Multicore CPUs are beginning to appear in conventional desktop machines and laptop computers. Desktops with tens or hundreds of cores are not far off. One possible way to harness this power is to parallelize standard desktop applications such as the word processor or the web browser. Another possible way to harness the power is to parallelize the services offered by the operating system -- e.g., TCP processing -- and commonly- used library services -- e.g., secure http library functions). Which approach appears the most promising? Why?
