Using nvhpc intrinsic mpicxx compiler error

Hi,

I am using GTX960M, toolkit version is 11.0.
I am trying to compile a MPI included code with nvhpc compiler. According to some online search, I am using mpicxx to compile the code. the compilation goes well. However, when I try to execute the executable, it shows:

[wending-Inspiron-7559:60852] [[INVALID],INVALID] ORTE_ERROR_LOG: A system-required executable either could not be found or was not executable by this user in file …/…/…/…/…/orte/mca/ess/singleton/ess_singleton_module.c at line 388

Sorry! You were supposed to get help about:
orte_init:startup:internal-failure
But I couldn’t open the help file:
/proj/nv/libraries/Linux_x86_64/openmpi/2020/192603-rel/share/openmpi/help-orte-runtime: No such file or directory. Sorry!

*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[wending-Inspiron-7559:60852] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!

I am pretty sure these error message does not come from my code. Would you please suggest about these strange error messages?

Thanks

Besides, I also tried the sample code in https://docs.nvidia.com/hpc-sdk/compilers/hpc-compilers-user-guide/index.html#mpi-use

Same error message comes out.
