At Google weve been longterm proponents of multi core architectures and throughputoriented computing In warehousescale systems throughput is more important than singlethreaded peak performance because no single processor can handle the full workload Clements M Frans Kaashoek Nickolai Zeldovich Robert T Morris and Eddie Kohler MIT CSAIL and Harvard University Abstract What fundamental opportunities for scalability are latent in interfaces such as system call APIs Can scalability opportunities b Andreas .
