Io is a pure object-oriented programming language inspired by Smalltalk, Self, Lua, Lisp, Act1, and NewtonScript. Io has a prototype-based object model similar to the ones in Self and NewtonScript, eliminating the distinction between instance and class. Like Smalltalk, everything is an object and it uses dynamic typing. Like Lisp, programs are just data trees. Io uses actors for concurrency.

Squirrel is a high level imperative, object-oriented programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games. MirthKit, a simple toolkit for making and distributing open source, cross-platform 2D games, uses Squirrel for its platform. It is used extensively by Code::Blocks for scripting and was also used in Final Fantasy Crystal Chronicles: My Life as a King It is also used in Left 4 Dead 2 and Portal 2 for scripted events.

Treelang is a "toy" programming language distributed with the GNU Compiler Collection (GCC) to demonstrate the features of its code-generation backend. It was developed by Tim Josling, based on a language called Toy created by Richard Kenner. During the GCC 4.3 release cycle, a patch was committed to remove the language, because of high maintenance costs outweighing its benefits and also because it was no longer considered a good front-end example by GCC developers.

OpenMP (Open Multi-Processing) is an API (Application Programming Interface) that supports multi-platform shared memory multiprocessing programming in C, C++, and Fortran, on most processor architectures and operating systems, including Linux, Unix, AIX, Solaris, Mac OS X, and Microsoft Windows platforms. It consists of a set of compiler directives, library routines, and environment variables that influence run-time behavior.

HMPP for Hybrid Multicore Parallel Programming. Based on a set of directives, OpenHMPP Standard is a programming model designed to handle hardware accelerators without the complexity associated with GPU programming. This approach based on directives has been implemented because they enable a loose relationship between an application code and the use of a hardware accelerator.

Oak was a programming language created by James Gosling in 1991, initially for Sun Microsystems set-top box project. The language later evolved to become Java. The name Oak was used by Gosling after an oak tree that stood outside his office.

Sing# is a concurrent programming language that is a superset of the Spec# programming language; in turn, Spec# is an extension of the C# programming language. Microsoft Research developed Spec#, and later extended it into Sing# in order to develop the Singularity operating system. Sing# augments the capabilities of Spec# with support for channels and low-level programming language constructs, which are necessary for implementing system software. Sing# is type-safe. The semantics of message-passing primitives in Sing# are defined by formal and written contracts.

SAC (Single Assignment C) is a strict purely functional programming language which design is focused on the needs of numerical applications. Emphasis is laid on efficient support for array processing. Efficiency concerns are essentially twofold. On the one hand, efficiency in program development is to be improved by the opportunity to specify array operations on a high level of abstraction. On the other hand, efficiency in program execution, i.e. the runtime performance of programs, in time and memory consumption, is still to be achieved by sophisticated compilation schemes. Only as far as the latter succeeds, the high-level style of specifications can actually be called useful.

Split-C is a parallel extension of the C programming language. The Split-C project website describes Split-C as: a parallel extension of the C programming language that supports efficient access to a global address space on current distributed memory multiprocessors. It retains the "small language" character of C and supports careful engineering and optimization of programs by providing a simple, predictable cost model.

Cg (short for C for Graphics) is a high-level shading language developed by Nvidia in close collaboration with Microsoft for programming vertex and pixel shaders. It is very similar to Microsoft's HLSL.
