Treffer: SAC—A Functional Array Language for Efficient Multi-threaded Execution.

We give an in-depth introduction to the design of our functional array programming language S aC, the main aspects of its compilation into host machine code, and its parallelisation based on multi-threading. The language design of S aC aims at combining high-level, compositional array programming with fully automatic resource management for highly productive code development and maintenance. We outline the compilation process that maps S aC programs to computing machinery. Here, our focus is on optimisation techniques that aim at restructuring entire applications from nested compositions of general fine-grained operations into specialised coarse-grained operations. We present our implicit parallelisation technology for shared memory architectures based on multi-threading and discuss further optimisation opportunities on this level of code generation. Both optimisation and parallelisation rigorously exploit the absence of side-effects and the explicit data flow characteristic of a functional setting. [ABSTRACT FROM AUTHOR]
