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.
[1]Development of Split-C appears to be at a standstill since 1996.
Split-C is similar to Cilk.
