In this talk, we introduce the rCUDA remote GPU virtualization framework, which has been shown to be the only one that supports the most recent CUDA versions, in addition to leverage the InfiniBand interconnect for the sake of performance. Furthermore, we also present the last developments within this framework, related with the use of low-power processors, enhanced job schedulers, and virtual machine environments.”
“Congratulations go out to Troy Baer, HPC system administrator at the National Institute for Computational Sciences (NICS), University of Tennessee. Troy Baer’s contributions in scheduling and resource management using Moab have helped Kraken—NICS’ flagship computing resource and the first academic computer to break the petaflop barrier—achieve outstanding 90-95% utilization rates since 2010. Baer’s administrative capabilities enable researchers in numerous scientific arenas, from climate to materials science to astrophysics, to achieve breakthroughs not yet possible on other resources. In November 2012, Baer helped NICS’ Beacon system secure a No. 1 ranking on the Green500 list of energy-efficient supercomputers.”
“This talk will focus on programming models and their designs for upcoming exascale systems with millions of processors and accelerators. Current status and future trends of MPI and PGAS (UPC and OpenSHMEM) programming models will be presented. We will discuss challenges in designing runtime environments for these programming models by taking into account support for multi-core, high-performance networks, GPGPUs, Intel MIC, scalable collectives (multi-core-aware, topology-aware, and power-aware), non-blocking collectives using Offload framework, one-sided RMA operations, schemes and architectures for fault-tolerance/fault-resilience.”
Arista Networks filed for an initial public offering today. Founded by Andy Bechtolsheim, Arista builds switches that handle traffic at large internet data centers for companies including Facebook Inc, Yahoo Inc, Comcast Corp and Citigroup Inc. The company said it would raise $200 million from the offering, but the final size of the IPO could vary.
In this video from GTC 2014, Steve Oberlin from Nvidia describes his new role as Chief Technical Officer for Accelerated Computing. Along the way, he discusses: the HPC lessons learned from the CRAY T3E and other systems, Nvidia’s plans to tackle the challenges of the HPC Memory Wall, the current status on Project Denver, and how Nvidia plans to couple to the POWER architecture in future systems.
