back to the host can i do that?
cublas functions can be called from the device. There is cublas documentation and there is a sample code that demonstrate how:

As far as I know, cusparse functions cannot be called from device code.
