The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which we began in 2016.
As part of this series, we offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. The August webinar is titled Software Engineering Challenges and Best Practices for Multi-Institutional Scientific Software Development, and will be presented by Keith Beattie (Lawrence Berkeley National Laboratory). The webinar will take place on Wednesday, August 4, 2021 at 1:00 pm ET.
Abstract:
Scientific software is increasingly becoming the backbone of obtaining and validating scientific results. This is no longer just the case for traditionally computationally intensive areas but is now true across a wide variety of scientific disciplines. This circumstance elevates how scientific software is developed, independent of the field, to a new level of importance. Further, the multi-institutional nature of many science projects presents unique challenges to how scientific software can be effectively developed and maintained over the long term. In this webinar we present the challenges faced in leading the development of scientific software across a distributed, multi-institutional team of contributors, and we describe a set of best-practices we have found to be effective in producing impactful and trustworthy scientific software.

What is Variorum?
Variorum is a production-grade, open-source, vendor-neutral software infrastructure for exposing low-level control and monitoring of a system’s underlying hardware features. It can easily be ported to different hardware devices, as well as different generations within a particular device. This allows users to manage power, performance and thermal information seamlessly across hardware from different vendors. More specifically, Variorum’s flexible design supports a set of features that may exist on one generation of hardware, but not on another. Variorum can also be included as part of the system software stack for power management: such as runtime systems, resource managers, and other profiling tools. At present, Variorum supports 5 platforms (IBM, Intel, AMD, ARM and NVIDIA) and a total of ten microarchitectures across these platforms.

Module 1
Module 2
The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which we began in 2016.
As part of this series, we offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. The September webinar is titled What I Learned from 20 Years of Leading Open Source Projects, and will be presented by Wolfgang Bangerth (Colorado State University). The webinar will take place on Wednesday, September 15, 2021 at 2:00 pm ET. This webinar will start one hour later than the usual time.
Abstract:
Scientific software has grown from loose collections of individual routines working on relatively simple data structures to very large packages of 100,000s to millions of lines of code, with dozens of contributors, and hundreds or thousands of users. In the process, the approaches to software development have also drastically changed: both the software packages as well as their development are professionally managed, with version control, extensive test suites, and automatic regression checks for every patch. Maybe more interestingly, the approaches to managing the *community* of software developers and users have also dramatically changed.
Having led two large, open source software projects (the finite element package deal.II, and the Advanced Simulator for Problems in Earth ConvecTion ASPECT) for more than 20 years, the presenter will share lessons learned about both the technical management of scientific software projects, as well as the social side of these projects.
In response to the COVID-19 pandemic and transition to remote work, ECP and the IDEAS Productivity project launched the panel series Strategies for Working Remotely, which explores important topics in this area.
Abstract:
- Many organizations abruptly transitioned from a primarily on-site to a primarily remote work experience last spring. However, organizations still have training needs that were once largely accomplished through in-person events such as workshops, hackathons, and tutorials. This panel shared what they learned during the past year in their efforts to bring more virtualization to what historically has worked for in-person training events. What worked well? What did not work? This panel shared their insights about lessons learned over the past year and how those experiences will inform plans moving forward when organizations can safely offer in-person training again.
Panelists:
- Kelly Barnes, The Carpentries
- Helen He, NERSC, Lawrence Berkeley National Laboratory
- Julia Levites, Nvidia Corporation
- Thomas Papatheodore, OLCF, Oak Ridge National Laboratory
Moderators:
- Ashley Barker, Oak Ridge National Laboratory
- Osni Marques, Lawrence Berkeley National Laboratory

2021 HDF5 User Group Meeting
The 2021 HDF5 Users Group (HUG) will be held virtually on October 12-14, 2021. More information about the agenda and registration (required) can be found here.
The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC, and the DOE Exascale Computing Project (ECP), organizes the webinar series on Best Practices for HPC Software Developers.
As part of this series, we offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. The October webinar is titled Migrating to Heterogeneous Computing: Lessons Learned in the Sierra and El Capitan Centers of Excellence, and will be presented by David Richards (Lawrence Livermore National Laboratory). The webinar will take place on Wednesday, October 13, 2021 at 1:00 pm ET.
Abstract:
The introduction of heterogeneous computing via GPUs from the Sierra architecture represented a significant shift in direction for computational science at Lawrence Livermore National Laboratory (LLNL), and therefore required significant preparation. The Sierra Center of Excellence (COE) brought employees with specific expertise from IBM and NVIDIA together with LLNL in a concentrated effort to prepare applications, system software, and tools for the Sierra supercomputer. To prepare for El Capitan, a new COE is currently operating in collaboration with HPE and AMD. This webinar will describe the operation of these COEs and document lessons learned, with the hope that others will be able to learn from both our success and intermediate setbacks. We describe what we have found to be best practices for managing the vendor collaborations, migrating algorithms and source code, working with the system software stack and tools, and optimizing application performance.
Strategies for Working Remotely will be a topic of discussion in the next DOE Laboratories of the Future (LOTF) workshop. We hope you will join us!
DOE laboratories are globally recognized to be masters of science at scale, interdisciplinary research, and operating national user facilities. At the same time, the laboratory complex is entering its eighth decade of existence and retains vestiges of its World War II roots. As the stewards of this national treasure, it is our job to ensure the laboratories have the resources and structures to thrive for the next 70 years and beyond.
Purpose of Workshop: The next event in the DOE Laboratories of the Future (LOTF) workshop series will be focused on effective teaming across the DOE laboratories and how we can best integrate new tools and mechanisms for virtual collaboration. Panel speakers will address:
- How do decision-making teams work together effectively?
- How can virtual collaborative tools help stimulate innovative collaborations?
- What are strategies for working remotely at the national labs?
- What new models of collaborative teaming can be adopted?
Panelists:
-
Dr. Nancy Cooke, Arizona State University – Effective Teamwork for DOE Laboratories of the Future
Dr. Gary Olson, University of California, Irvine – Virtual Collaborative Scholarship
Dr. Elaine Raybourn, Sandia National Laboratories – Strategies for Working Remotely
Dr. Francesca Poli, Oppenheimer Science and Energy Leadership Program – Championing New Models of Flexibility to Enhance Scientific Impact
