Slidecast: Advantages of Offloading Architectures for HPC

In this slidecast, Gilad Shainer from Mellanox describes the advantages of InfiniBand and the company’s off-loading network architecture for HPC. “The path to Exascale computing is clearly paved with Co-Design architecture. By using a Co-Design approach, the network infrastructure becomes more intelligent, which reduces the overhead on the CPU and streamlines the process of passing data throughout the network. A smart network is the only way that HPC data centers can deal with the massive demands to scale, to deliver constant performance improvements, and to handle exponential data growth.”

Call for Participation: hpc-ch Forum on Intra- and Inter-Site Networking

Using High Performance Interconnects in Dynamic Environments

“Over the last years the OFA community has shown the potential of using high performance networks (InfiniBand) to boost the performance of virtualized cloud environments, however, the network reconfiguration challenges still continue to exist. In this session we present the work we have been doing on InfiniBand subnet management and routing, in the context of dynamic cloud environments. This work includes, but not limited to, techniques in order to provide better management scalability when virtual machines are live migrating, tenant network isolation in multi-tenant environments, and fast performance-driven network reconfiguration.”

Video: InfiniBand as Core Network in an Exchange Application

“Group Deutsche Boerse is a global financial service organization covering the entire value chain from trading, market data, clearing, settlement to custody. While reliability has been a fundamental requirement for exchanges since the introduction of electronic trading systems in the 1990s, since about 10 years also low and predictable latency of the entire system has become a major design objective. Both issues have been important architecture considerations, when Deutsche Boerse started to develop an entirely new derivatives trading system T7 for its options market in the US (ISE) in 2008. As the best fit at the time a combination of InfiniBand with IBM WebSphere MQ Low Latency Messaging (WLLM) as the messaging solution was determined. Since then the same system has been adopted for EUREX, one of the largest derivatives exchanges in the world, and is now also extended to cover cash markets. The session will present the design of the application and its interdependence with the combination of InfiniBand and WLLM. Also practical experiences with InfiniBand in the last couple of years will be reflected upon.”

One Stop Systems 200TB Flash Storage Array SAN gets Rave Review

Today One Stop Systems announced the results of High-Tech Online Magazine Tom’s IT PRO’s review of the 200TB Flash Storage Array SAN (FSA-SAN). OSS’ FSA-SAN provides 200TB of shared Flash RAIDed memory with a choice of the fastest SAN connectivity options including Fiber Channel, Infiniband, and iSCSI.

Video: Software-Defined Networking on InfiniBand Fabrics

A design for virtual Ethernet networks over IB is described. The virtual Ethernet networks are implemented as overlays on the IB network. They are managed in a flexible manner using software. Virtual networks can be created, removed, and assigned to servers dynamically using this software. A virtual network can exist entirely on the IB fabric, or it can have an uplink connecting it to physical Ethernet using a gateway. The virtual networks are represented on the servers by virtual network interfaces which can be used with para-virtualized I/O, SRIOV,and non-virtualized I/O. This technology has many uses: communication between applications which are not IB-aware, communication between IB-connected servers and Ethernet-connected servers, and multi-tenancy for cloud environments. It can be used in conjunction with OpenStack, such as for tenant networks.”

Live Report from LUG 2016 Day 2

In this special guest feature, Ken Strandberg offers this live report from Day 2 of the Lustre User Group meeting in Portland. “Scott Yockel from Harvard University shared how they are deploying Lustre across their massive three data centers up to 90 miles apart with 25 PB of storage, about half of which is Lustre. They’re using Docker containers and employing a backup strategy across the miles of every NFS system, parsing of the entire MDT, and includes 10k directories of small files.”

Video: Past, Present, and Future of OpenFabrics Interfaces

“The first release of OpenFabrics Interfaces (OFI) software, libfabric, occurred in January of 2015. Since then, the number of fabrics and applications supported by OFI has increased, with considerable industry momentum building behind it. This talk discusses the current state of OFI, then speaks to the application requirements driving it forward. It will detail the fabrics supported by libfabric, identify applications which have ported to it, and outline future enhancements to the libfabric interfaces and architecture.”

University of New Orleans Wins Silicon Mechanics Research Cluster Grant

Today Silicon Mechanics announced that the University of New Orleans is the recipient of the company’s fifth annual Research Cluster Grant (RCG). Each grant awardee will receive a High-Performance Computing cluster with the latest high-performance processing and GPU technologies, valued at over $100,000 for use in demonstrated research purposes going forward. This is the second year that Silicon Mechanics has made the award to two institutions.
