Occasionally I also encounter this problem: there is some mismatch 
between the MPI libraries linked by the compiler and those loaded at 
run-time. Ensure that your NVidia HPC SDK is properly set up, that 
environment variables have the correct value, that the mpif90 you are 
using is the one in the NVidia HPC SDK and not something else, same for 
MPI libraries, ...
