One of the most difficult problems to be solved by metacomputing systems is to ensure strong authentication and authorization. The problem is complicated since the hosts involved ...
With the advent of chip-multiprocessors (CMPs), Thread-Level Speculation (TLS) remains a promising technique for exploiting this highly multithreaded hardware to improve the perfo...
Metacomputing infrastructures couple multiple clusters (or MPPs) via wide-area networks. A major problem in programming parallel applications for such platforms is their hierarchi...
Abstract. With more cores integrated into one single chip, the overall power consumption from the multiple concurrent running programs increases dramatically in a CMP processor whi...
We propose a crossover operator that works with genetic programming trees and is approximately geometric crossover in the semantic space. By defining semantic as program’s eval...
