Hi - I am facing issues installing VASP.6.4.2 in GPU. Following are my loaded modules -
/usr/local/apps/cuda/hpc_sdk-12.2/modulefiles/nvhpc/23.9
gcc/10.2.0
PrgEnv-intel/2022.1.0

I am using makefile.include.nvhpc_acc and changed the mpif90 to mpiifort

FC = mpiifort -gpu=cc60,cc70,cc80,cuda12.0
FCL = mpiifort -gpu=cc60,cc70,cc80,cuda12.0 -c++libs

BUT seeing following error :

ifort: command line warning #10006: ignoring unknown option '-gpu=cc60,cc70,cc80,cuda12.0'

Warning: the -fast option forces static linkage method for the Intel(R) MPI Library.
ifort: command line warning #10006: ignoring unknown option '-gpu=cc60,cc70,cc80,cuda12.0'

How to resolve that issue?

I am seeing following error now - my nvfortran and mpifort is working

But the compilation exit out after 25-30 minutes with this line
NVFORTRAN-S-0926-Syntax error in #if (main.F: 969)
NVFORTRAN-S-0918-Missing #endif (main.F: 6151)

Dear subrate_kundu,

For compilation with openACC support for NVIDIA GPUs, you need to use the NVIDIA Fortran compiler (nvfortran), not Intel's Fortran compiler (ifort or ifx)

Can you change back to "mpif90" in your makefile.include, and make sure that the right compiler is used when calling mpif90? Do this by executing:

Code: Select all

mpif90 --version

You should see something like:

Code: Select all

bash-4.4$ mpif90 --version

nvfortran 22.9-0 64-bit target on x86-64 Linux -tp skylake-avx512

Please consult our wiki article on the openACC port and the links therein for more information.

If you already changed your compiler back to mpif90 (I am not quite sure after your second post), please post your toolchain and makefile.include so I can help you further.

All the best, Michael
