In this podcast, the program co-chairs of the 2013 Hot Inteconnects Conference discuss how the annual symposium covers cross-cutting issues spanning computer systems, networking technologies, and communication protocols for high-performance interconnection networks. Program guests: Madeleine Glick (APIC Corporation) Torsten Hoefler (ETH Zurich) Fabrizio Petrini (IBM TJ Watson) Hot Interconnects takes place in San Jose, California […]
Over at The Register, Richard Chirgwin writes Australia’s CSIRO plans to use Geothermal cooling for a new petascale supercomputer. Located in bone-dry Perth, the system will be used to process data from the Square Kilometer Array Pathfinder (ASKAP) telescope. The water to cool the Pawsey machine will be drawn from an aquifer 100 meters below […]
Over at the Intel CSR blog, Lorie Wigle writes that replacing an old server with a more energy efficient design could save up to 1 ton of carbon emissions. Intel is also exploring other innovative and eco conscious technologies within its data centers. For example, on its Rio Rancho, New Mexico campus, Intel conducted a […]
In this video from the Adaptive Computing booth at SC12, Jenett Tillotson from Indiana University presents: Configuring Moab to Fairly Share a Supercomputer while Preventing Starvation in a University Setting.
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. […]
