Mapping parallel programs to heterogeneous CPU/GPU architectures using a Monte Carlo Tree Search

Mehdi Goli, John McCall, Christopher Brown, Vladimir Janjic, Kevin Hammond
2013 2013 IEEE Congress on Evolutionary Computation  
In this paper we describe a new technique that derives, automatically, optimal mappings for an application onto a heterogeneous architecture, using a Monte Carlo Tree Search algorithm.  ...  Additionally, with this increasing heterogeneity comes increasing complexity: not only does the programmer have to worry about where and how to express the parallelism, they must also express an efficient  ...  However, this is not the case for heterogeneous (CPU/GPU) architecture. There it is desirable to take advantage of GPU processing for suitable components when possible.  ...
