Pinned memory for diagonalization dsygvd (Divide and conquer)

For solving a problem of the form: AX=B There are two options: magma_int_t magma_dgesv (magma_int_t n, magma_int_t nrhs, double *A, magma_int_t lda, magma_int_t *ipiv, double *B, magma_int_t ldb, magma_int_t *info) magma_int_t magma_dgesv_gpu (magma_int_t n, magma_int_t nrhs, magmaDouble_ptr dA, mag...

vl and vu DSYGVDX_2STAGE

I'm using Fortran as the programming language of a software which requires to diagonalize a matrix. I've already implemented a function which makes use of magma_dsygvd_m . However, it is not as fast as I would have expected and I would like a speedup. When trying to implement magma_dsygvdx_2stage , ...

I put the flag you suggested everywhere, but still fortran.o does not appear.
I'm using CUDA 10.0, gfortran-7 and magma-2.5
