Video: Datacenter Computers – Modern Challenges in CPU Design

Dick Sites, Senior Staff Engineer at Google

“Computers used as datacenter servers have usage patterns that differ substantially from those of desktop or laptop computers. We discuss four key differences in usage and their first-order implications for designing computers that are particularly well-suited as servers: data movement, thousands of transactions per second, program isolation, and measurement underpinnings. Maintaining high-bandwidth data movement requires coordinated design decisions throughout the memory system, instruction-issue system, and even instruction set.”

“The CMS detector at the Large Hadron Collider at CERN underwent a replacement of its data acquisition network to be able to process the increased data rate expected in the coming years. We will present the architecture of the system and discuss the design of its layers which are based on Infiniband as well as 10 and 40 GBit/s Ethernet.”

Video: Slim Fly – A Cost Effective Low-Diameter Network Topology

torsten

“We introduce a high-performance cost-effective network topology called Slim Fly that approaches the theoretically optimal network diameter. Slim Fly is based on graphs that approximate the solution to the degree-diameter problem. We analyze Slim Fly and compare it to both traditional and state-of-the-art networks. Our analysis shows that Slim Fly has significant advantages over other topologies in latency, bandwidth, resiliency, cost, and power consumption.”
