The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP), is resuming the webinar series on Best Practices for HPC Software Developers, which we began last year.
As part of this series, we will offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. Participation is free and open to the public, but registration will be required for each event.
The next webinar in the series was “Using the Roofline Model and Intel Advisor” with speaker Sam Williams of Lawrence Berkeley National Laboratory. This webinar took place on August 16, 2017 and you can find a copy of the presentation and the video from the webinar in the Presentation Materials section below.

The next webinar is titled “Barely Sufficient Project Management: A few techniques for improving your scientific software development efforts”, and will be presented by Michael Heroux of Sandia National Laboratories.
Software development is an essential activity for many scientific teams. Modeling, simulation and data analysis, using team-developed software, are increasing valuable for scientific discovery and engineering. Many teams use informal, ad hoc approaches for managing their software efforts. While sufficient for many efforts, a modest emphasis on team models and processes can substantially improve developer productivity and software sustainability.
In this presentation, we discuss several light-weight techniques for managing scientific software efforts. Using checklists, policy statements and a Kanban workflow system, we emphasize techniques for managing the initiation and exit of team members, approaches to synthesizing team culture, and ways to improve communication within a team and with its stakeholders.

The DOE Exascale Computing Project (ECP) is pleased to sponsor a webinar presented by Michael Wolfe of NVIDIA titled “Scalable Node Programming with OpenACC” that took place on Wednesday, September 20, at 1:00 pm ET.
Supercomputer nodes are becoming more parallel with each generation. HPC applications must now utilize parallelism on-node as well as across many nodes for performance. OpenACC is designed to expose and exploit parallelism, whether that be for a multicore, a manycore, or a GPU-accelerated node.
This webinar discussed:
- what problems OpenACC addresses;
- the important elements of OpenACC;
- how and why OpenACC is being adopted and used in production science and engineering applications, including Gaussian, Fluent, VASP, and several weather and climate codes;
- current status of OpenACC tools and of the specification;
- building and using applications with OpenACC for different targets;
- the OpenACC community and user events;
- new features requested by users coming with OpenACC 2.6 and beyond.

The next webinar in the series was titled “Managing Defects in HPC Software Development”, and was be presented by Dr. Tom Evans of the Oak Ridge National Laboratory and PI of the ECP Application Development Project titled, Coupled Monte Carlo Neutronics and Fluid Flow Simulation of Small Modular Reactors (ExaSMR). The webinar took place on Wednesday, November 1, at 1:00 pm ET.
Software Quality Engineering (SQE) and methods research and scientific investigation are often thought to be incompatible. However, in reality they are not only compatible, but required in order to have confidence in the results of even basic scientific computations. This is especially true for parallel software. In this talk we will look at methods for performing software verification. Software verification is a method for removing defects at code construction time; these techniques can help in both algorithm and method development, as well as increased productivity.

The next webinar in the series took place on December 6, 2017 and was titled “Better Scientific Software”.
Better Scientific Software (BSSw) is an organization dedicated to improving developer productivity and software sustainability for computational science and engineering (CSE). This presentation introduced a new website (https://bssw.io)—a community exchange for scientific software improvement. We’re creating a clearinghouse to gather, discuss, and disseminate experiences, techniques, tools, and other resources to improve software productivity and sustainability for CSE. Site users can find information on scientific software topics and can propose to curate or create new content based on their own experiences. The backend enables collaborative content development using standard GitHub tools and processes. We need your contributions to build the BSSw site into a vibrant resource, with content and editorial processes provided by volunteers throughout the international CSE community.

The next webinar in the series was titled “Bringing Best Practices to a Long-Lived Production Code“, and was presented by Dr. Charles R. Ferenbaugh of Los Alamos National Laboratory. The webinar took place on Wednesday, January 17, 2018 at 1:00 pm ET.
Abstract:
How can you introduce best software practices to a long-lived scientific production code, with a significant user base, that has “gotten along fine” for years doing things its own way? Often developers in such projects must struggle with overly complex code, inadequate documentation, little or no software process, and a “just write the code fast” culture; these are challenges to software quality that are generally not issues for new projects. In this presentation the speaker discussed some of the peculiar problems faced by long-lived codes, and present a case study of how they are dealing with these issues in the xRage code at LANL.

Abstract:
During the last few years the Jupyter notebook has become one of the tools of choice for the data science and high-performance computing (HPC) communities. This webinar will provide an overview of why Jupyter is gaining traction in education, data science, and HPC, with emphasis on how notebooks can be used as interactive documents for exploration and reporting. We will present an overview of how Jupyter works and how the network protocol can be leveraged for both a local single machine and remote-cluster work. We will discuss the nuts and bolts of how Jupyter has been deployed at NERSC as a case study in implementation of Jupyter in an HPC environment. This work implies learning the Jupyter ecosystem to take advantage of its powerful abstractions to develop custom infrastructure to satisfy policies and user needs. The webinar showed, as a use case, how Jupyter notebooks have transformed data discovery, visualization, and interactive analysis for the scanning probe and electron microscopy communities at Oak Ridge National Laboratory. It also showed how notebooks can seamlessly accommodate measurements from a wide variety of instruments through Pycroscopy, a framework for instrument agnostic data storage and analysis.
