Everything that compiles for Linux can also be compiled for the Vector Engine. The compilers support Fortran 2003, with extensions from Fortran 2008, as well as C++14. The compilers are able to vectorize and auto-parallelize loops. For general parallelization OpenMP and MPI will be supported.

So I guess you can give it a try [using MPI provided by NEC] and see how it goes..

[assuming they also provide blas/lapack]

./configure --with-cc=mpicc --with-fc=mpif90 --with-cxx=mpicxx --with-blaslapack-lib="-lneclapack -lnecblas"

And if needed - the additional option --with-batch=1

Once this works - you can try additional build options.
