SUMMARY:InfiniBand, Omni-Path, and High-Speed Ethernet: Advanced Features,
  Challenges in Designing HEC Systems, and Usage
DESCRIPTION:Dhabaleswar Panda, Hari Subramoni, and Sourav Chakraborty (Ohi
 o State University)\n\nAs InfiniBand (IB), Omni-Path, and High-Speed Ether
 net (HSE) technologies mature, they are being used to design and deploy va
 rious High-End Computing (HEC) systems: HPC clusters with GPGPUs supportin
 g MPI, Storage and Parallel File Systems, Cloud Computing systems with SR-
 IOV Virtualization, Grid Computing systems, and Deep Learning systems. The
 se systems are bringing new challenges in terms of performance, scalabilit
 y, portability, reliability and network congestion. Many scientists, engin
 eers, researchers, managers and system administrators are becoming interes
 ted in learning about these challenges, approaches being used to solve the
 se challenges, and the associated impact on performance and scalability. \
 n\nThis tutorial will start with an overview of these systems. Advanced ha
 rdware and software features of IB, Omni-Path, HSE, and RoCE and their cap
 abilities to address these challenges will be emphasized. Next, we will fo
 cus on Open Fabrics RDMA and Libfabrics programming, and network managemen
 t infrastructure and tools to effectively use these systems. A common set 
 of challenges being faced while designing these systems will be presented.
  Case studies focusing on domain-specific challenges in designing these sy
 stems, their solutions and sample performance numbers will be presented. F
 inally, hands-on exercises will be carried out with Open Fabrics and Libfa
 brics software stacks and Network Management tools.\n\nTag: Advanced, Netw
