Abstract

The last few years has seen activity towards programming models, languages and frameworks to address the increasingly wide range and broad availability of heterogeneous computing resources through raised programming abstraction and portability across different platforms.

The effort spent in simplifying parallel programming across heterogeneous platforms is often outweighed by the need for low-level control over computation setup and execution and by performance opportunities that are often missed due to the overhead introduced by the additional abstraction. Moreover, despite the ability to port parallel code across devices, each device is generally characterised by a restricted set of computations that it can execute outperforming the other devices in the system. The problem is therefore to schedule computations on increasingly popular multi-device heterogeneous platforms, helping to choose the best device among the available ones each time a computation has to execute.

FSCL in an infrastructure to develop and execute parallel computations in F# from within the .NET environment. Its purpose is to efficiently address the problem of programming abstraction on heterogeneous platforms while helping to dynamically exploit the computing power of such platforms at runtime through a transparent scheduling strategy based on algorithmic feature extraction and classification.
