At present, we do not have a well-documented C++ interface for writing simulation scripts.
But we have the SLI interpreter, which allows you to control NEST without the Python
intepreter. The SLI language is based on PostScript, i.e., is a stack-based language with
reverse Polish notation, see
We have had success using Intel VTune to profile NEST, even with Python "on

Recently, I've been trying to test NEST's performance(with and without MPI).
But with PyNEST, it's hard to do more detailed testing with tools like Gprof.
Only some print-time and memory methods can be inserted into the C++ source code for
Is there a C++ front-end interface that can call NEST C++ source code for testing?
Of course, I used some of Python's performance testing tools, but only to the
interface, not C++ in action.
I'd appreciate any tips on how to test NEST's performance!
