Cublas saxpy error

Thanks Mat,

now it works well, also if performance are more or less the same (the code is memory bound). What I don’t understand instead, when I use cublasSaxpy in a real big code, I get:

NVFORTRAN-S-0155-Could not resolve generic procedure cublassaxpy

From here:

I read could be a parameter mismatch, but parameters are right in my code. Any other possible causes of such error? Thanks:

  subroutine project1_a_omp(xbar,bbar,b,xx,bb,n,m,w,ifwt,ifvec)

  use cublas
....

!$OMP TARGET DATA MAP(TOFROM:alpha)
      do k = 2,m
        alpha_d = alpha(k)
        call cublasSaxpy(n, alpha_d, xx(:,k), 1, xbar, 1)
        call cublasSaxpy(n, alpha_d, bb(:,k), 1, bbar, 1)
        call cublasSaxpy(n, -alpha_d, bb(:,k), 1, b, 1)
  enddo
....

!$omp end target data
