    Often, the simplest economic questions are the hardest to answer. Consider these: How much economic value did the massive decline in the cost of digitization in the last two decades create? And, would a similar level of decline in the next decade create the same amount of value? These are surprisingly difficult questions to answer. Obviously, large cost declines create new value. How much value? W... View full abstract»

    The rapid growth of online services in the last decade has led to the development of large data centers to host these workloads. These large-scale online, user-facing services have unique engineering and capacity provisioning design requirements. The authors explore these requirements, focusing on system balancing, the impact of technology trends, and the challenges of online service workloads. View full abstract»

    In this point-counterpoint discussion, Trevor Mudge argues for the combination of near-threshold voltage processors with techniques such as boosting to address the needs of datacenter workloads. Urs Hölzle offers a cautionary note on the wisdom of giving up too much single-threaded performance to achieve energy-efficiency in large Internet service applications. View full abstract»

    The authors argue that the minimum cost of computing can be provided by consolidating real-time workloads onto relatively large servers, which can operate at high utilization while maintaining required response time, and then filling the remaining overhead capacity with batch-like workloads sold at a significantly reduced price.

    Scale-out architectures supporting flexible, incremental scalability are common for computing and storage. However, the network remains the last bastion of the traditional scale-up approach, making it the data center's weak link. Through the UCSD Triton network architecture, the authors explore issues in managing the network as a single plug-and-play virtualizable fabric scalable to hundreds of th... View full abstract»

    Through the Datacenter Bridging task group, IEEE will add four supplements to the 802.1 standard that will both close the performance gap between Ethernet and InfiniBand and make the converged network a reality. In a converged network, all applications use a single physical infrastructure, which is ideal for the emerging next generation of data centers. View full abstract»

    Recent research has shown the potential benefits of subthreshold or near-threshold operation, which gives up a substantial degree of speed in order to reduce energy per operation. This is an excellent trade-off for many tasks, such as cyberphysical systems. This prolegomenon summarizes the benefits and challenges of subthreshold or near-threshold operation.
