Apache Mahout's code abstracts the domain specific language from the engine where the code is run. While active development is done with the Apache Spark engine, users are free to implement any engine they choose- H2O and Apache Flink have been implemented in the past and examples exist in the code base.

Commercial implementations are either general purpose or tied to specific hardware by a vendor. Examples of general purpose languages include: AccelerEyes' Jacket, a commercialization of a GPU engine for MATLAB; Ateji PX Java extension that enables a simple expression of stream programming, the Actor model, and the MapReduce algorithm
Credit card debt can feel like getting mired in quicksand. You make some purchases or take small steps forward, and before you know it, you’re stuck.
