The Challenge of Complexity and Scale
نویسنده
چکیده
Systems built from commodity processors dominate high-performance computing today, with systems containing thousands of processors now being deployed. Moreover, we face new challenges from processor power budget limits, shrinking transistor feature sizes, and intra-chip parallelism. As node counts for multi-teraflop systems grow to tens of thousands, with proposed petaflop system likely to contain hundreds of thousands of nodes, and with a tsunami of new experimental and computational data ahead, we must rethink traditional assumptions about software scaling and manageability and hardware reliability.

The roles and effects of changes in syntax on comprehension and processing effort, and the relationships between these two, comprise a large and separate field of inquiry, with the general belief now in place that such changes and variations bring about varied psycholinguistic and discursive implications for comprehension, manifesting themselves differently in different genres.The current study...
متن کاملUsing Complexity to Simplify Knowledge Translation; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
Putting health theories, research and knowledge into practice is a challenge referred to as the knowledge-toaction gap. Knowledge translation (KT), and its related concepts of knowledge mobilization, implementation science and research impact, emerged to mitigate this gap. While the social interaction view of KT has gained currency, scholars have not easily made a link between KT and the concep...
