Domain-specific language compilers need to close the gap between the domain abstractions of the language and the low-level concepts of the target platform.This can be challenging to achieve for compilers targeting multiple platforms with potentially very different computing paradigms.In this paper, we present a multi-target, multi-paradigm DSL compiler for algorithmic graph processing. Our approach centers around an intermediate representation and reusable, composable transformations to be shared between the different compiler targets. These transformations embrace abstractions that align closely with the concepts of a particular target platform, and disallow abstractions that are semantically more distant. We report on our experience implementing the compiler and highlight some of the challenges and requirements for applying language workbenches in industrial use cases.
