Hello:

following the instructions under wiki/index.php/OpenACC_GPU_port_of_VASP#Building I used the file arch/makefile.include.linux_nv_acc that is identical with this wiki/index.php/Makefile.include.linux_nv_acc.

After running "make gpu" I get this error:

Code: Select all

nvc-Error-Switch -I expects an argument
-I<incdir>          Add directory to include file search path

I could fix this by adding

Code: Select all

MPI_INC = $(NVROOT)/comm_libs/mpi/include

to makefile.include. After "make veryclean; make gpu" I get a bit further another error:

Code: Select all

/software/all/devel/nvidia_hpc_sdk/21.2/Linux_x86_64/21.2/compilers/bin/nvc   -m64 -DKERNEL_DP -DKERNEL_ZP -DDEBUG -DUSE_STREAM -DMPICH_IGNORE_CXX_SEEK -D__PARA  -I/include
 -I/include -I/software/all/devel/nvidia_hpc_sdk/21.2/Linux_x86_64/21.2/comm_libs/mpi/include -I. -I/include -I/samples/common/inc  -DUNIX -O3 -g  -o obj/x86_64/release/fortran.c.o -c fortran.c
"fortran.c", line 68: catastrophic error: cannot open source file "cuda_runtime.h"
  #include <cuda_runtime.h>

I fixed this with adding this line to makefile.include:

Code: Select all

CUDA_ROOT = $(NVROOT)/cuda
[\code]

but now after long compiling I get this error:

Would you please tell me what I am doing wrong? Please find attached full make logs. Thanks in advance!

Best regards,

Hello everybody,

I would only add that the depricated CUDA-C build worked in the identical settings. I would appreciate very much if someone can give me a hint how to solve the issue with the OpenACC build. Thanks!

Best regards,
Ivan

Please try using make std, gam and ncl, since the open ACC code uses precompiler flags to distinguish it from the normal code.
