Designing High-End Computing Systems with InfiniBand and High-Speed Ethernet
SESSION: Designing High-End Computing Systems with InfiniBand and High-Speed Ethernet
EVENT TYPE: Tutorials
TIME: 1:30PM - 5:00PM
Presenter(s):Dhabaleswar K. (DK) Panda, Hari Subramoni
As InfiniBand (IB) and High-Speed Ethernet (HSE) technologies mature, they are being used to design and deploy different kinds of High-End Computing (HEC) systems: HPC clusters with accelerators (GPGPUs and MIC) supporting MPI and PGAS (UPC and OpenSHMEM), Storage and Parallel File Systems, Cloud Computing systems with Hadoop (HDFS, MapReduce and HBase), Multi-tier Datacenters with Web 2.0 (memcached) and virtualization, and Grid Computing systems. These systems are bringing new challenges in terms of performance, scalability, portability, reliability and network congestion. Many scientists, engineers, researchers, managers and system administrators are becoming interested in learning about these challenges, approaches being used to solve these challenges, and the associated impact on performance and scalability. This tutorial will start with an overview of these systems and a common set of challenges being faced while designing these systems. Advanced hardware and software features of IB and HSE and their capabilities to address these challenges will be emphasized. Next, case studies focusing on domain-specific challenges in designing these systems (including the associated software stacks), their solutions and sample performance numbers will be presented. The tutorial will conclude with a set of demos focusing on RDMA programming, network management infrastructure and tools to effectively use these systems.
