OpenPOWER Academic Discussion Group Workshop Promotes Collaboration

Blogs


The OpenPOWER Foundation’s Academic Discussion Group hosted its 5th annual workshop on November 6, 2020.

The annual event is intended to facilitate interaction and engagement between Academic institutions, with a focus on supporting developers from different application areas of scientific computing, data analytics and artificial intelligence.

The 2020 workshop was hosted by Dirk Pleiter of the Jülich Supercomputing Centre, Ganesan Narayanasamy of IBM, Sameer Shende of the University of Oregon and Fabrizio Magugliani of E4 Computer Engineering.

A summary of the content shared at the event is included below.

Extreme-scale Scientific Software Stack

  • The DOE Exascale Computing Project Software Technology focus area is developing an HPC software ecosystem that will enable the efficient and performant execution of exascale applications.

LBM performance in Exascale era

  • In the next two years, the first Exascale class supercomputers will be delivered. In this talk, starting from the results obtained using Marconi100, we try to extrapolate a reasonable performance scenario that a Lattice Boltzmann Method (LBM) based code can achieve using these high-end HPC machines.

Exploring the Power of Containerization to Improve Data – and HPC-Education

  • Hands-on learning over big data sets is complicated by several factors including data movement, bandwidth consumption. To understand the analytics at scale, students need a uniform learning environment to fulfill their learning needs on top of multiple different infrastructures starting from their personal laptop to different types of high-performance computing cluster. This presentation demonstrates how ‘Onstitute’ addresses this issue utilizing the power of containerization on top of cutting edge HPC-technologies such as, POWER-based hardware.

Memory is everywhere and… is often the bottleneck

  • The POWER9 processor brought the OpenCapi interface which provides a huge bandwidth and very low latency to systems, but also keeps the data coherency. This standard is used by hardware accelerators to off-load applications bringing dedicated optimized processing to servers, but also to manage all new technology host memory types. This presentation includes real use cases to show its amazing capabilities through huge data acquisition chain used in synchrotron.

FPGA acceleration of Spark SQL queries using Apache Arrow and OpenCAPI

  • Apache Spark is one of the most widely used big data analytics frameworks due to its user-friendly API. However, the high level of abstraction in Spark introduces large overheads to access modern high-performance heterogeneous hardware accelerators such as FPGAs. This talk discusses solutions to accelerate Spark SQL queries using FPGAs and to offload these computations transparently with little user configuration.

Disaggregated memory technologies and future opportunities in the HPC world

  • Traditional server trays encapsulate memory, computational units and accelerators creating physical constraints that limit clusters design flexibility. But, for what concerns memory, this is not the only option anymore. This talk explores how disaggregated memory technologies bring future opportunities in HPC scenarios.
