Strange results from Nvidia compiler: vasp 6.4.2

Posted: Fri Sep 22, 2023 1:19 pm

Hello all,

We have 2 suits of compilers on our IBM Power 9 machine: gnu (11.2.1) and Nvidia HPC SDK (23.7 and earlier versions). I found out that vasp executable made from Nvidia compilers crashes on the first ionic step for many well known structures, while GNU compiled executable works fine. It is a CPU version.

nvhpc executable:

I tried everything with Nvidia compilers - no optimization, different libraries. Nothing helps. What can be an issue?

Thanks,

Dear Sergey,

please provide us some input and output files (preferably for a small system).
We would like to reproduce your problem.
Also, please let us know which libraries (and versions) you use to compile and link vasp to.
If possible, please upload also the makefile.include used.

Good evening,

I apologize for the late reply.

Please find attached the set of input files and makefile.include I used. The test file is not small, but it really takes 5 minutes to get this error.
I used lapack/blas/scalapack as shipped with Nvidia SDK set, and FFTW-3.3.10.

Dear Sergey,

Please upload the input files including OUTCAR of the successful run as well.

Dear Sergey,

inspecting your makefile.include I found a few points that might be responsible for the issue.
You set a global -O2 optimization flag with following

Code: Select all

OFLAG       = -O2 -fast -Mcache_align
The recommended makefile.include for nvhpc typically have only a

Code: Select all

OFLAG = -fast
If possible, please use the latter.

Furthermore, it seems you have compiled your own scalapack with

Code: Select all

# BLAS (mandatory)
BLAS        = -lblas

# LAPACK (mandatory)
LAPACK      = -llapack

# scaLAPACK (mandatory)
SCALAPACK   =  -L$(HOME)/arch/nvhpc/scalapack-2.2.0-spectrum_mpi/lib/ -lscalapack -llapack  -lblas
We usually recommend to use the scalapack shipped with the hpc_sdk suite.

Last but not least and maybe most important.
It seems you compiled fftw with hpc_sdk and link your vasp executable to this library with

Code: Select all

# FFTW (mandatory)
FFTW_ROOT  ?= $(HOME)/arch/nvhpc/fftw-3.3.10-nv23.7/
If this is correct, then please try compiling fftw with gcc and link vasp to it.

Here is a good output: vasp compiled with GNU-11.2.1 and OpenMPI, OpenBLAS and FFTW compiled with gnu.

I think you are correct in your suggestion: it was caused by nvidia compiled FFTW. If I use GNU compiled FFTW, this error disappeared.

Thanks for your help!
