Enquadramento
Java 9 will implement GPU offloading of intense stream computations. This is being worked under the codename of Project Sumatra.
http://openjdk.java.net/projects/sumatra/
One of the challenges is to known when to offload an operation or not. This has been tackled in a Java-based Map-Reduce framework.

Objetivo
The main goal of this thesis is to explore and develop a decision mechanism between GPU and CPUs to be included in the next version of Java.
This goal can be achieved through the following objectives:
- Study of the state of the art in platform decision.
- Development of a decision point inside the existing JDK, allowing for several plug-in mechanism decisions to be used.
- Development of a few different new heuristic mechanisms.
- Development of a mechanism that makes usage of machine-learning techniques.
- Evaluation of all mechanisms on a medium-sized benchmark suite.

Observações
We are looking for a T-shaped student: he or she should be highly competent in systems programming in Java and knowledge of Machine Learning techniques. A good understanding of parallel and concurrent programming is also a must.
