In this video from the Adaptive Computing booth at SC12, Dr. Bastian Koller from the HLRS HPC Center in Stuttgart presents: Realizing Energy Efficient Scheduling in a Network of Data Centers.
Penguin Computing, experts in high performance computing (HPC) solutions, made three announcements today: AOL Moves Micro Data Centers (MDCs) Powered by Penguin Computing Into Production: AOL’s MDCs are small ‘Data Centers in a Box’. There are two MDC versions: one for outdoor, one for indoor use. Each MDC unit is self sufficient and includes high […]
Over at The Register, Dan Olds discusses the massive power & cooling requirements at Oak Ridge National Lab with Arthur “Buddy” Bland. Findo out how ORNL manages to achieve a remarkable Power Usage Effectiveness (PUE) score of 1.25 and how they continue to push for even greater energy efficiency.
In this video, Michael R. Watts from MIT presents: Electronic-Photonic Integration within Switches and Routers. We review recent successes in silicon photonics and how the new capabilities afforded by silicon photonics will impact future Ethernet, Infiniband, and ultimately optical domain switches and routers. Specifically, we consider the impact silicon photonics can have on the cost, […]
In this video, Hans Eberle from Oracle Labs presents: Weighted Differential Scheduler. The Weighted Differential Scheduler (WDS) is a new scheduling discipline for accessing shared resources. The work described here was motivated by the need for a simple weighted scheduler for a network switch where multiple packet flows are competing for an output port. The […]
In this video, Radia Perlman from Intel presents: How to Compare Alternative Architectures. There are various aspects of network infrastructure that are orthogonal, and therefore can be compared conceptually. For example, the syntax of encapsulation, how forwarding tables are calculated, and whether forwarding tables are filled in proactively, or on-demand when a new flow starts. […]
Got Exascale ideas? In this video, Thomas Ndousse-Fetter from the DoE Department of Science announces a Call for Participation in the Small Business Innovation Research and Small Business Technology Transfer programs (SBR/STTR). The programs are designed for small businesses that want to get involved in the Exascale technology development ecosystem. Recorded at the Hot Interconnects […]
In this video, Fuad Doany from IBM T. J. Watson presents: Power-Efficient, High-Bandwidth Optical Interconnects for High Performance Computing. High performance computing systems are driving development and large-scale deployment of parallel optical interconnects to meet the ever-increasing interconnect bandwidth requirements. We have demonstrated generations of chip-scale transceivers, or “Optochips”, with record setting high-speed, high-density, and […]
Over at EE Times, Rick Merritt writes that interconnects are the newest front in the war over server microprocessors between Intel and ARM. Intel is widely expected to implement in future Xeon processors the interconnect technology from a spate of recent acquisitions. Server and adapter makers believe such a move could narrow their hardware options […]
In this video, Jerome Vienne from Ohio State University presents: Performance Analysis and Evaluation of InfiniBand FDR and 40GigE RoCE on HPC and Cloud Computing Systems. In this paper, we evaluate various high performance interconnects over the new PCIe Gen3 interface with HPC as well as cloud computing workloads. Our comprehensive analysis, done at different […]
