     As a commenter said, your example is more functional programming than declarative programming, although the two are similar in some respects. In real declarative programming, you'd be more results oriented -- you'd be specifying what to do with the interesting elements in the list, rather than transforming the list for its own sake. A rule engine like Jess is an example of a declarative programming system (disclaimer, I'm the author of Jess.)

     To answer your one simple question: yes. All functional or declarative programming systems involve a runtime system that has to be implemented on the real computer the program is running on. Since the real computer is invariably an imperative von Neumann machine, that runtime system has to be written imperatively. It is therefore an additional layer of abstraction between your program and the hardware.

     You could reverse your question : what toolkits are there, and which languauges do they support?

     For Example GTK : (from wikipedia)

     C GTK+ C++ gtkmm Ruby ruby-gtk2 Python PyGTK Java java-gnome .NET Gtk# PHP PHP-GTK Perl Gtk2-Perl

     You can find support for many languages if you explore these other widget toolkits :

     Juce — An extensive cross-platform UI toolkitFLTK — A light, cross platform, non-native widget toolkitFOX toolkit — A fast, open source, cross-platform widget toolkitGTK+ — The GIMP toolkit, a widget toolkit used by GNOME applicationsIUP_(software) -- IUP cross platform static/dynamic library C/LUA, Lua (MIT) licenceJX Application FrameworkMicrosoft Foundation Class - The most commonly used widgeting toolkit for Windows.MotifObject Windows Library & OWLNextQt — A widget toolkit used by KDEStandard Widget Toolkit — SWT for JavaSwing — Java widget toolkitTk — Toolkit part of the Tcl - project and often used by Perl and Python programmersUltimate++Visual Component LibrarywxWidgets — A free widget toolkitXForms

     Erlang, as described by Wikipedia:

     It was designed by Ericsson to support distributed, fault-tolerant, soft-real-time, non-stop applications.

     You might also want to read the Distributed Erlang section of their manual.

     However, note that Erlang is a functional language and will require a much different paradigm of thought as compared to C++.

   • programming languages Microsoft MPI support

     MS-MPI, based on MPICH with modifications, provides the MPI-standard C, C++ and Fortran interfaces.

     If you want Python (or Rust, or Julia, or whatever language you like), there are good 3rd party packages for that. MPI4PY ( is an excellent Python library for MPI, and works with lots of MPI implementations. See this question if you get stuck ( How to successfully compile mpi4py using MS HPC Server 2008 R2's MPI stack? ) but it sounds like nowadays mpi4py "just works".

     Legos make a good analogy here. MPI (any implementation) is like a big base plate. Maybe it's green, red, blue, but it's a standard foundation for "stuff". You don't have to use MS-MPI. you can use anything. mpi4py is a library. It provides the python routines and makes C mpi calls for you under the covers. mpi4py doesn't care (too much) about if it's plugged into a green base plate or a red one. the standard API allows this interoperability

     In your case, you want to make python calls. mpi4py will provide you python and make the MS-MPI calls for you. mpi4py by itself is kind of useless. It needs an MPI library. MS-MPI is a good MPI library for your platform. You'll need to set up MS-MPI first, then set up mpi4py. If you want to one day take your code somewhere else, you might need a different MPI library. Good news: the standard means swapping out MPI libraries (because you want to try something new or because you went to a different platform) is easy to do

     Have a look at Denotational semantics and operational semantics:

     Denotational semantics is an approach to formalizing the meanings of programming languages by constructing mathematical objects (called denotations) which describe the meanings of expressions from the languages.

     The operational semantics for a programming language describes how a valid program is interpreted as sequences of computational steps. These sequences then are the meaning of the program. In the context of functional programs, the final step in a terminating sequence returns the value of the program. (In general there can be many return values for a single program, because the program could be nondeterministic, and even for a deterministic program there can be many computation sequences since the semantics may not specify exactly what sequence of operations arrives at that value.)

   Declarative programming is when you write your code in such a way that it describes what you want to do, and not how you want to do it. It is left up to the compiler to figure out the how. Examples of declarative programming languages are SQL and Prolog.

   Code sample

   #myImageId {

   height: 100px;

   width: 100px;

   }

   Adam Bertram. What is declarative programming? Declarative programming is a method to abstract the control flow for logic required for software to perform an action. Instead, it involves stating what the task or desired outcome is. Declarative programming is a high-level programming concept, which is the opposite of imperative programming.
