Enhancing locality in Java based irregular applications
Faria, Nuno Filipe Monteiro; Silva, Rui C.; Sobral, João Luís FerreiraImproving locality of memory accesses in current and future multi-core platforms is a key to efficiently exploit those platforms. Irregular applications, which operate on pointer-based data structures, are hard to optimize in modern computer architectures due to their intrinsic unpredictable patterns of memory accesses. In this paper we explore a memory locality-driven set of data-structures in order to attenua...
Optimizing molecular dynamics simulations with product lines
Silva, Rui C.; Sobral, João Luís FerreiraThis paper presents a case study of using product-lines to address the variability of optimization methods and target platform mappings in high-performance molecular dynamics simulations. We use Feature Oriented Programming to incrementally extend the base algorithm by composing performance enhancement features with the core functionality. Developed features encapsulate common optimization methods in molecular ...
