* cuBLAS interface (optional)
We propose a cuBLAS version of some QMCkl kernels. However, because cuBLAS is written in C, we need to define a Fortran interface for it. We start by defining functions to manage the cuBLAS handle structure from Fortran, before writing interfaces for the specific cuBLAS functions we are interested in.
TODO These are the C functions that are supposed to be called from Fortran. We still need to write the interfaces themselves.
