Automatic Task-Based Code Generation for High Performance Domain Specific Embedded Language

摘要

Providing high level tools for parallel programming while sustaining a high level of performance has been a challenge that techniques like Domain Specific Embedded Languages try to solve. In previous works, we investigated the design of such a DSEL-NT~2-providing a MATLAB -like syntax for parallel numerical computations inside a C++ library. In this paper, we show how NT~2 has been redesigned for shared memory systems in an extensible and portable way. The new NT~2 design relies on a tiered Parallel Skeleton system built using asynchronous task management and automatic compile-time taskification of user level code. We describe how this system can operate various shared memory runtimes and evaluate the design by using two benchmarks implementing linear algebra algorithms.
