Multi-network MPI on Intel Omni-Path

Networks

As part of the NEXTGenIO project we have a prototype HPC system that has two Intel Omni-Path networks attached to each node. The aim of having a dual-rail network setup for that system is to investigate the performance and functionality benefits of having separate networks for MPI communications and for I/O storage communications, either directing Lustre traffic and MPI traffic over separate networks, or using a separate network to access NVDIMMs over RDMA. We were also interested in the performance benefits for general applications exploiting multiple networks for MPI traffic, if and where possible.

Guest blogger Simon Chapple introduces the University of Edinburgh's IoT Research and Innovation Service.

Most people will have heard of the Internet of Things (IoT). It is a hot topic in technology, business and the mainstream news, projected as it is to underpin a future trillion-dollar market at least as large as, and by some estimations even greater than, the cloud-based computing services industry. We define IoT as a network of dedicated physical objects that contain embedded technology to sense and interact with the external environment, and that can connect and exchange data.

Giuseppe Negro undertook an HPC-Europa3 visit based in Edinburgh from 15/04/19–27/05/19. He gives us a brief overview of his visit and the work he undertook.

Hi everyone! My name is Giuseppe Negro and I am a PhD student at the University of Bari in Italy. I work in computational modelling of soft matter systems with Prof. Giuseppe Gonnella and with my collegue Livio Nicola Carenza, who was also an HPC-Europa3 visitor in Edinburgh, at the Department of Physics in Bari. I visited EPCC under the HPC-Europa3 transnational access programme, and I was hosted by Prof. D. Marenduzzo at the Department of Physics and Astronomy of the University of Edinburgh located at the James Clerk Maxwell Building.

The EU VESTEC research project is focused on the use of HPC for urgent decision-making and the project team will be running a workshop at SC’19.

VESTEC will build a flexible toolchain to combine multiple data sources, efficiently extract essential features, enable flexible scheduling and interactive supercomputing, and realise 3D visualisation environments for interactive explorations.

Widening access to HPC for Europe’s SMEs

The SHAPE programme, led by EPCC, has helped over 40 companies across Europe to get a foot on the HPC ladder, with benefits including reduced costs and faster time to market.

SHAPE was set up to raise awareness of high-performance computing (HPC) among European SMEs (small and medium-sized enterprises) and to provide them with the expertise required to take advantage of the innovation possibilities created by HPC. The ultimate aim of the programme is to increase the competitiveness of SMEs in Europe.
