Robert Harrison from Brookhaven gave this talk at the MVAPICH User Group. “MADNESS, TESSE/EPEXA, and MolSSI are three quite different large and long-lived projects that provide different perspectives and driving needs for the future of message passing. All three of these projects employ MPI and have a vested interest in computation at all scales, spanning the classroom to future exascale systems.”

Video: High-Performance Computing with Python – Reducing Bottlenecks
August 11, 2019 by
This course addresses scientists with a working knowledge of NumPy who wish to explore the productivity gains made possible by Python for HPC. “We will show how Python can be used on parallel architectures and how to optimize critical parts of the kernel using various tools. The following topics will be covered: – Interactive parallel programming with IPython – Profiling and optimization – High-performance NumPy – Just-in-time compilation with Numba – Distributed-memory parallel programming with Python and MPI – Bindings to other programming languages and HPC libraries – Interfaces to GPUs.”
Multiple Endpoints in the Latest Intel MPI Library Boosts Hybrid Performance
July 24, 2019 by
The performance of distributed memory MPI applications on the latest highly parallel multi-core processors often turns out to be lower than expected. Which is why hybrid applications using OpenMP multithreading on each node and MPI across nodes in a cluster are becoming more common. This sponsored post from Intel, written by Richard Friedman, depicts how to boost performance for hybrid applications with multiple endpoints in the Intel MPI Library.

July 20, 2019 by
In this video from PASC19, Torsten Hoefler from ETH Zurich describes how PASC19 has grown into an international conference with over 60 percent of attendees from outside Switzerland. After that, he describes a new groundbreaking programming model his team is developing that centers around the minimization of data movement for computation.
Achieving Parallelism in Intel Distribution for Python with Numba
July 11, 2019 by
The rapid growth in popularity of Python as a programming language for mathematics, science, and engineering applications has been amazing. Not only is it easy to learn, but there is a vast treasure of packaged open source libraries out there targeted at just about every computational domain imaginable. This sponsored post from Intel highlights how today’s enterprises can achieve high levels of parallelism in large scale Python applications using the Intel Distribution for Python with Numba.
The Challenges of Updating Scientific Codes for New HPC Architectures
July 10, 2019 by
In this video from PASC19 in Zurich, Benedikt Riedel from the University of Wisconsin describes the challenges researchers face when it comes to updating their scientific codes for new HPC architectures. After that he describes his work on the IceCube Neutrino Observatory.
Video: Data-Centric Parallel Programming
July 8, 2019 by
In this slidecast, Torsten Hoefler from ETH Zurich presents: Data-Centric Parallel Programming. “To maintain performance portability in the future, it is imperative to decouple architecture-specific programming paradigms from the underlying scientific computations. We present the Stateful DataFlow multiGraph (SDFG), a data-centric intermediate representation that enables separating code definition from its optimization.”

June 27, 2019 by
Whatever the platform, getting the best possible performance out of an application always presents big challenges. This is especially true when developing AI and machine learning applications on CPUs. This sponsored post from Intel explores how to effectively train and execute machine learning and deep learning projects on CPUs.
Video: Portable Programming Models Highlighted at PASC19
June 15, 2019 by
In this video from PASC19 in Zurich, Technical Papers co-chair Sunita Chandrasekaran provides some highlights from the conference. After that, Sunita previews the upcoming Workshop on Performance Portable Programming Models for Accelerators (P3MA) at ISC 2019. “This workshop will provide a forum to bring together researchers and developers to discuss community’s proposals and solutions to performance.”
