Re: [petsc-dev] invocation of nvcc

4 Nov 2021


      Correction it is nvc:

nvc-Warning-The -gpu option has no effect unless a language-specific option
to enable GPU code generation is used (e.g.: -acc, -mp=gpu, -stdpar, -cuda)

And I add  -mp=gpu to CUDAFLAGS

Does anyone know if PETSc calls nvcc and hence can add flags to the
invocation? nvcc wants a flag like -mp=gpu but I don't know if we do that
or a compiler wrapper in the environment.
