In this video from the HPC Advisory Council Brazil Conference, DK Panda from Ohio State University presents: Designing Software Libraries and Middleware for Exascale Systems: Opportunities and Challenges.
“This talk will focus on challenges in designing software libraries and middleware for upcoming exascale systems with millions of processors and accelerators. Two kinds of application domains – Scientific Computing and Big data will be considered. For scientific computing domain, we will discuss about challenges in designing runtime environments for MPI and PGAS (UPC and OpenSHMEM) programming models by taking into account support for multi-core, high-performance networks, GPGPUs and Intel MIC. Features and sample performance numbers from MVAPICH2 and MVAPICH2-X (supporting Hybrid MPI and PGAS (UPC and OpenSHMEM)) libraries will be presented. For Big Data domain, we will focus on high-performance and scalable designs of Hadoop (including HBase) and Memcached using native RDMA support of InfiniBand and RoCE.”
