- Title
Efficient High-Level Programming in Plain Java.

Silva, Rui S.; Sobral, João L.
- Abstract
This paper introduces the support for developing efficient parallel programs in plain Java in the Gaspar framework. The framework supports a complete set of data locality optimisations that are introduced with Java annotations, keeping the original Java code platform independent and postponing performance tuning tasks. Performance results show that data layout improvements can provide a 2.5-fold speedup, and, when combined with the exploitation of parallelism, can deliver a 50-fold speedup when compared with an unoptimised sequential base Java application running on a 24-core machine.
