UD professor works to overcome challenges in harnessing power of multicore computer processors

Computer processors that can complete multiple tasks simultaneously have been available in the mainstream for almost a decade. In fact, almost all processors developed today are multicore processors. Yet, computer programmers still struggle to efficiently harness their power because it is difficult to write correct and efficient parallel code.

According to the University of Delaware’s John Cavazos, to effectively exploit the power of multi-core processors, programs must be structured as a collection of independent tasks where separate tasks are executed on independent cores.

The complexity of modern software, however, makes this difficult. (more…)

Homeland Security Chief Speaks About Challenges Facing U.S., Global Cooperation

The United States is stronger and more secure than it was prior to 9/11, but threats from overseas remain and must be proactively managed, said Secretary of Homeland Security Janet Napolitano, who visited campus April 16 for a public talk sponsored by the UCLA Burkle Center for International Relations.

In a globalized world, international cooperation is the key to identifying those who intend to do harm, she said, adding that threats to the global supply chain, the activities of drug and human smuggling organizations, and the prevalence of cyber-criminals who attempt to steal information and intellectual property and disrupt critical networks are among the major challenges facing the Department of Homeland Security.
