Problem in building CUDA-GPU port with experimental MAGMA support

Hi,

First, let me give my system specifications:

CPUS: 2 x Intel(R) Xeon(R) Platinum 8160 CPU @ 2.10GHz
GPUs: 1 x NVIDIA Corporation GP100GL [Quadro GP100]
OS: Red Hat Enterprise Linux Workstation release 7.7 (Maipo)
Compiler: Intel Parallel Studio 2019 update 4 cluster edition
CUDA: cuda 10.2.89_440.33.01
VASP: 6.1.0

I face some problems in building the VASP CPU and GPU versions before trying to add MAGMA support, but I could eventually figure them out and install all executables (vasp_gam, vasp_std, vasp_ncl, vasp_gpu, vasp_gpu_ncl) without an error. I documented issues I faced during building these versions of VASP here in case you are interested. Then, I tried to build the GPU port with the MAGMA support as I read somewhere that it can have a significant effect on the performance. To build the MAGMA support, I made following changes in the make.include file:
  1. I added -DUSE_MAGMA to CPP_GPU
  2. I added path to MAGMA to the end of the file: MAGMA_ROOT := /usr/local/magma/lib
The installation went on for a while but stopped with following errors:

subrot_gpu.F(999): error #6633: The type of the actual argument differs from the type of the dummy argument. [COVL]
CALL cublas_Set_Matrix(NB_TOT,NB_TOT,int(c_sizeof(COVL(1,1)),c_size_t),COVL,NB_TOT,GPU%COVL,NB_TOT)

make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/khalkhal/Downloads/vasp.6.1.0/build/gpu'

I am not an expert in programming but I can tell this is a FORTRAN compiler issue. Does anyone know how to solve this? I highly doubt that the solution is modifying the source code! I couldn't fine any guideline for building the MAGMA support so any help would be appreciated.

Thanks
