Discovering and Addressing Social Challenges in the Evolution of Scientific Software Projects
Sep 11 @ 1:00 pm – 2:00 pm

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 next webinar is titled Discovering and Addressing Social Challenges in the Evolution of Scientific Software Projects, and will be presented by Rene Gassmoeller (UC Davis). The webinar will take place on Wednesday, September 11, 2019 at 1:00 pm ET.


In recent years scientific software projects have increasingly incorporated state-of-the-art technical best practices like continuous integration into their development cycle. However, many projects still struggle to create and maintain an active and welcoming user/developer community, and there exists little documentation on what makes a scientific software community successful. In this webinar I will introduce my work — as a Better Scientific Software Fellow — typical social challenges and potential solutions that arise during the evolution of a scientific software project. Aimed at current and prospective software maintainers and community leaders, I will discuss topics such as building and maintaining a welcoming community atmosphere, overcoming skepticism of sharing science and software, mediating between users working on conflicting topics or publications, and providing credit and growth opportunities for community members. Finally, I hope to initiate a conversation among project and community leaders about what makes communities successful so that we can learn from each other and improve scientific software development together.

ECP/NERSC UPC++ Tutorial @ Lawrence Berkeley National Laboratory, Shyh Wang Hall, Bldg 59, Room 59-3101
Nov 1 all-day

Registration is now open for the one day ECP/NERSC UPC++ tutorial.

UPC++ is a C++11 library providing classes and functions that support Partitioned Global Address Space (PGAS) programming. UPC++ provides mechanisms for low-overhead one-sided communication, moving computation to data through remote-procedure calls, and expressing dependencies between asynchronous computations and data movement. It is particularly well-suited for implementing elaborate distributed data structures where communication is irregular or fine-grained. The UPC++ interfaces are designed to be composable and similar to those used in conventional C++. The UPC++ programmer can expect communication to run at close to hardware speeds.

In this tutorial we will introduce basic concepts and advanced optimization techniques of UPC++. We will discuss the UPC++ memory and execution models and walk through implementing basic algorithms in UPC++. We will also look at irregular applications and how to take advantage of UPC++ features to optimize their performance.

This event can be attended on-site at NERSC or remotely via Zoom.  The remote connection information will be provided to the registrants closer to the event.  Registration is required for this event and space is limited so please register as soon as possible. Registration closes for this event when the limit is reached or on October 18, 2019.
